摘　　要：为有效防治杜鹃主要害虫杜鹃冠网蝽,选择37%高氯·马、1.8%阿维菌素、5%吡虫啉·氯氰菊酯复配乳油以及10%吡虫啉4种药剂,进行室内毒力测定及药效试验。结果表明:4种药剂对杜鹃冠网蝽均有较好的防治效果,药后5天的防治效果均达到100%,其中5%吡虫啉·氯氰菊酯复配乳油1 000倍液,药后1天、2天和3天对杜鹃冠网蝽的防效分别达到93.3%、98.9%、100%。4种药剂的毒力排序为5%吡虫啉·氯氰菊酯复配乳油>37%高氯·马>1.8%阿维菌素>10%吡虫啉。In order to control of Stephanitis pyriodes which is the main pest of Rhododendron simsii, 37% beta-cyper- methrin malathion, 1.8% avermectin, 5% imidacloprid · cypermethrin and 10% imidaeloprid were selected for toxico- logical test and laboratory experiments on Stephanitis pyriodes. The results showed that, all of the four pesticides were suit for controlling of Stephanitis pyriodes, the control effect of four pesticides were 100% after 5 days sprayed. The control effect of 5% imidaeloprid and cypermethrin mixtures EC diluted by 1 000 times were 93. 3%, 98.9% and 100% after 1 day, 2 days and 3 days sprayed respectively. The toxicity of four pesticides was 5% imidacloprid · eypermethrin 〉 37% beta - eypermethrin malathion 〉 1.8% avermectin 〉 10% imidacloprid.
