Resumo: | ABSTRACT:  A deep insight into the population dynamics of a pest can be achieved by being acquainted with its nutritional ecology, which further assists in understanding the damage potential and decisions to control mainly in diversified production systems such as those in Brazil. The present r research aimed to evaluate the effect of dietary regimens, comprising combinations of acessible organs of soybean plants, at different stages of development, consumption, and utilization of food by the 4th, 5th, and 6thlarvae instar of Helicoverpa armigera (Hübner) (Lep.: Noctuidae). For this purpose, the vegetative and reproductive organs of soybean were brought together in three feeding regimes, followed by making it available to caterpillars. After evaluations, it was found that under laboratory conditions, the development of H. armigera 4th to 6th instar caterpillars was better when they werepurely fed on leaves than on combinations of vegetative and reproductive parts, such as fresh leaves + old leaves + pods at the beginning of grain development, and old leaves + pods at the beginning of grain development +pods with well-developed grain.
