Parasitic Effects of Varroa destructor (Acari: Varroidae) on Hypopharyngeal Glands of Africanized Apis mellifera (Hymenoptera: Apidae)
Provedor de dados: 25
Autores: Pinto, Fábio de Assis; Souza, Gabriely Köerich; Sanches, Marcia Aparecida; Serrão, José Eduardo.
The mite Varroa destructor (Anderson &amp; Truemann 2000) (Acari: Varroidae) is one of the most studied parasites of Apis mellifera, as it causes many losses in apicultural business worldwide. Several research studies have demonstrated distinct levels of virulence of the mite and increased colony mortality rates due to its infestation; however only a few studies report the mite's effects on specific tissues, glands or other organs in bees. In this context, this study was conducted with the aim of studying the parasitic effect of the mite V. destructor on hypopharyngeal glands of Africanized A. mellifera. Mean gland cell areas for bees with and without mite infestations were significantly different. Variations in the number of vesicles and the presence of...

The formation of the twin resting cysts in the dinoflagellate Dissodinium pseudolunula, a parasite of copepod eggs
Provedor de dados: 5
Autores: Gomez, Fernando; Artigas, Luis Felipe.
The dinoflagellate Dissodinium pseudolunula is the most common and widespread ecto-parasite of copepod eggs in neritic waters. When the host is absent, the species survives with a distinctive pair of twin resting cysts described as Pyrocystis margalefii. Based on live samples, the formation of the twin resting cysts is illustrated here for the first time. The gymnodinioid infective cells did not form overwintering cysts under unfavourable conditions. These are formed inside the secondary lunate sporangium.

Les parasites d'Arnoglossus laterna (Walbaum, 1792), Bothidae, dans le golfe du Lion (cote francaise de la Mediterranee) et leur influence sur les formules leucocytaires des poissons hotes
Provedor de dados: 5
Autores: Douellou, L; Bastide-guillaume, C; Romestand, B; Trilles, J.
Arnoglossus laterna is only infested by intestinal parasites. Each parasite distribution is independent of the distribution of other parasites and also independent of the sex of host. When a fish is infested by a great number of the two helminths Acanthocephaloides and Bothriocephalus clavibothrium , the proportion of lymphocytes tends to decrease and the proportion of neutrophils tends to increase (inflammatory response). Important infestation by Scolex pleuronectis induces an increase of the thrombocyte count for 100 counted leucocytes. After infestation by the nematode Thynnascaris sp. alone or with another parasite, even by small number, the proportion of lymphocytes decreases and the proportion of neutrophils increases.

Temporal changes in lipid condition and parasitic infection by digenean metacercariae of young-of-year common sole Solea solea (L.) in an Atlantic nursery ground (Bay of Biscay, France)
Provedor de dados: 5
Autores: Durieux, Eric; Galois, Robert; Begout, Marie-laure; Sasal, Pierre; Lagardere, Francoise.
Little attention has been paid to flatfish parasitism as a potential factor of variation in year-class strength. The aim of this study was to evaluate the relationship between parasitic infection and nutritional condition of young-of-year (YOY) common sole. Sole were collected monthly from May (early settlement) to November 2004 in a mussel pole culture area, using a push-net or a trawl, and dissected for parasite identification and counts. Total lipids were extracted from the whole body and lipid classes quantified. Triacylglycerols to sterols (free form) ratio (TAG/ST) was used as an index of nutritional status. Digenean metacercariae infection, characterized by two dominant genera, displayed clear seasonal dynamics and the highest records yet reported...

Resultats d'une intervention sur une parasitose a Proctoeces maculatus (Trematoda, Digenea) affectant la mytiliculture de l'ouest Cotentin
Provedor de dados: 5
Autores: Lebreton, J; Lubert, P.
In 1983, the parasitism of Mytilus edulis L. by Proctoeces maculatus (Loose, 1901) Odhner, 1911 (Trematoda, Digenea, Fellodistomatidae), was recorded for the first time by the authors from mussels farming on stakes (Western Cotentin). After analysing the distribution of the prevalence on the shore and bibliographical data, it was suggested that this parasite must follow a biological cycle that had never been observed on the French coasts and that the most probable host of eggs producer - adult or progenetic metacercaria - would not be a fish but the Prosobranch Gasteropod Nucella lapillus . This was confirmed in 1987. This discovery enabled the authors to support a campaign of eradication of this mussels predatory mollusc. In 1990, the parasitism has...

