Parasitoides no controle biológico de Tefritídeos na amazônia brasileira. Repositório Alice
ADAIME, R..
Na Amazônia brasileira, as pesquisas sobre parasitoides de Tephritidae avançaram nos anos recentes. Estão assinaladas nove espécies de Braconidae (duas não formalmente descritas), sendo Doryctobracon areolatus (Szépligeti) e Opius bellus Gahan as mais abundantes e amplamente distribuídas. Entre os Figitidae, ocorrem quatro espécies, com predomínio de Aganaspis pelleranoi (Brèthes). Algumas espécies vegetais apresentam potencial como "multiplicadoras de parasitoides", como Spondias mombin (Anacardiaceae) e Bellucia egensis (Melastomataceae), com índices de parasitismo de até 50% dos pupários. Bellucia grossularioides (Melastomataceae) apresenta parasitismo de até 20%, porém torna-se relevante em função de sua elevada abundância e ampla distribuição....

Supplementary taxonomic description of Demidospermus pinirampi (Monogenoidea, Dactylogyridae), with a new host record and an expansion of its distribution range Acta Amazonica
AGUIAR,Julio Cesar Cenci de; BUENO,Glauco Baptista Franco; SANTOS,Sonia Maria Cursino dos; ADRIANO,Edson Aparecido.
ABSTRACT During a survey conducted in the Lajeado Reservoir of the Tocantins River, in the state of Tocantins, Brazil, dactylogyrids were recovered from the gills of Pimelodina flavipinnis. Initial morphological analysis showed these dactylogyrids shared aspects of character with species of Demidospermus, with affinity to Demidospermus pinirampi, despite exhibiting differences with the original description by Kritsky et al. (1987) regarding the vagina, the base of the male copulatory organ and the shape and length of the bars. The analysis of the holotypes of D. pinirampi and its most morphologically close species, Demidospermus luckyi, revealed that these dactylogyrids were indeed D. pinirampi. This study therefore reports a new host and locality of...

Diagnostic quantitatif de Perkinsus atlanticus (Apicomplexa, Perkinsea) chez les palourdes Ruditapes decussatus et Ruditapes philippinarum ArchiMer
Almeida, Manuela.
Le protozoaire parasite Perkinsus atlanticus (Azevedo, 1989) est une des causes des chutes de production de palourdes Ruditapes decussatus et R. philippinarum cultivées au Portugal, en Espagne et en Italie. Des modèles d'infection de Perkinsus ont été réalisés, par reproduction expérimentale de la maladie, pour étudier le rôle de la densité des palourdes, de la température et de la salinité sur le déroulement de la Perkinsiose. L'objectif de ce travail a été de développer une technique de diagnostic quantitative pour optimiser l'évaluation de l'intensité d'infection et détecter de faibles infections des palourdes par P. atlanticus. Le principe de cette technique consiste à cultiver tous les tissus de la palourde en milieu thioglycolate, suivi d'une lyse à...

Effects of temperature and salinity on the survival of Bonamia ostreae parasite infecting falt oyster Ostrea edulis in sea water ArchiMer
Arzul, Isabelle; Bond, Celine; Gagnaire, Beatrice; Chollet, Bruno; Morga, Benjamin; Ferrand, Sylvie; Robert, Maeva; Renault, Tristan.
Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting flat oysters Ostrea edulis. The parasite has been described in different ecosystems from estuaries to open sea and no clear correlations could be demonstrated between the development of the disease and environmental parameters such as temperature or salinity. The parasite life cycle, including its survival outside the host is not completely known. Nevertheless, the infection can be directly transmitted by cohabitation between infected and non infected oysters suggesting that the parasite does not need intermediate host to complete its cycle. In the present study, the impact of temperature and salinity on the survival of purified parasites...

Flow cytometry to measure impact of temperature and salinity on the survival of Bonamia ostreae, parasite infecting flat oyster Ostrea edulis, in seawater ArchiMer
Arzul, Isabelle; Bond, Celine; Gagnaire, Beatrice; Morga, Benjamin; Chollet, Bruno; Ferrand, Sylvie; Robert, Maeva; Renault, Tristan.
Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting the flat oyster, Ostrea edulis. After its first description in June 1979ı in Brittany, the parasite rapidly spread to all French oyster farming areas and in other European countries through transfers of live molluscs. The parasite has been described in different ecosystems from estuaries to open sea and no clear correlations could he demonstrated between the disease development and environmental parameters like temperature or salinity. The infection can he directly transmitted by cohabitation between infected and non infected oysters. Nevertheless, the parasite life cycle, including its survival outside the host, is not completely...

Molecular characterization of parasites of the genus Perkinsus present in clams from French producing areas ArchiMer
Arzul, Isabelle; Michel, Justine; Chollet, Bruno; Robert, Maeva; Miossec, Laurence; Garcia, Celine; Francois, Cyrille.
Production of clams is the third most important bivalve production in France and was estimated at 3400 metric tons in 2001 among which 60% came from aquaculture and 40% from fisheries. Surveillance of clam diseases mainly relies on histology and thioglycolate culture, two techniques allowing detection of parasites of the genus Perkinsus but not specific enough to determine the parasite species. Based on a previous study aiming at estimating distribution and prevalence of perkinsosis in France, we selected 34 infected clams from 4 different producing areas in order to characterize the parasite species. Molecular characterization was done by PCR-RFLP targeting the ITS region as described by Abollo et al. (2006). 16 PCR products were cloned and 10 to 20...

