Avaliação de incidência de inimigos naturais da traça de couve (TDC)(plutela xylostella) no Vale de Infulene

Abstract

The cabbage crop is a great source of nutrition and income for low-income families living in suburban regions. Among several pests that attack its greater production, the cabbage moth (TDC) stands out, whose scientific name is plutella xylostella (linneus) (lipidoptera: plutellidae). The present work was carried out in the Infulene valley with the main objective of evaluating the incidence of the natural enemies of the plutella xylostella (cabbage moth). Studies carried out indicate that peasants in the Infulene valley, due to lack of information and education, do not follow the rules that regulate the proper use of pesticides, which can contribute to the origin of populations of plutella xylostella aluly resistant to these products, thus making their more expensive control and less sustainable production. The use of natural enemies (biological control), which is generally used in an integrated manner, has been assumed to be an adequate control alternative from an environmental, economic and technical point of view, since its application reduces the volume and frequency of the use of chemical products that endanger the environment, their acquisition costs as well as the labor required for their application. From this study, it is concluded that TDC parasitoids belonging to the family Inchneumonidae (Hymenoptera) and superfamily Chaicidoidea (Hymenoptera) as well as the order Diptera occur in the Infulene valley. Of these, the parasitoids belonging to the chalcidoides superfamily behaved as hyperparasitoids.