Spatial variability in digenean metacercariae infection of 0-group common sole Solea solea among nurseries along the French Atlantic coast
Provedor de dados: 5
Autores: Durieux, Eric; Begout, Marie-laure; Sasal, Pierre.
We sampled 0-group sole juveniles (N = 174) in September and October 2003 in 9 major nurseries located along the French Atlantic coast (English Channel and Bay of Biscay). 0-group sole were infected with 3 genera of digenean metacercariae, Timoniella spp. (Acanthostomidae), Prosorhynchus crucibulum and Prosorhynchus sp. A (Bucephalidae), Podocotyle sp. (Opecoelidae), and an unidentified species of Digenea. Parasite infection levels in the English Channel nurseries were lower, and the community composition was different from Bay of Biscay nurseries. We hypothesize that the difference between geographic areas was due to differences in first intermediate host communities and, to a lesser extent, because of lower temperatures in the English Channel compared to...

Effect of trematode parasites on cockle Cerastoderma edule growth and condition index: a transplant experiment
Provedor de dados: 5
Autores: De Montaudouin, X.; Bazairi, H.; Culloty, S.
We quantified the effect of trematode parasites in cockles through a 303 d transplant experiment. Cockles were sampled in 3 different sites on the southwest coast of France characterized by 3 different trematode communities, i.e. Royan (RO): high Meiogymnophallus minutus abundance near cockle heart, South Arguin (SA): high Himasthla interrupta abundance in the mantle margin, and North Arguin (NA): almost free of trematodes. Sampled cockles were individually tagged and placed in different cages at Banc d'Arguin, Arcachon Bay. At the end of the experiment, RO cockles had lost their trematodes, highlighting the fact that trematode lifespan can be short, while SA cockles maintained their trematode load. When cockles were the second intermediate host, there was...

Infestation of the cupped oysters Crassostrea angulata, C. gigas and their first-generation hybrids by the copepod Myicola ostreae: differences in susceptibility and host response
Provedor de dados: 5
Autores: Batista, F. M.; Boudry, Pierre; Dos Santos, A.; Renault, Tristan; Ruano, F.
We Studied the prevalence and intensity of the parasitic copepod Myicola ostreae in 2 closely related oysters Crassostrea angulata and C. gigas and their F1 hybrids. The effects on host and host reaction were also analysed to better understand host-parasite relationships between copepods and bivalve molluscs. Full reciprocal crosses were carried out between C. angulata and C. gigas and the progenies were reared in the wild in Ria Formosa Lagoon (Portugal), allowing natural infestation by M. ostreae. Prevalence and intensity were significantly higher in C. angulata than in C. gigas. The parasite level of F1 hybrids was similar to C. angulata and significantly higher than in C. gigas. The results of our study support a hypothesis of dominantly inherited...

Many deep‐water fish populations, being k‐selected species, have little resilience to overexploitation and may be at serious risk of depletion as a consequence. Sea warming represents an additional threat. In this study, the condition, or health, of several populations of common ling (Molva molva), blue ling (M. dypterygia) and Mediterranean or Spanish ling (M. macrophthalma) inhabiting different areas in the North Atlantic and the Mediterranean was evaluated, in order to shed light on the challenges these deep water species are facing in the context of fishing activity and a warming climate. The data on the condition of Molva populations which we analyze here has been complemented with data on abundance and, for the southernmost species (Mediterranean...

Distribution of parasites in their second intermediate host, the cockle Cerastoderma edule: community heterogeneity and spatial scale
Provedor de dados: 5
Autores: De Montaudouin, X.; Lanceleur, L.
We studied the spatial heterogeneity of infection of the marine bivalve Cerastoderma edule (cockle) by trematode parasites at 5 different scales in Banc d'Arguin, France. At the km-scale, the communities of trematodes differed among stations in terms of species composition and specific abundance. Infection heterogeneity was likely due to the occurrence of the definitive host and the conditions of transmission (water parameters). At the 100 m scale, trematode species richness was similar among stations, but specific trematode abundances differed. The most significant variable in terms of explaining trematode infection heterogeneity was the presence of the first intermediate host. At the 10 m scale, the distance at which parasite abundance diminished varied...

