Gall-inducing insects of deciduous and semideciduous forests in Rio Grande do Sul State, Brazil
Provedor de dados: 76
Autores: Goetz,Ana Paula M.; Luz,Fernando A.; Toma,Tiago S. P.; Mendonça Jr,Milton de S.
ABSTRACT Galls are specific changes induced by insects on plant organs mainly through increases in plant cell number and/or size. Gall diversity is easy to recognize in the field because gallers are mostly species-specific, and thus each gall morphotype can be a proxy for a galling species. Insect galls are virtually unknown in Seasonal Deciduous and Semi-Deciduous forests of southern Brazil. Here, galls and host plants were surveyed between 2015 and 2017 in four forest fragments of Rio Grande do Sul State in these two vegetation types, in secondary-growth and areas under restoration. We recorded 89 gall morphotypes, with gallers belonging to Lepidoptera and Diptera, with the latter represented mainly by Cecidomyiidae. Galls were associated to 46 plant...

Effect of Host Plant on the Fecundity of Spittlebug Deois flavopicta Stal (Homoptera: Cercopidae): Implications on Population Dynamics
Provedor de dados: 82
Autores: SUJJI,E.R.; PIRES,C.S.S.; FONTES,E.M.G.; GARCIA,M.A.
The spittlebug Deois flavopicta Stal (Hom.: Cercopidae) occurs naturally on native grasses in Central Brazil in low population densities. After the introduction of African grasses, mainly of the genus Brachiaria, for cattle raising, D. flavopicta began to produce population outbreaks and became a pest. Two studies were conducted, aiming to estimate the effects of a native and an exotic host plant on the fecundity of this insect. Females of D. flavopicta maintained during the adult stage on Brachiaria ruziziensis produced more eggs and lived longer than those maintained on Axonopus marginatus (a native grass widely distributed in Brazil), independently of the host plant on which the nymphs were reared. Due to the severe damage produced by adult D....

Assemblages of endophagous insects on Asteraceae in São Paulo Cerrados
Provedor de dados: 82
Autores: Almeida,Adriana M.; Fonseca,Carlos R.; Prado,Paulo I.; Almeida-Neto,Mário; Diniz,Soraia; Kubota,Umberto; Braun,Marina R.; Raimundo,Rafael L.G.; Anjos,Luciano A.; Mendonça,Tehra G.; Futada,Silvia M.; Lewinsohn,Thomas M.
A survey of the endophagous insects fauna associated to Asteraceae capitula was carried out from 2000 to 2002 in eight cerrado sensu stricto sites located in the Brazilian state of São Paulo. Sixty-four endophagous species of Diptera and Lepidoptera were recorded from 49 asteracean host plants. Approximately half of the species were obtained from a single locality, with a large proportion emerging from a single sample (unicates). Thirty percent of the species were singletons (i.e. only one individual was recorded). The large proportion of rare species suggests a high species turnover among localities. Lepidopteran species were recorded on more host species than dipterans, confirming their more polyphagous food habit, also observed in other Brazilian biomes...

Autores: WAQUIL,JOSÉ M.; RODRIGUES,JOSÉ A.S.; SANTOS,FREDOLINO G.; FERREIRA,ALEXANDRE S.; VILELLA,FRANCYS M.F.; FOSTER,JOHN E.
Commercial sorghum hybrids and Embrapa's lines were evaluated regarding resistance to sugarcane borer. Two field experiments were conducted in Sete Lagoas, MG, under natural infestation, during the second cropping season in a randomized complete block with 3 replicates. The plants were evaluated regarding to stand, maturity cycle, plant height, and number of broken or lodging stalks and yield. The borer incidence, number of galleries, number of healthy and damaged nodes were also evaluated to calculate the Infestation Index and Intensity Infestation Index. Among the commercial sorghum hybrids, Br 304 and CMSXS 9701 were the least infested wile Z 732 and Esmeralda were the least damaged. Among the lines, the least infested was 9815017 and least damaged...

