Differential effects of Aspergillus flavus and A. parasiticus on survival of Heliothis zea (Boddie) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) reared on inoculated diet
Environmental Entomology 13 (1), 100-104
Abstract: Larvae of the corn earworm, Heliothis zea (Boddie), and the fall armyworm, Spodoptera frugiperda (J. E- Smith), were reared under laboratory conditions on a diet treated with Aspergillus flavus Link or A. parasiticus Speare. Results indicate A. parasiticus is more toxic to the corn earworm than A. flavus when larvae are not transferred daily. The larval stage of the corn earworm sustains more toxic effects than either the pupal or adult stages. When larvae were transferred to fresh diet daily after initial exposure to treated diet, neither the corn earworm nor the fall armyworm showed any significant pathogenic effects (P = 0.01). Overall, toxicity was more evident than pathogenicity.