Provedor de dados: 5
Autores: Durieux, Eric.
Coastal areas, such as shallow water bays and estuaries, serve as nurseries for juveniles of many marine fishes and especially flatfishes. Parasites play an important role in these marine ecosystems, but it remains poorly studied. Little attention has been paid to parasitism as a potential factor of variation in flatfish juveniles biological performances in these habitats. Sole juveniles, Solea solea (Pleuronectiformes, Soleidae), that is a species of primary importance for fisheries, are infected by digenean metacercariae. Thus, the aims of this PhD thesis were: i) to determine the spatio-temporal dynamics of the digenean metacercariae infection of 0-group sole juveniles at different scales; ii) to estimate the effects of this infection at different...

Autores: BROCHETTO-BRAGA,M.R.; PALMA,M.S.; RIBEIRO,J.C.; GOBBI,N.
The presence of a polydnavirus in the ovary of the microhymenoptera Apanteles galleriae was detected. This wasp parasites the larvae of the wax moth Galleria mellonella. To study the possible viral effects on the total protein of G.mellonella, hemolymph extracts of the ovary calyxes of parasitized A. galleriae were injected into 6th and 7th instar cells of G.mellonella larvae. Protein profiles on polyacrilamide gel electrophoresis containing sodium dodecyl sulfate (SDS-PAGE) of host cell extracts showed a suppression of several protein bands when infection occurred in the 6th instar. However, in the 7th instar, parasitism caused an amplification in the synthesis of most proteins with some changes in the electrophoretic profile.

Oviposition sequence and offspring of mated and virgin females of Cotesia flavipes (Hymenoptera: Braconidae) parasitizing Diatraea saccharalis larvae (Lepidoptera: Crambidae)
Provedor de dados: 80
Autores: Scaglia,M.; Chaud-Netto,J.; Brochetto-Braga,M. R.; Ceregato,S. A.; Gobbi,N.; Rodrigues,A.
Large scale mass rearing of natural enemies has been a mean of improving biological control in the sugarcane intensive agriculture. Among them, Cotesia flavipes, a gregarious koinobiont endoparasitoid, was imported by Brasil to control caterpillars of the sugarcane borer Diatraea saccharalis. The C. flavipes larval development depends on its association with polydnavirus, which blocks the host defense reaction. To verify if the oviposition sequence (1st, 2nd or 3rd) and the female condition (mated or virgin) interfere in the number of C. flavipes descendents, 4th instar caterpillars of D. saccharalis were parasitized. Analysis of the data showed that: a) there is an inverse correlation between the parasitism efficiency and the host reaction...

Cotesia glomerata is a natural enemy of the vegetable plague Ascia monuste orseis and preferably parasites 2nd, 3rd and 4th instar larvae. Parasitism effects on the haemolymph protein profile of Ascia monuste orseis larvae from the 2nd to 7th days were analyzed both qualitatively and quantitatively by SDS-PAGE and Coomassie-Blue binding methods. Quantitative analysis showed a progressive increase in the protein content of about 6.5 and 12.5 times in parasitized and non-parasitized larvae from the 2nd to 5th days, respectively. On the 6th day, a decrease in protein content was observed in both groups, although this decrease was significantly less than the control group that continued to metamorphosis. Meanwhile, parasitized larvae had one more day (7th day)...

A coral-eating barnacle, revisited (Cirripedia, Pyrgomatidae)
Provedor de dados: 16
Autores: Ross, Arnold; Newman, William A.
The coral-eating barnacle Hoekia monticulariae (Gray, 1831), the only internal parasite among the Thoracica described to this day, is characterized by an irregularly-shaped shell nestled cryptically between the polyps of the hermatypic coral Hydnophora Fischer, 1807, which occurs throughout most of the Indo-West Pacific. Because of its protean form, cirripedologists have failed to appreciate the diversity of taxa related to Hoekia, , a presumed monotypic genus. We describe seven new species divided between Hoekia and three new genera, Eohoekia, Parahoekia, and Ahoekia for which the Tribe Hoekiini is proposed. As in other pyrgomatids, calcareous overgrowth by the coral is inhibited around the edge of the wall and aperture. But in Hoekiini a pseudopolyp,...

Autores: Hoeksema, B.W.; Best, M.B.
Three Indonesian species of Heterocyathus and two of Heteropsammia are briefly diagnosed. Remarks are given on their synonymy, phenotypic variation, and ecology. All five species are found on soft substrata in the proximity of coral reefs and live in association with a sipunculan worm. This interspecific assocation is discussed with regard to whether it is mutualistic or parasitic.

