چکیده
O controle de insetos fitófagos como o pulgão da couve Brevicoryne brassicae (Linnaeus, 1758) (Insecta: Hemiptera: Aphididae) geralmente é realizado com inseticidas químicos, que pode causar danos ao ambiente e à saúde humana, bem selecionar resistentes a pesticidas. Dessa forma estabelece-se necessidade pesquisar desenvolver métodos alternativos para couve. Nesse sentido, utilização extratos vegetais ser uma alternativa uso sintéticos, visto os são comprovadamente um meio promissor no pragas. Diante do exposto objetivou-se este trabalho avaliar toxicidade jurema-preta Mimosa tenuiflora marmeleiro Croton sonderianus sobre brassicae. experimento foi desenvolvido Centro Ciências Humanas Sociais Agrárias (CCHSA), Universidade Federal Paraíba (UFPB), Campus III, Município Bananeiras, Estado Paraíba, Nordeste Brasil. Foram utilizados 400 espécimes B. duas espécies vegetais, na etanólico, foram testados em cinco concentrações (0%, 25%, 50%, 75% 100%). ensaio experimental conduzido Delineamento Inteiramente Casualizado esquema fatorial 2x5. Foi avaliada mortalidade 24 h após aplicação dos extratos. possível verificar atividade biológica dois testados, tendo vista ambos causaram inseto alvo, maior destaque extrato M. tenuiflora. Todas as testadas apresentaram Concluindo-se então das Caatinga, aqui testadas, apresentam e, possivelmente, podem método alternativo desse inseto.

Functional response and mutual interference are the most important behavioural characteristics that reveal different aspects of host–parasitoid interactions. In this study, functional response and mutual interference of the parasitoid wasp, Diaeretiella rapae (M’Intosh) attacking the cabbage aphid, Brevicoryne brassicae (Linnaeus) were investigated. Logistic regression was used to distinguish t...
متن کاملSpecies identification of aphids (Insecta: Hemiptera: Aphididae) through DNA barcodes.
A 658-bp fragment of mitochondrial DNA from the 5' region of the mitochondrial cytochrome c oxidase 1 (COI) gene has been adopted as the standard DNA barcode region for animal life. In this study, we test its effectiveness in the discrimination of over 300 species of aphids from more than 130 genera. Most (96%) species were well differentiated, and sequence variation within species was low, ave...
