An Effective Method for Biological Control of Anoplophora glabripennis （Coleoptera: Cerambycidae） by Using a Vector Mite, Pyemotes moseri （Acarina: Pyemotidae）, Carrying Insecticidal Fungi

【Objective】 The aim of this study was to develop a new method to transmit entomopathogenic fungi by a biological vector, Pyemotes moseri, to biologically control the long-horned beetle, Anoplophora glabripennis, efficiently.【Method】 Pyemotes combined with entomopathogenic fungi spores was used as an approach to spread the entomopathogenic fungi spores into the larval galleries of the long-horned beetle for effective infection of the larvae. An outdoor simulated control test was carried out by using one meter damaged poplar trunks with the trunk base planted in soil and covered with mesh net. Each treatment was triple replicates and each replicate was made of ten damaged poplar trunks. Four treatment groups were set up, and the release unit in four treatments respectively included Pyemotes and Beauveria bassiana,Pyemotes and Metarhizium anisopliae, B. bassiana and M. anisopliae, Pyemotes. Blank control was sterile without mites in the release unit. The number of frass holes and emergence holes of long-horned b