Trap-nest occupation by solitary wasps and bees (Hymenoptera: Aculeata) in a forest urban remanent
Provedor de dados: 82
Autores: Loyola,Rafael D.; Martins,Rogério P.
Temporal variation of solitary wasps and bees, nesting frequency, mortality, and parasitism were recorded from a remanent forest in Belo Horizonte, MG, Brazil. Wasps and bees were collected in trap-nests placed in areas with 25, 100, and 400 m², from February to November 2004. The 137 trap-nests collected contained 11 species of wasps and bees. Wasps occupied most nests (75%). Occupation peaks occurred in March (25%) and September (26%); in June, the lowest occupation (2%) was observed. Except for Trypoxylon (Trypargilum) lactitarse Saussure, no significant correlation was found between number of occupied nests, and temperature and rainfall means. In the nests, 48% of the immature specimens died; 13% of the nests were parasitized. Total death and...

Temporal and spatial variation of Stenoma cathosiota Meyrick (Lepidoptera: Elachistidae) caterpillar abundance in the cerrado of Brasilia, Brazil
Provedor de dados: 82
Autores: Morais,Helena C.; Cabral,Bérites C.; Mangabeira,Jacimary A.; Diniz,Ivone R.
The caterpillars of Stenoma cathosiota Meyrick feed on Roupala montana Aubl. (Proteaceae) in the cerrado of the Distrito Federal, Brazil. They construct shelters by joining leaves of the plant where they feed and pupate. The caterpillars are parasitized by a wasp (Hymenoptera: Brachonidae), which emerges from the pupae. Caterpillar abundance and parasitism frequency were associated in an area of frequently burned cerrado (biennial fire) and in another area that burns sporadically (1987 and 1994). For S. cathosiota, the variation among years in a single area, with sporadic fires, was greater than the variation among areas with different fire regimes. Caterpillar abundance among years was significantly different in the area that burns sporadically (chi² =...

Autores: Bragança,Marcos A.L.; Della Lucia,Terezinha M.C.; Tonhasca Jr.,Athayde.
Phoridae flies parasitize several ant species, including many Atta leaf-cutting ants. In this note, the attacks of three coexisting phorid species (Myrmosicarius grandicornis Borgmeier, Apocephalus attophilus Borgmeier and Neodorhniphora bragancai Brown) against Atta bisphaerica Forel workers in a pasture located in Viçosa County, Minas Gerais State, Brazil, are reported. The first two species of phorids are known to parasitize other leaf-cutting ants. N. bragancai, however, has been found only around A. bisphaerica nests. Each of these phorid species selects ants engaged in different tasks and oviposits in specific sites of the ant body.

Provedor de dados: 82
Autores: Santos,Alex M.; Serrano,José C.; Couto,Ricardo M.; Rocha,Leonardo S.G.; Mello-Patiu,Cátia A.; Garófalo,Carlos A.
Parasites of adult bees are almost exclusively flies and the most important of them are conopids. This note registers for the first time the association of species of Physocephala (Diptera: Conopidae) with Centris (Heterocentris) analis (Fabricius). From 26 females and nine males of the host species found dead inside trap-nests on the campus of the University of São Paulo, Ribeirão Preto, Brazil, 35 parasitoids were obtained belonging to nine species of Physocephala. The data show that C. analis is a host to several conopid flies, and suggest that such parasitoids can play an important role in population control of this bee species.

The genus Diadegma have some species able to parasite Plutella xylostella (L.) (DBM). Laboratory studies were carried out on a Diadegma sp. from Reunion Island to elucidate its ability to parasite DBM larvae, and to determine the influence of the temperature on its fecundity, longevity, oviposition and the consumption of cabbage leaves by parasitized DBM larvae. Parasitism rates were close to 70% for the L2 and L3 instar, and 53% for the L4. At 15°C, there were no progeny. At 20°C and 25°C, the percentage of parasitism was near 70%. At 29°C, the percentage parasitism was similar but the number of males produced was higher. Parasitized DBM larvae consumed 35% less leaf surface than non parasitized larvae. This Diadegma sp. is a possible candidate for...

