摘　　要：将单一释放烟蚜茧蜂(Aphidius gifuensis)、异色瓢虫(Leis axyridis)以及两者结合释放防治烟蚜(Myzus persicae)与化学药剂和空白对照进行防治效果的调查比较。结果表明,烟蚜茧蜂和异色瓢虫结合释放防治烟蚜效果好于单一释放防效,其后期防效好于化学药剂防治烟田。第一次处理后25 d,综合防效达75.14%,第二次处理后35 d,防效为75.01%。The control effects of single or combined release of Aphidus gifuensi and Leis axyridis against Myzus persicae was investigated and compared with chemical control and blank control.The results showed that the control effect of combined release of A.gifuensis and L.axyridis was better than single release;and was even better than chemical control at late period.25 d after the first treatment,the control efficiency of combined release was up to 75.14%;and at 35 d after the second treatment,the control efficiency was 75.01%.
