Description:
The philosophy of this practice is a conservative one. This laboratory bioassay is designed to evaluate potential pathogenicity of a fungal agent on a standard predatory mite, Metaseiulis occidentalis (Nesbitt), under conditions intended to maximize the virulence of the fungus and the susceptibility of the predatory mites. This practice describes procedures to evaluate the lethal effects of fungal agents to adult female predatory mites, M. occidentalis, via direct exposure. Results measure the pathogenicity of a fungus to the preditory mites under controlled conditions. The bioassay has not been attempted with either viral or protozoan preparations.