Un échantillonnage de poissons parasités (Diplodus puntazzo) en provenance d’une firme aquacole située au Sud-est de la Corse (Ouest méditerranéen) montre une infestation due à un Myxidium leei. Le parasite envahit l’épithélium intestinal causant amaigrissement du poisson et une forte mortalité. Les spécimens de plus de 16 cm de longueur totale étaient significativement moins infestés. Toutefois, l’infestation ne montre pas de différence significative entre mâles et femelles quelle que soit la taille des spécimens. Quelques paramètres hématologiques ont été utilisés pour montrer le rôle du parasite dans cette maladie de poissons et statuer sur l’interaction hôte-parasite.

An assessment survey on the austral fish was carried out during the summer 1997 on both the shelf and slope off southern Argentina. The cruise covered 101,508 nm2 between 45° and 54° 30'S and depths between 50 and 400 m. The survey did not include the area controlled by the United Kingdom. Considering the total area as an undivided stratum, a random sampling was used to estimate demersal fish biomass and a delta distribution-based model to evaluate mean densities. Out of the forty five species caught 28 were bony fish and 17 elasmobranch. Four cephalopod mollusc species were also identified. A biomass of 3.2 million tons (CI(95o/o): 1.90 - 6.06 millions) proved that longtail hake was the most abundant resource within the region followed by common hake...

ABSTRACT Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.

Autores: Pratissoli,Dirceu; Zanuncio,José Cola; Vianna,Ulysses Rodrigues; Andrade,Josimar de Souza; Guimarães,Edylene Marota; Espindula,Marcelo Curitiba.
Species of the Trichogramma genus are among the most important ones for biological control. The objective of this research was to evaluate parasitism potential of two species of Trichogramma on eggs of Anagasta kuheniella through life fertility table, at temperatures between 15ºC and 35ºC. These species were collected in the State of Espírito Santo parasitising eggs of the avocado defoliator Nipteria panacea. Trichogramma pretiosum and T. acacioi showed adequate reproductive potential between 15ºC and 35ºC which indicates possibilities of using them in biological control programs in avocado plantations.

The prevalence of Cuterebra simulans bot fly parasitism on marsupial Gracilinanus microtarsus was compared between sexes and seasons of the year. No significant difference was observed between females and males but prevalence was higher in warm-wet season than cool-dry season. This pattern agree with observations of others studies with oestrids flies in southern Neotropical areas, suggesting the occurrence of latitudinal change in the peak of bot flies reproductive activity related to seasons of the year along these systems. This is the first record of C. simulans larvae parasitism on G. microtarsus and its occurrence in southern areas of the Neotropical region.

Hymenoepimecis neotropica (Brues &amp;amp; Richardson) (Hymenoptera, Ichneumonidae, Pimplinae) parasitoid of Araneus omnicolor (Keyserling) (Araneae, Araneidae): first host record and new occurrence to Brazil. The species of the genus Hymenoepimecis occur only in Neotropical region, being recognized for using as their hosts spiders which build orbicular webs. That wasp was described occurring only in the Guyana. This work expands the geographical distribution of the species to Brazil and records the spider Araneus omnicolor (Araneae, Araneidae) as its host. Furthermore, it provides information about the natural history of this interaction.

Provedor de dados: 103
Autores: Fernandes,Noemi M.; Sartini,Bianca; Dias,Roberto J. P.; D'Agosto,Marta.
In this work we investigated the quantitative aspects of the relationship between Rhinella pombali (Baldissera, Caramaschi &amp;amp; Haddad, 2004) tadpoles and their trichodinid ectoparasites. Specimens were collected from a small stream located at an agricultural area between rainforest fragments in southeastern Brazil. A total of 80 tadpoles were investigated. Trichodina heterodentata Duncan, 1977 was the only trichodinid ciliate species recovered. All tadpoles were naturally infested by T. heterodentata with a mean intensity of 695.14 ± 33.33 trichodinid ciliates per tadpole. A positive correlation was observed between the intensity of the infestation and tadpole weight. Intensity of infestation did not significantly influence mean trichodinid diameter...

