摘要
试验测定了8种常用杀虫剂对双斑恩蚜小蜂成虫、蛹及寄生率的影响。结果表明,不同杀虫剂对双斑恩蚜小蜂不同发育阶段的影响不同,其中,除灭蝇胺外(死亡率为3.2%),双斑恩蚜小蜂成虫对各类杀虫剂均比较敏感,死亡率较高;蛹期相对安全,除哒螨灵造成蛹91.7%死亡外,其它药剂处理后,蛹的羽化率均在25%以上。另外,药剂处理后,对天敌后期寄生率及种群增殖都有不同程度的影响。
The effects of 8 pesticides on adults,pupae and parasitic rate of Encarsia bimaculata Heraty et Polaszek was studied.The results showed that different pesticides had different influence on Encarsia bimaculata Heraty et Polaszek at different stages.Except cyromazine（its mortality rate was 3.2%）,the adults were more sensitive to the other pesticides with high mortality.Pyridaben caused higher mortality of E.bimaculata pupae（91.7%）,and the other pesticides led to low mortality（survival rate up to 25%）.The pesticides also had different effect on the parasitic rate of the late stage of E. bimaculata and population multiplication.
