| Abstract: | In order to effectively use Dastarcus helophoroides to control Anoplophora glabripennis,the experiment was carried out in Wuwei oasis area,and the control effect was compared using different ways,at different periods,with different quantity and provenance.The results showed that there was no difference in control effect between direct release and drilling release.The control parasitism rate of D.helophoroides released in early June was 14.17 percentage point higher than that released in late September.The control parasitism rate increased with the increase of the quantity released,and the increase of parasitism rate tended to be smooth when releasing four individuals or above.There was no difference in the control parasitism rate between the provenances from Hunan and Beijing.Therefore,four D.helophoroides adults could be released per plant in early June to control A.glabripennis in Wuwei oasis area. |