Bats used as hosts by Amblyomma sculptum (Acari: Ixodidae) in Northeastern Brazil and its implications on tick-borne diseases
Provedor de dados: 103
Autores: Novaes,Roberto Leonan M.; Alves,Fernanda M.; Souza,Renan F.; Laurindo,Rafael S.; Moratelli,Ricardo.
ABSTRACT Amblyomma Koch, 1844 is distributed worldwide, with ca. 130 species currently recognized. These ticks are vectors of pathogens to animals and humans, including the causative agent of the New World Rocky Mountain spotted fever. Species of the Amblyomma parasitize a wide range of organisms, especially medium and large terrestrial mammals. Here we report for the first time the association of Myotis lavali Moratelli, Peracchi, Dias &amp; Oliveira, 2011, Noctilio albiventris Desmarest, 1818 and Noctilio leporinus (Linnaeus, 1758) as hosts for Amblyomma sculptum Berlese, 1888. The ticks were originally identified as Amblyomma cajennense (Fabricius, 1787), in 2011. However, a later taxonomic review indicated that the species of the A. cajennense complex...

Intersexuality in the holotype of Photina gracilis (Mantodea: Mantidae: Photininae) and its taxonomic implications
Provedor de dados: 103
Autores: Agudelo R.,Antonio A.
Parasitism by horsehair worms (Nematomorpha) in Mantodea is well known, but only a few cases of intersexuality were reported in the literature. In the present study, intersexuality of the holotype of Photina gracilis Giglio-Tos, 1915 is documented as a possible consequence of nematomorph parasitism. Photina gracilis and Photina laevis Giglio-Tos, 1915 are established as new subjective junior synonyms of Photina vitrea (Burmeister, 1838). The female holotype of Mantis (Cardioptera) gymnopyga Burmeister, 1838, which was associated and synonymized with P. vitrea, is recognized as a member of the genus Coptopteryx and the combination Coptopteryx gymnopyga (Burmeister, 1838) is revalidated. The substitute name Photina gymnopyga (Burmeister, 1838), instead of...

BACKGROUND: Biotic processes, such as predation and parasitism events, are crucial for answering questions in ecology and evolution. Here, we report predation and ectoparasitism events of invertebrates upon tadpoles in aquatic habitats of southern Brazil. FINDINGS: Four lentic water bodies were sampled twice a month (December 2012 to March 2013). Those water bodies were located in the Diamante do Norte County, State of Paraná, southern Brazil. The tadpoles, Dendropsophus aff. minutus, Hypsiboas raniceps, Scinax fuscovarius, Physalaemus cuvieri and Elachistocleis bicolor were observed being predated by six different invertebrate predators. However, Leptodactylus fuscus and Pseudis sp. were also recorded on the same water bodies and were not observed being...

Main parasitic zoonosis transmitted by fish - a review
Provedor de dados: 195
Autores: Okumura, Maria Paula Martinez; de Pérez, Agar Costa Alexandrino; Espíndola Filho, Antonio.
Parasitic zoonosis transmitted by fish are an ever growing problem which calls the attention of researchers and public health authorities because of the health problems caused to the population after raw / rare fish consumption. In Brazil, dishes based on raw fish, such as "sushi" and "sashimis" are greatly consumed because of the influence of oriental culinary. Data show that there are zoonotic parasites in both Brazilian fresh and sea water fish. However, up to the present, there are no reports of human parasitism in Brazil (except for fagicolosis). It is believed that this statistics are related to the absence of diagnosis rather than the absence of the illness itself. Among diseases transmitted to man by fish consumption are anisakiasis;...

Autores: Cruz,Ivan; Redoan,Ana Carolina; Silva,Rafael Braga da; Figueiredo,Maria de Lourdes Corrêa; Penteado-Dias,Angélica Maria.
Diatraea saccharalis (Fabr.) (Lepidoptera: Pyralidae) spends the largest part of its life cycle inside the stalk of the host plant,which provides protection against the action of conventional control methods. Biological control has been considered a viable alternative to control this pest in sugarcane (Saccharum officinarum L.) and corn (Zea mays L.), two pest preferential hosts. This paper reports the occurrence in Brazil of Tetrastichus howardi (Olliff) (Hymenoptera; Chalcidoidea: Eulophidae) parasitizing pupae of D. saccharalis obtained from corn plants. It also includes preliminary biological data about the insect. A single female of T. howardi is able to produce up to 66 offspring using a single pupa of the host D. Saccharalis and apparently does not...

