[ Method] The indoor infection test and field control test of Pyemotes sp. against oriental fruit moth was carried out. The parasitic ability and activity characteristic of Pyemotes sp. were observed, and the effect of environmental factors such as humidity and temperature on the para- sitic ability of Pyemotes sp. was studied. [Result] Pyemotes sp. had good control effect on oriental fruit moth under the proper conditions; the host searching abili- ties of Pyemotes sp. were different at different temperature and humidity conditions, humidity had large impact on the activity of Pyemotes sp., while temperature had large impact on the individual activity. [ Conclusion] The result showed that Pyemotes sp. had effective control effort on oriental fruit moth.展开更多