Interactions between Oncideres humeralis Thomson (Coleoptera: Cerambycidae) and Melastomataceae: host-plant selection and patterns of host use in south-east Brazil
Provedor de dados: 82
Autores: Paulino Neto,Hipólito F.; Romero,Gustavo Q.; Vasconcellos Neto,João.
Oncideres humeralis Thomson (Cerambycidae) was observed girdling the main trunk of plants of the Melastomataceae family in south-eastern Brazil. The main objectives of this work were to identify which host plants O. humeralis selects in the field and which are the characteristics of the preferred plants. O. humeralis specifically used Melastomataceae as host plants, attacking only four of the 11 species present in the study area. From the four attacked species, Miconia sellowiana Naudin and M. jucunda Triana were the preferred owes; they are the most abundant and the largest species, respectively. When the plants were taller, O. humeralis girdled the trunk at higher positions, indicating that females select plants with optimum trunk diameter and adjust the...

Provedor de dados: 82
Autores: Silva,Laura A.; Maimoni-Rodella,Rita C.S.; Rossi,Marcelo N.
This is the first record of Acanthoscelides schrankiae Horn. feeding in seeds of Mimosa bimucronata (DC.) Kuntze. We investigated the pattern of oviposition and seed exploitation by A. schrankiae, and the distribution of mature fruits and seed predation in the inflorescences. We also compared the percentage of predated seeds, the total dry weight of fruits and non-predated seeds, the percentage of aborted seeds, and the percentage of non-emergent insects, among different quadrants of the M. bimucronata canopy. To determine the occurring species, the emergence of bruchids and parasitoids was observed in the laboratory, resulting altogether, only in individuals of A. schrankiae and Horismenus sp. (Hymenoptera: Eulophidae) species, respectively. Mean number...

Effect of nitrogen on Passiflora suberosa L. (Passifloraceae) and consequences for larval performance and oviposition in Heliconius erato phyllis (Fabricius) (Lepidoptera: Nymphalidae)
Provedor de dados: 82
Autores: Kerpel,Solange M.; Soprano,Eliséo; Moreira,Gilson R.P.
The present study examines the influence of nitrogen on growth rates, morphological and nutritional characteristics of Passiflora suberosa L., and the corresponding consequences for Heliconius erato phyllis (Fabricius) growth and oviposition. The treatments consisted of different nitrogen doses (0, 150 and 300 mg L-1) applied to the soil. Newly emerged larvae were individually reared in the laboratory (25 ± 1ºC) on branches of P. suberosa obtained from plants grown under the three nitrogen levels, and field collected females were submitted to oviposition choice tests. P. suberosa growth rates, leaf area and internode length increased significantly when grown with nitrogen enriched soil. P. suberosa presented significantly greater leaf toughness when grown...

Herbivore handling of a Plant’s trichome: the case of Heliconius charithonia (L.) (Lepidoptera: Nymphalidae) and Passiflora lobata (Killip) Hutch. (Passifloraceae)
Provedor de dados: 82
Autores: Cardoso,Márcio Z.
Trichomes reduce herbivore attack on plants by physically and/or chemically inhibiting movement or other activities. Despite evidence that herbivores are negatively affected by trichomes there also reports of insect counter-adaptations that circumvent the plant’s defense. This paper reports on a study that investigated the likely mechanisms employed by larvae of the nymphalid butterfly, Heliconius charithonia (L.), that allow it to feed on a host that is presumably protected by hooked trichomes (Passiflora lobata (Killip) Hutch). Evidence were gathered using data from direct observations of larval movement and behavior, faeces analysis, scanning electron microscopy of plant surface and experimental analysis of larval movement on plants with and without...

