The pathogenicity of Tetranychus cinnabarinus was studied by using BtR05 strain. Its acaricidal activity was confirmed to prepare BtR05 suspending agent (BtR05 SC). This suspending agent was used to make the indoor toxicity test on the young, nymphae and adult T.

方法］使用BtR05菌株对朱砂叶螨进行致病性研究，确定其杀螨活性后，制备了BtR05悬浮剂，并使用该悬浮剂对朱砂叶螨的幼螨、若螨和成螨进行了室内毒力测定。
