Interpretive Summary: Insects have developed tolerance against infection by pathogenic fungi through several mechanisms. The effects of infection by pathogenic fungus, Aspergillus flavus on the immune defense system of the Lepidopteran: Spodoptera litura, were investigated. A. flavus infects S. litura by directly reducing the insects immune system, resulting in infection. This report supports the importance of A. flavus as a candidate for biological control of S. litura, and possibly other insect pests.

Technical Abstract: Insects have developed tolerance against mycoses caused by entomopathogenic fungi through several humoral and cellular mechanisms. he effects of infection by pathogenic fungus, Aspergillus flavus on the immune defense system of the Lepidopteran: Spodoptera litura, were investigated. The fungi, A. flavus exposure resulted in modification of antioxidant enzymes levels, and significant decline in phenoloxidase titers, reducing total hemocyte counts at 48 h post exposure. This report supports the importance of A. flavus as a candidate for biological control of S. litura, and potentially other lepidopteran pests.
