Abstract

Making use of Bethylidae carrying pathogens to prevent and control the longicorns could play advantage of active search of Bethylidae and strong pathogenicity of pathogens,better than releasing Bethylidae only or spraying microbial inoculum. However, it was necessary to ensure that the carrying pathogens would not significantly affect the Bethylidae' host search ability. In order to use Scleroderma sichuanensis carrying pathogens to prevent and control Monochamus alternatus,this paper measured the virulence of the conidial powder and spore suspensions of four strains of pathogens on S. sichuanensis. The results showed that the mortality rate of the powder spores in S. sichuanensis was higher than that of the suspension spores. When spraying spore suspension, the cumulative mortality of four strains increased along with the increasing concentration. For S. sichuanensis, the virulence of Beauveria bassiana was relatively higher than that of Metarhizium anisopliae, and the lethal rate of B. bassiana was also higher than that of M. anisopliae. Research results could provide some basis data for the selection of strains and development of microbial inoculum which was useful for S. sichuanensis carrying pathogens to prevent the M. alternatus.
