Aqueous extracts of neem, Azadirachta indica A. Juss., leaf and seed cake were tested for toxicity in Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) utilizing different methods application (foliar systemic). Probit analysis was used to determine the LC50 regression mortality at concentrations (0.5%, 1.0%, 1.5%, 2.0% control treatment). Two caterpillar morphometric variables (larval length cephalic capsule width) scale damage attacked plants measured and, analyzed using...
Resumo: O objetivo deste trabalho foi avaliar o desempenho de Trichogramma galloi (Hymenoptera: Trichogrammatidae) sobre ovos Diatraea flavipennella e D. saccharalis (Lepidoptera: Crambidae), assim como as características biológicas do parasitoide em ambos os hospedeiros, elaborar a tabela vida fertilidade. Para isso, foram realizados testes com sem chance escolha bioensaios para hospedeiros. A fertilidade elaborada por meio parasitismo diário das fêmeas T. Os resultados da percentagem...
RESUMO:Estudou-se o efeito de extratos aquosos inhame (0; 5; 10; e 20% p/p) mastruz 2; 4; 6; 8 10% na biologia da lagarta-do-cartucho. Secções folhas milho foram mergulhadas por 30 segundos em soluções cada concentração; após a secagem, colocou-se secção uma lagarta recém-eclodida. Foram avaliadas viabilidade duração das fases larval pupal, peso comprimento lagartas pupas. Em relação ao extrato inhame, concentração causou maior influência fase larval, sendo reduzida para 12%, com 7 dias,...
Ants are known to function as reliable biological indicators for habitat impact assessment. They play a wide range of ecological roles depending on their feeding and nesting habits. By clustering ants in guilds, it is possible both assess how agriculture forest fragmentation can disturb ant communities predict the impacts due losses specific guild. This study aimed at determining non-shaded coffee pasture predatory omnivorous guilds leaf-litter Atlantic Forest fragments Minas Gerais, Brazil....

Developmental characteristics and parasitism potential egg parasitoids Telenomus alecto Crawford (Hymenoptera, Scelionidae) Trichogramma galloi Zucchi Trichogrammatidae) were compared with aim selecting a suitable species for biological control D. flavipennella. Both T. developed well readily adapted to eggs as host. Although, presented higher...
<p>O pulgão preto, <em>Aphis craccivora </em>Koch (Hemiptera: Aphididae), é considerado uma importante praga do feijão-caupi, <em>Vigna unguiculata</em> (L.) Walp (Fabaceae), pois se alimenta da seiva e transmite viroses. Com o surgimento de novas cultivares feijão-caupi torna-se necessário estudo resistência dessas plantas frente ao ataque das pragas. O trabalho objetivou avaliar os aspectos biológicos <em>A. </em>sobre três (Gurguéia, Vita 7 TVu...
Neosilba spp. is firstly reported in physic nut fruits (Jatropha curcas), Rio Largo, State of Alagoas, Brazil. A total 438 specimens were found on 1,000 between May and July 2010. Five species recorded the Alagoas: zadolicha McAlpine & Steyskal 1982, glaberrima (Wiedemann, 1830), certa (Walker, 1850), pendula (Bezzi) bella Strikis Prado 2008. This first record J. curcas as host plant
Studies on frugivorous flies in Alagoas State, Brazil, have been limited to species of fruit (Tephritidae). This paper reports six Neosilba (Lonchaeidae) five municipalities State: bella, N. certa, glaberrima, inesperata, pendula and zadolicha.
A pinha, Annona squamosa L., é uma frutífera tropical da família anonácea, cujo mercado tem-se ampliado a cada ano, sendo cultivada expressivamente na região Nordeste, onde pequenos produtores têm como principal fonte de renda. Entretanto, problemas causados pelas duas pragas-chave, Cerconota anonella (Sepp.,1830) (Lepidoptera: Oecophoridae) e Bephratelloides pomorum (Fab.,1808) (Hymenoptera: Eurytomidae), limitado produção e, consequentemente, comercialização dos frutos. No intuito...
The effects of ethanolic and hexanic extracts soursop sugar apple (EES, EHS, EESA EHSA, respectively) on Aphis gossypii (Hemiptera: Aphididae) its natural enemy Eriopis connexa (Coleoptera: Coccinellidae) by contact exposure, residual effect ingestion tests were evaluated. estimated LC50 LC99 values for A. 0.39% 5.47% (EESA); 0.23% 1.19% (EES); 0.47% 4.39% (EHSA); 0.42% 6.38% (EHS), respectively. Considering EES at was innocuous, EHS slightly harmful; adult ladybugs, only (5.47%) classified...

Chrysopids (Neuroptera: Chrysopidae) are generalist predators that have application in the biological control of a range open-field and greenhouse pests. We investigated biology Leucochrysa (Nodita) azevedoi fed with nymphs adults Brevicoryne brassicae L. Toxoptera citricida (Kirkaldy 1907) (Hemiptera: Aphididae), eggs, pupae Aleurocanthus woglumi (Ashby) Aleurodicus magnificus (Costa Lima 1928) Aleyrodidae), established predatory capacity chrysopid by determining its functional responses...
ABSTRACT: With the aim of developing tools for simultaneously managing Rhynchophorus palmarum and coconut stem bleeding disease, we evaluated effects insecticide thiamethoxam fungicide cyproconazole on R. larvae under laboratory conditions. Early-instar intermediate-instar were fed an artificial diet containing 0.1% concentration insecticide, or a mixture both. Larval mortality was assessed daily during 48 hours after application treatments. Mean values subjected to analysis variance...
