FEEDING PREFERENCE OF Spodoptera cosmioides (WALKER) (LEPIDOPTERA:NOCTUIDAE) BY BEAN GENOTYPES

摘要

The black armyworm, Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) is a polyphagous pest of crops and spontaneous plants throughout the Americas (Bavaresco et al., 2004). In Brazil, some of its hosts include bean, soybean, pea, cotton and sunflower. Their occurrence is generally related to the use of non-selective insecticides, resulting in imbalances in the agroecosystem and as a consequence, for example, leads to the reduction of natural biological control agents.
