Abstract:
Several classes of surfactants/foaming agents were screened for compatibility with blastospores of Paecilomyces fumosoroseus. The surfactants were assayed to determine their influence on the rate of germination, viability and conidia production by the blastospores. Surfactants compatible with blastospores were then assayed for their foam forming properties using a commercially available foam generator. These tests identified keratin hydrolysate as the only suitable surfactant in terms of biocompatibility and foam forming properties. Laboratory bioassays were conducted to determine the effect of keratin hydrolysate on the efficacy of blastospores against Formosan subterranean termites. The results showed keratin hydrolysate increased the efficacy of P. fumosoroseus and suggest that this foam formulation of P. fumosoroseus may be useful in controlling Formosan subterranean termites.
