摘 要:选用5种杀虫剂对黄圆蹄盾蚧及其寄生性天敌影响进行了实验室和田间试验,试验结果表明:所选杀虫剂对黄圆蹄盾蚧的成虫和若虫的防效均在50%以上,最高可达93.3%,对若虫的防效好于成虫。在实验室防治成虫效果最好的药剂是25%β-双高效氯氰菊酯和40%乐果,其次是48%乐斯本乳油;而防治若虫效果最好的药剂是48%乐斯本乳油和25%β-双高效氯氰菊酯,其次是40%乐果;此外,所选的杀虫剂对黄圆蹄盾蚧的寄生性天敌昆虫均有不同程度的毒性。AonidieUa citrine was a main pest insect with wild host plants in all over the world. In this experiment,5 pesticides were used to studios the control effect on the insect and the influence of the pesticide on its the natural enemies was also investigated. The results indicated that the control effect of all pesticides on nymphae or adult was over 50 % ,and the best one was around 93.3 % ,and the results suggesting the effect on the nymphae was better than on the adult. The best effect of pesticide on the adult,in labrotory condition,was 25 % β-cyper- methrin EC and 40 % dimethcate EC,the following one was 48 % chlorpyrifos EC. On the nymphae,the best effect was 48 % chlorpyrifos EC and 25 % β-cypennethrin EC,the following one was40 % dimethoate EC. However,all the experimental pesticides had certain toxicity to the parasitic natural enemies.
