摘　　要：小绿叶蝉对碧桃的危害严重,不但降低了观赏价值,而且影响其生长发育。本试验使用4.5%高效氯氰菊酯1500倍、1.0%蚜螨正反杀绝2000倍、5%蚜虱统杀1500倍、10%克蚜灭实3000倍、22%天杀星乳油800倍这五种药剂进行了防治碧桃小绿叶蝉的药效试验,试验结果表明:4.5%高效氯氰菊酯1500倍、1.0%蚜螨正反杀2000倍、10%克蚜灭实3000倍在施药后3d,校正防效分别达89.01%,90.95%,79.40%,可在碧桃小绿叶蝉防治时进行使用。Empoasca flavscens is harmful to Prunus persica seriously. Five pesticides such as toxicity of 4.5% beta cypermethrin 1,500 times, 1.0% aweigaolu 2,000 times, 10% imidacloprid 3,000 times, 5% aphis louse -killing 1,500 times, 22% phoxim -alphacypermethrin emulsifiable concentrate 800 times were applied on citrus to compare the effect of controlling Empoasca flavscens. The results showed that the control effect of 4.5% beta - cypermethrin 1,500 times was 87. 45%, 1.0% aweigaolu 2,000 times was 90.82%, 10% imidaeloprid 3,000 times was 79.40%. The control effect of aweigaolu 1.0% and 4.5% beta - cypennethrin were the best pesticides.
