Formosan subterranean termites (FST) were exposed to strains of Beauveria pseudobassiana (Bpb) and Isaria fumosorosea (Ifr) to determine virulence of the fungi. Once lethality was determined, sublethal doses of Bpb were combined with enzymes capable of degrading the insect cuticle to measure the potential to enhance fungal infection. Bpb applied to FST in combination with proteinases and a chitinase caused increased mortality over the fungus alone. Mortality was enhanced when Ifr was applied to FST in combination with a chitinase isolated from Serratia marcesans. A lipase isolated from Pseudomonas cepacia, when combined with Ifr, also resulted in greater mortality than all control treatments. FST were also exposed to the eicosanoid biosynthesis inhibitors (EBIs) dexamethasone (DEX), ibuprofen (IBU), and ibuprofen sodium salt (IBUNA), in combination with Ifr. Combining Ifr with IBUNA caused significantly increased mortality on days 6, 7, and 9. Cuticle-degrading enzymes and EBIs may have potential to enhance the pathogenic effect of a fungal control agent against the Formosan subterranean termite.
