摘要

The prevention and control effects of Aphidius gifuensis against Myzus persicae in four major tobacco planting villages and towns in Shuicheng County were investigated from 2015 to 2016. The results showed that the parasitic rate of M. persicae before A. gifuensis release was 0. 85% in field,and that at 20 d after A. gifuensis release was 59. 49%. The incidence rate of aphid-transmitted virus disease was controlled at 0. 62%. The release of A. gifuensis increased its natural population quantity in field,and had obvious direct control effects against M. persicae. Meantime,it indirectly controlled the occurrence of aphid-transmitted virus disease to some extent.
