Atividade ovicida de extratos aquosos de meliáceas sobre a mosca branca Bemisia tabaci (Gennadius) biótipo B em tomateiro

Abstract: RESUMO: A mosca branca Bemisia tabaci (Gennadius) biótipo B atualmente é uma das principais pragas do tomateiro. O uso de extratos botânicos no controle desse inseto é uma alternativa promissora, mas que ainda precisa ser melhor pesquisada. O presente trabalho teve como objetivo determinar a bioatividade de extratos aquosos de folhas de Melia azedarach L. e de ramos de Trichilia pallida Swartz, sobre a mosca branca Bemisia tabaci (Gennadius) biótipo B, criada em tomateiro. Foram realizados dois experimentos, a… Show more

“…A parcela foi constituída por três folíolos de cada genótipo. O confinamento dos insetos deu-se em gaiolas de voil (15 cm x 5 cm), fechadas com velcro (Souza & Vendramim 2000). Adultos da mosca-branca (50 casais) foram aspirados da criação estoque e introduzidos na gaiola, onde permaneceram durante 24h para oviposição.…”