Microscopic variability in mechanical defence and herbivory response in microphyllous leaves of tropical herb species from Serra do Cipó, Brazil
Provedor de dados: 88
Autores: Ribeiro,Sérvio Pontes; Corrêa,Tatiana Lopez; Sousa,Hildeberto Caldas de.
Tropical high altitude grasslands present several species with both microphyllous and highly sclerophyllous leaves, and co-occur in specific soil patches, thus exposed to identical environments. In this article we describe herbivory among co-occurring microphyllous species in a tropical high altitude grassland ecosystem of Serra do Cipó, Minas Gerais state, and we tested the effect of variable anatomic traits on leaf herbivory patterns. Leaf anatomical traits were investigated for Baccharis imbricata Heering , Lavoisiera imbricata DC. and L. subulata Triana (focal species). Herbivory was measured from branches and leaves of individual plants and compared among co-occurring species within one multispecific shrub patch and among L. subulata individuals from...

(Test of hypotheses about herbivory and chemical defences of Qualea parviflora (Vochysiaceae) in Brazilian Cerrado). Qualea parviflora Mart. (Vochysiaceae), a widely distributed tree found in different habitats in Brazilian Cerrado (savanna), provides resources for a great variety of insects. In this study, we tested two hypotheses about plant investment in anti-herbivore defences along a fertility gradient in Cerrado: the carbon/nitrogen balance (CNBH) and resource availability (RAH). We also investigated how the pattern of herbivory varies through the year and among three types of vegetation in Brazilian Cerrado - campo sujo, cerrado sensu strictu and cerradão. Sampling was conducted in three types of vegetation and in rainy (January and November) and...

Insect feeding preferences on Piperaceae species observed in São Paulo city, Brazil
Provedor de dados: 92
Autores: Vanin,Sérgio A.; Ramos,Clécio S.; Guimarães,Elsie F.; Kato,Massuo J.
Piperaceae species have been placed among the basal angiosperm and are adapted to a variety of habitats including moist forests, secondary vegetation and dry high lands. The major anatomical/morphology features are of small trees, vines, and shrubs for Piper species, while the epiphytic and succulent characteristics are predominant forms among Peperomia species. Their secondary chemistry can be mostly represented by amides, phenylpropanoids/lignoids, and chromenes in addition to a phletoria of biosynthetically mixed-origin secondary compounds. Although several amides and lignans are known as insecticides, several phytophagous insects, among which some considered pests of economic importance, have been observed feeding vigorously on Piperaceae species....

Gall midge attack intensity and host-plant response in a Neotropical coastal ecosystem
Provedor de dados: 92
Autores: Constantino,Pedro de Araujo Lima; Monteiro,Ricardo Ferreira; Wilson,Machelle D.
The gall inducer Clusiamyia nitida Maia, 1996 (Diptera, Cecidomyiidae) often infests the shrub Clusia lanceolata (Camb.) (Clusiaceae) in the Neotropical vegetation of restinga of Rio de Janeiro State, Brazil. Leaves of Clusia lanceolata host up to 20 spheroid galls and show variation in their shape. We aimed to evaluate the effect of gall's intensity on leaves of Clusia lanceolata, and the extension of gall's impact on adjacent non-galled leaves. We analyzed the effect of the number of galls on leaf area, biomass, specific area and leaf appearance from 509 leaves of 14 individual plants. The results showed that differences of individual plants, pairs of leaves, and gall presence were responsible for more then 90% of variation on infested leaves. Variation...

Feeding site of the spittlebug Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) on sugarcane
Provedor de dados: 63
Autores: Garcia,José Francisco; Grisoto,Eliane; Botelho,Paulo Sérgio Machado; Parra,José Roberto Postali; Appezzato-da-Glória,Beatriz.
The sugarcane spittlebug Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) is a pest of mechanically-harvested sugarcane in Brazil, when trash burning is not performed. To better understand the differences in feeding behavior of adults and nymphs of this pest and the subsequent disorders that arise, stylet penetration through fixation, staining and sectioning was investigated. Nymphs cause a "physiological disorder" damaging the tracheary system of the roots, slowing or preventing water and nutrient flow, with phloem and xylem dehydration. Nymphs insert their stylets through the epidermis, crossing the cortex, endodermis and pericycle before reaching the vascular cylinder, where they feed in the sieve-tube elements of the primary phloem. In contrast,...

