Survival of Beauveria bassiana (Deuteromycetes: Moniliales) conidia on cadavers of cowpea pests stored outdoors and in laboratory in Brazil
Environmental Entomology 15 (3), 642-647
Abstract: Cowpea pest cadavers with Beauveria bassiana (Balsamo) mycoses were stored outdoors both under exposure to sunlight and rainfall and under protected conditions, and in the laboratory at 4 and 27°C over prolonged intervals. Conidia on cowpea curculio adults stored outdoors under protected conditions remained stable (i.e., without loss of viability) for at least 16 weeks and with only a slight decline in germinative ability for up to 24 weeks. Under the same outdoor conditions, Conidia on chrysomelid beetle cadavers also survived well. In contrast, infected cowpea pest cadavers stored outdoors under direct exposure to rainfall and sunlight lost most of the conidia from their cuticles within 2 weeks; however, among the conidia that remained on the cadavers no decline in viability could be detected. The virulence of B. bassiana strains to their host insects was not correlated with the stability of conidia on host cadavers stored outdoors.