Cyrtomon luridus (Boh.), a native insect of wild Solanaceae, has adapted to the medicinal plant Duboisia sp., introduced from Australia, causing damages up to 100% mortality. Microctonus sp. is the most important natural enemy of C. luridus and its potential for biological control was investigated in this work. This study was carried out in Arapongas, Paraná State, Brazil, from 1994 to 1996. Parasitism of C. luridus by Microctonus sp. was highest from February through June (maximum of 54% in May 1996), when the C. luridus adult population was decreasing. The female sex ratio of Microctonus sp. under natural conditions was 0.57 to 0.69, which was close to 1 male : 2 female. Production of males occurs parthenogetically (arrhenotoky).

ABSTRACT Diachasmimorpha longicaudata is an Old World parasitoid of tephritid fruit flies that was widely introduced in the Americas to control pest species such as the Mediterranean fruit fly Ceratitis capitata. Augmentative releases in irrigated coffee plantations in semiarid regions of Brazil are under consideration and dispersal capacity of D. longicaudata in this habitat are important to develop release strategies. Approximately 2,000 individuals of D. longicaudata (5 to 7 days old) were released in the center of a fruiting coffee plantation every two weeks from Dec. 2009 to Apr. 2010. Dispersal from the central release point was monitored to the north, south, east, west, northeast, northwest, southeast and southwest at 11 distances, beginning at 4.6...

The parasitoid, Trichogramma spp. was produced using the rice moth eggs Corcyra cephalonica as host. Thus, the study of storage methods was done for the right timing of the parasitoid application during the pest out break. Various storage methods were studied by comparing different set of packed eggs in tissue paper and fire mesh, and unpacked eggs. The eggs were then stored at 5±2°C and 7±2°C for 1-4 weeks. The interaction between temperatures and packing methods resulted in the reduction of egg weight. At 5±2°C reduced fewer egg weight and more larval emergence than that at 7±2°C. Additional emergences were found more in packing eggs with tissue paper than fine mesh and unpacked. The one week storage eggs at both temperatures showed more than 80%...

Autores: Peruquetti,Rui Carlos.
The oviposition behavior and development time of Brachymeria villoso (Oliver, 1790) on Trypoxylon albitarse Fabricius, 1804 (Sphecidae) is reported. The parasitism occurs through a little hole made by the parasitoid female in the host nest wall. This hole is used by the parasitoid offspring after its emergence to left the host nest. The parasitoid egg is laid on the host larva before it built its cocoon, when such structure is made the parasitoid egg hatch into a larva that feeds on the living host larva and the parasitoid growth enclosed in the host cocoon without build its own. The development time of B. villosa was 65 days. From two nest of T. albitarse were reared 12 females and one male of B. villosa.

Autores: Caldas,Astrid.
A different approach was used for the key-factor method in a population study of the tropical butterfly Fountainea ryphea (Cramer, [1776]) (Lepidoptera, Nymphalidae), marking 20 artificial cohorts to identify the mortality levels and associated instars responsible for the variation in numbers within the season of occurrence, when generations overlap broadly. Highest mortality was detected during first instar in 13 cohorts; during second instar in three cohorts; third and fourth instars suffered highest mortality twice. Results showed that first instar mortality due to rainfall and predation, and parasitism on fourth instar could be the main factors promoting differences in number between cohorts throughout the season, although no density-dependent...

Struthanthus flexicaulis is a hemiparasite abundant in ironstone outcrops in southeast Brazil. We evaluated its host preference among species of the plant community, taking into account the abundance and foliage cover of the hosts. The importance of each species in the community and the mortality caused by the parasite were assessed based on a quantitative survey in 10 strips measuring 1m x 50m. The 10,290 individuals belonged to 42 species. Only 15 had a relative abundance in the plant community greater than 1%, of which 12 showed vestiges of parasitism. More than 80% of deaths in the community were associated with parasitism. Non-infected individuals had significantly less mortality rates (7%) than those infected (83%) (²= 1102.4, df = 1, p &lt; 0.001)....

ABSTRACT Parasitic isopods of fishes usually show wide distribution and low host specificity. This study investigated the occurrence of gill parasites in 120 specimens of spotted goatfish Pseudupeneus maculatus, marine fish of great economic importance for fishery community. The fish were captured monthly in the Coast of Pernambuco State, Northeast Brazil, between October 2012 and September 2013. Eleven isopods were found and identified as Rocinela signata. We observed lower infections in the gills of P. maculatus (prevalence 8.3%, mean intensity 1.6±0.3 and mean abundance 0.1±0.3) when compared to other studies of different host fishes from geographically close locations. This parasite has been reported from a wide variety of fish species, not only in...

