Influence of drug form and host state on germination and infection of Beauveria bassiana

Abstract

Abstract: Under appropriate temperature condition, the infection process of Beauveria bassiana and the host death rate of host were faster in liquid treatment than in powder treatment, which was due to their different humidity. The conidia could not germinate and infect host at low atmospheric temperature (0～10℃). The development of B.bassiana in dead hosts was faster than that in living hosts. Both the hosts after low temperature treatment and the fresh hosts had the same resistance to infection. Therefore, it is unsuitable to control Dendrolimus punctatus in forests through releasing fungus in winter.

Key words: Beauveria bassiana, Dendrolimus punctatus, Infection
