Avaliação laboratorial do efeito de extratos de Azadirachta indica no controle de Insetos-Praga

Abstract

R E S U M O O feijão caupi (Vigna ungzriculata L.), constitui-se em uma das mais importantes fontes de proteína na alimentação humana, tanto das populações rurais quanto das urbanas, é uma excelente fonte de proteínas com cerca de 23% a 25% em média e apresenta todos os aminoácidos essenciais, carboidratos com 62% em média, vitaminas e minerais, além de grande quantidade de fibras dietéticas e teor de óleo com 2% em média. Um fator limitante que afeta a produção, produtividade, sanidade da planta e do grão afetando o rendimento agronômico da cultura são os insetos-praga, causando danos directos e indirectos, pela regularidade e intensidade de ocorrência, dentre os mais importantes destacam-se: Vaquinha Diabrotica speciosa (Coleoptera: Chrysomelidae), o Pulgão Preto Aphis craccivora (Hemiptera: Aphididae), a Mosca Branca Bemisia tabaci (Hemiptera: Aleyrodidae), a Cigarrinha Verde Empoasca kraemeri (Hemiptera: Cicadellidae) e Mosca Minadora Liriomyza sp. (Diptera: Agromyzidae). Este trabalho teve o objetivo de controlar os insectos-praga com extractos das folhas de Azadirachta indica na cultura do Feijão Caupi (Vigna ungzriculata L.), no campo experimental do Instituto Superior Politécnico do Cuanza Sul (ISPCS) desenvolvendo um estudo laboratorial. Palavras-Chaves Pragas, Insecto, Biopesticidas. Evaluation laboratory of the effect of extracts of Azadirachta indica in the control of insect-curse A B S T R A C T The bean caupi (Vigna ungzriculata L.), it is constituted in one of the most important protein sources in the human feeding, as much of the rural populations as of the urban ones, it is an excellent source of proteins with about 23% to 25% on average and it presents all of the essential amino acids, carbohydrates with 62% on average, vitamins and minerals, besides great amount of dietary fibers and oil tenor with 2% on average. A factor limitante that affects the production, productivity, sanity of the plant and of the grain affecting the agronomic income of the culture is the insect-curse, causing direct and indirect damages, for the regularity and occurrence intensity, among the most important stands out: Cow Diabrotica speciosa (Coleoptera: Chrysomelidae), the Greenfly Black Aphis craccivora (Hemiptera: Aphididae), the Fly White Bemisia tabaci (Hemiptera: Aleyrodidae), the Cicada Green Empoasca kraemeri (Hemiptera: Cicadellidae) and Fly Minadora Liriomyza sp. (Diptera: Agromyzidae). This work had the objective of controlling the insect-curse with extractos of the leaves of Azadirachta indica in Feijão Caupi's culture (Vigna ungzriculata L.), in the experimental field of Cuanza South Polytechnic Superior Institute (ISPCS) developing a study laboratorial. Key word: Prague, Insect, Biopesticidas.
