为筛选防治杜鹃冠网蝽的无公害农药,进行了6种农药不同浓度的叶面喷雾防治药效试验.结果表明,施药后7d,10％氟铃·毒死蜱EC、5％阿维菌素EC 500倍稀释液、1000倍稀释液与1500倍稀释液防治效果间有极显著差异,2.5％溴氰菊酯EC、2.5％吡虫啉EC、2.5％高效氯氟菊酯EW、4.5％高效氯氟菊酯EC 2000倍稀释液、2500倍稀释液与3000倍稀释液防治效果间有极显著差异.6种农药均可用于防治杜鹃冠网蝽,各农药的最佳用药浓度为:10％氟铃·毒死蜱EC 1000倍稀释液,5％阿维菌素EC 500倍稀释液,2.5％溴氰菊酯EC、2.5％吡虫啉EC、2.5％高效氯氟菊酯EW、4.5％高效氯氟菊酯EC 2500倍稀释液.%In order to choose harmless pesticide spraying to control of Stephanitis pyriodes,experiments with six harmless pes-ticides in different concentrations were conducted. The test result indicated that 7 days after treated with pesticides,there were significant differences in 10% Hexaflumuron-chlorpyrifos EC, 5% Abamectin EC diluted 500 times, 1 000 times and 1 500 times, 2.5% Deltamethrin EC, 2.5% Imidacloprid EC, 2.5% Betacypermethrin EW, 4.5% Betacypermethrin EC diluted 2 000 times, 2 500 times and 3 000 times. Besides, six pesticides could be used to control Stephanitis pyriodes,and the best con-centration for them were: 10% Hexaflumuron-chlorpyrifos EC dilute 1 000 times, 5% Abamectin EC diluted 500 times, 2.5% Deltamethrin EC, 2.5% Imidacloprid EC, 2.5% Betacypermethrin EW, 4.5% Betacypermethrin EC diluted 2 500 times.