Host-parasite interaction and impact of mite infection on mosquito population Rev. Bras. entomol.
Atwa,Atwa A.; Bilgrami,Anwar L.; Al-Saggaf,Ahmad I.M..
ABSTRACT During the present study, the host-parasite relationship between mosquitoes and parasitic mites was investigated. The 8954 individuals of male and female mosquitoes belonging to 26 genera: seven each of Aedes and Culex, six of Anopheles and one each of Toxorhynchites, Coquillettidia and Uranotaenia were collected from 200 sites. The male and female mosquitoes were collected from the State of Uttar Pradesh, located at 26.8500° N, 80.9100° E in North India by deploying Carbon dioxide-baited and gravid traps. The intensity of mite's infection, type and number of mites attached to mosquitoes, mite's preference for body parts and host sexes were the parameters used to determine host-parasite relationship. Eight species of mites: Arrenurus acuminatus,...

Pipetman et bottes en caoutchouc à la recherche d'hôte(s) de Marteilia refringens ArchiMer
Audemard, Corinne; Le Roux, Frédérique; Sauriau, Pierre-guy; Sautour, Benoît; Combes, C.; Coustau, C.; Blachier, Philippe; Berthe, Franck.
Over the last thirty years, the French production of flat oyster Ostrea edulis dropped from15,000 tons/year to 1,500 tons. Marteilia refringens, a parasite of the flat oyster's digestive gland, is partly responsible for this drop. The fight against this pathogen agent requires a better knowledge of its parasitic cycle. The main hypothesis is the existence of a heteroxenous cycle, that is to say a cycle involving more than one host. However, for thirty years this or these hosts have not been found, and the cycle of Marteilia refringens remains unknown.

Bonamia ostreae (Pichot et Coll., 1979) parasite de l'huître plate : comparaison de deux méthodes de diagnostic ArchiMer
Bachere, Evelyne; Durand, Jean-louis; Tige, Gilbert.
The parasite, Bonamia ostreae, was diagnosed in several South Brittany flat oyster's samples, from gills tissues's prints, stained in May-Grunwald-Giemsa and from corresponding digestive glands sections. The comparaison of results shows quantitative differences relating to the infested oyster's rate, and qualitative differences relating to the early stages of infestation. Gill's print technic seems more intersting for the only Bonamia ostreae diagnosis.

Mise en évidence d'Haplosporidium sp. (Haplosporida - Haplosporidiidae) parasite de l'huître plate Ostrea edulis L. ArchiMer
Bachere, Evelyne; Grizel, Henri.
A new Haplosporidie has been observed in the flat oyster Ostrea edulis from the Mediterranean Sea. Different development stages have been described in light and electron microscopy. The characteristics of the spores and especially the presence of at least four sporal filaments enable us to distinguish this Haplosporidie from those already described in the Atlantic flat oysters. Different haplosporidies have been described in the oyster. Some are known as being pathogenic, Minchinia costalis (Andrews et al., 1962 and 1978; Couch 1967) and Minchinia nelsoni (Haskin et al., 1966; Farley 1968 and 1975), others, identified only recently, are considered as occasional parasites (Van Banning, 1977). During the research conducted on Bonamia ostreae (Pichot et al.,...

Patterns of the parasite communities in a fish assemblage of a river in the Brazilian Amazon region. Repositório Alice
BAIA, R. R. J.; FLORENTINO, A. C.; SILVA, L. M. A.; TAVARES-DIAS, M..
This paper characterizes the pattern of ectoparasite and endoparasite communities in an assemblage of 35 sympatric fish from different trophic levels in a tributary from the Amazon River system, northern Brazil. In detritivorous, carnivorous, omnivorous and piscivorous hosts, the species richness consisted of 82 ectoparasites and endoparasites, but protozoan ectoparasites such as Ichthyophthirius multifiliis, Piscinoodinium pillulare and Tripartiella sp. were dominant species predominated, such that they were present in 80% of the hosts. The taxon richness was in the following order: Monogenea > Nematoda > Digenea > Crustacea > Protozoa > Acanthocephala = Cestoda > Hirudinea. Among the hosts, the highest number of parasitic associations...

Validation in commercial conditions of the response to selection of the European flat oyster Ostrea edulis for resistance to Bonamia ostreae ArchiMer
Bedier, Edouard; Langlade, Aime; Angeri, Stéphane; Brizard, Raphael; Nerlovic, V.; Glize, Philippe; Haffray, Philippe.
Since the outbreaks of the parasitosis with Marteilia refringens and Bonamia ostreae in the last 60's, the French production of the European flat oyster dropped from 20000 mT to less than 1500 mT currently, leaving the French shellfish farming in situation of virtually monoculture of the Pacific cupped oyster Crassostrea gigas. To sustain this traditional culture, Ifremer has developed, at the experimental level, a genetic selection for a better tolerance to Bonamia ostreae which led to an improvement of survivals. The transfer of these results to the business scale requires the control of the reproduction in hatchery and the adaptation of the cycle of production to the constraints of seedlings in deep water as practised in Brittany (France). That's why a...

Reproduction of Pratylenchus zeae on Weeds Planta Daninha
BELLÉ,C.; KASPARY,T.E.; KUHN,P.R.; SCHMITT,J.; LIMA-MEDINA,I..
ABSTRACT Weeds can be hosts of root-lesion nematode (Pratylenchus spp.), maintaining or increasing their population in the soil. The objective of this study was to evaluate the reaction of 25 weeds species to the nematode Pratylenchus zeae. The weed plants were individually inoculated with 1,000 individuals of P. zeae and maintained in a greenhouse for 90 days. After this period, eggs and nematodes were extracted, quantified, and the reproduction factor (RF = final population/initial population) was calculated. All tested weeds were susceptible (RF>1) to P. zeae, and the species Brachiaria decumbens, Rhynchelytrum repens, Digitaria insularis, D. horizontalis, B. brizantha were the most susceptible to this parasite.
