Soybeans (Glycine max (L.) Merrill) are host of several insect pests along its cycle, since germination to the maturity stage. Exception made for the germination to seedling stage, soybean yield and the quality of seeds and grains are far more affected during the reproductive stage when pods are present, as compared to the vegetative or flowering stages. Pests attacking soybeans during the vegetative stage are chiefly defoliators (lepidopterous and coleopterous), while pod feeders (stinkbugs and pod feeders or pod borers) are more important from pod set to maturity. During the flowering period, before pod set, only defoliator insect pests are considered harmful to soybeans. Nevertheless, this is not true for indeterminate cultivars, because there is an overlapping period of ca. 15-20 days of blooming with pod set and fill and even the beginning of seed fill.
