DEVELOPMENT AND FITNESS OF Spodoptera cosmioides (WALKER) (LEPIDOPTERA: NOCTUIDAE) ON Phaseolus vulgaris L. GENOTYPES

摘要

The black armyworm Spodoptera cosmioides (Walker, 1858) (Lepidoptera: Noctuidae), is widely distributed in South America, except for southern Argentina, Chile, and regions located to the west of the Andes in Peru (SILVAIN, LALANNE -CASSOU, 1997). In Brazil, this specie has occurred in several crops, including soybean, cotton and bean, causing injuries on leafs and pods that result in substantial losses in the plant yield (SPECHT et al, 2004).