Provedor de dados: 39
Autores: Detoni,Michelle de Lima; Vasconcelos,Eveline Gomes; Rust,Naiara Miranda; Isaias,Rosy Mary dos Santos; Soares,Geraldo Luiz Gonçalves.
Two species, Tanaostigmodes ringueleti and T. mecanga, induce distinct galls on Calliandra brevipes Benth (Fabaceae: Mimosoidae), a globose and a fusiform gall morphotype. Seasonal changes of phenolic content in the tissues of the two distinct galls were compared to those of non-galled leaves and stems of the host plants over one year. The variation in the phenolic content profiles was similar in both non-galled and galled tissues, and was primarily associated with changes in the levels of rainfall, indicating a direct response to hydric stress. In periods of drastic changes in water precipitation, the alterations were significantly higher in non-galled than in galled tissues suggesting that the gall inducers might limit the variation in the phenolic...

Floral resins of Philodendron adamantinum (Araceae): secretion, release and synchrony with pollinators
Provedor de dados: 39
Autores: Gonçalves-Souza,Patrícia; Schlindwein,Clemens; Paiva,Elder Antonio Sousa.
ABSTRACT Philodendron is the only genus of Araceae in which resin release occurs in the inflorescence. The resinous secretion adheres to the smooth body surface of the pollinating scarab beetles and allows attachment of pollen grains, making its transport possible. In order to understand the process of resin synthesis and release to the external environment, we used structural, ultrastructural and histochemical analyses at different stages of development of the inflorescences of Philodendron adamantinum. Two types of secretory canals were observed in the spathe: small caliber canals near the abaxial face, and larger caliber canals in the adaxial region. Only the latter canals release secretion into the external environment. The secretory epithelium in...

Provedor de dados: 3
Autores: Teixeira, Ana Paula; Silva, Paulo Fernandes Roges Souza; Souza, João Paulo Francisco de; Alves, Natália Lopes; Guimarães, Ariane; Carneiro, Fernanda Melo.
We performed a scientometry to validate trends in the scientific production on phytotelmata and the importance of these microenvironments in the maintenance of biodiversity. We searched for articles in the Web of Science and looked at publications from 1987 to 2016. We collected years of publication, surveyed organisms, countries where the surveys took place, plants that accumulate phytotelmata, scientific journals that publish more about the topic and their respective IFs (Impact Factor) and the keywords of each article. We built a heatmap using the most frequent keywords in the studies, to investigate the topics studied over the years. We have found 293 publications, increasing over the years. Insects, anurans and crustaceans were the most studied...

Insect galls of Itamonte (Minas Gerais, Brazil): characterization and occurrence
Provedor de dados: 49
Autores: Maia,Valéria Cid.
Three sites of Itamonte (Minas Gerais) were investigated for insect galls from September, 2011 to July, 2012, seasonally. One-hundred and one morphotypes of insect galls were recorded on 63 species of host plant (45 genera and 23 families). Melastomataceae was the most galled plant family, followed by Asteraceae and Myrtaceae. Galls were recorded on leaves, stems, buds, and aerial roots. Leaves were the most galled plant organ. The gall morphotypes were characterized according to their shape, color, pubescence, and number of internal chambers. Globose and fusiform galls were the most frequent. The majority was glabrous and one-chambered. The gallers comprised three insect orders: Diptera (Cecidomyiidae and Tephritidae), Hemiptera, and Lepidoptera....

Induced response against herbivory by chemical information transfer between plants
Provedor de dados: 61
Autores: Campos,Wellington G.; Faria,Ana P.; Oliveira,Maria Goreti A.; Santos,Hérica L.
Plants respond to herbivores and pathogens attack with increased emission of volatile organic compounds. These molecules act as indirect defences when attracting natural enemies of herbivores and thus benefit the plant. It remains controversial whether undamaged plants capture chemicals released by damaged neighbouring plants and respond to them by increasing their defensive barriers against an imminent attack. In spite of public appeal and of this being the 25th year of the Talking Trees Hypothesis, only recently have the most sceptical scientists been convinced. The induced response to herbivory by interplant information transfer has been found in two plant-herbivore systems. However, the universality of the phenomenon and its ecological and evolutionary...