Autores: de Oliveira Pinheiro,Daniela; Conte,Hélio; Aparecida Gregório,Elisa.
Diatraea saccharalis, the main pest of sugarcane, has been controlled by Cotesia flavipes. Very little is known about the effect of parasitism on the host organs, including the midgut. The Lepidoptera midgut epithelium is composed of columnar, goblet, regenerative, and endocrine cells. Spherites have been described in columnar and regenerative cells of several Lepidoptera species, and presented a lot of functional meaning. We identified spherites in the midgut epithelial cells of non-parasitized D. saccharalis larvae analyzed the effect of parasitism on spherite morphology and distribution along the length of the midgut. Midgut fragments of both non-parasitized and parasitized larvae were processed for transmission electron microscopy. All the midgut...

Occurrence of Pyemotes sp. on Tuta absoluta (Meyrick)
Provedor de dados: 52
Autores: Oliveira,Carlos Romero Ferreira de; Matos,Cláudia Helena Cysneiros; Hatano,Eduardo.
The aim of this work was to study the population reduction of the tomato leafminer moth, Tuta absoluta (Meyrick), by Pyemotes sp. in the laboratory. The mite became greenish when fed on caterpillars, pupae, and adults of T. absoluta. The caterpillars and adults of T. absoluta were quickly paralyzed by the mite venom. A single T. absoluta could host many Pyemotes sp, physogastric females, which were allowed to grow on the moth. Pyemotes sp. can be a new alternative for the biological control of T. absoluta. However, this possibility must be better understood before it could be recommended, because Pyemotes sp. could also cause dermatitis in the humans.

Nesting behavior of the swallow-tailed hummingbird, Eupetomena macroura (Trochilidae, aves)
Provedor de dados: 57
Autores: ONIKI,Y.; WILLIS,E. O.
An August or winter nestling of Eupetomena macroura was fed only every 40-50 min for at least 24 days in the nest, with fewer feedings at midday. As in other hummingbirds, it was brooded only the first week or two, and left alone even on cool nights after 12 days, probably due to the small nest size. The female attacked birds of many non-nectarivore species near the nest, in part probably to avoid predation. Botfly parasitism was extremely high, as in some other forest-edge birds.

Telenomus remus releasing numbers may vary depending on the crop, plant architecture and/or the plant phenological stage. Thus, we examined the number of parasitoids needed for effective pest control of Spodoptera frugiperda on corn, cotton and soybean. In all crops, the parasitism response in relation to increasing numbers of the parasitoids had a quadratic effect. In corn, the maximum parasitism observed was 99.8% and 96.8% at a parasitoid releasing number of 0.231 and 0.264 T. remus females per S. frugiperda egg at phenological stages V4 and V10, respectively. Differently, in cotton and soybean, the highest parasitim were recorded using the highest tested T. remus releasing numbers (0.297 parasitoid per S. frugiperda egg). In cotton, it was 77.8% and...

ABSTRACT: Ticks are arthropods that are highly competent in transmitting pathogens to animals and humans. Among these, the genus Amblyomma is the most representative within the Neotropics. Amblyomma longirostre ticks are naturally distributed in countries of South, Central and North America. Their immature stages preferentially parasitize birds (Passeriformes), while adult stages are usually found on rodents. Therefore, reports of this tick species on wild hosts is epidemiologically relevant, especially because of these ticks' potential for transmitting pathogens to other wild and domestic animals, and also to humans. Thus, the aim of this study was to report infestation by Amblyomma longirostre on Cyanocompsa brissonii in southern Brazil.

The aim of this study is to report the first occurrence of the parasitoid Triplasta coxalis (Ashmead, 1865) (Hymenoptera: Figitidae: Eucoilinae) in pupae of Archisepsis scabra (Loew, 1861) (Diptera: Sepsidae) in cattle dung in Brazil. The experiment was carried out in Monte Alegre, MG. One obtained the pupae through the flotation method. They were individually placed in gelatin capsules until the emergence of the adult dipterous or their parasitoids. Fourty seven pupae of A. scabra were obtained, two of which yielded the parasitoid T. coxalis. The percentage of parasitism was 4.3%.
