摘　　要：对印楝素、桉油精和氯噻啉3种新型药剂防治小贯小绿叶蝉[Empoasca(Matsumurasca)onukii]的田间药效进行了试验。结果表明,3种药剂对小贯小绿叶蝉均有一定的控制效果。其中,0.3%乳油印楝素250倍稀释液防效最低;5%可溶液剂桉油精300倍稀释液防效较好,药后3 d校正防效达66.92%,药后7 d校正防效为57.72%;10%可溶性粉剂氯噻啉750倍稀释液防治速效性和持效性都较好。试验期间各处理未见对茶树生长产生不良影响,安全无药害。印楝素和桉油精作为生物农药,对环境友好,可与其他化学药剂轮换使用,以延缓抗药性的产生。The field efficacy of three new agents of azadirachtin,eucalyptol and chlorothiazide on Empoasca(Matsumurasca)onukii was studied.The results showed that the three agents had certain control effects on E.onukii.Among them,0.3%emulsifiable azadi⁃rachtin 250 times liquid had lower control effect;5%solution eucalyptus oil 300 times liquid had better control effect,the control ef⁃fect on the 3th day after treatment was 66.92%,and the control effect on the 7th day after treatment was 57.72%.The 10%soluble pow⁃der chlorothiazolate 750 times solution had good control effect.During the test,each treatment did not have an adverse effect on the growth of tea trees,and it was safe and harmless.Azadirachtin and eucalyptol are biological pesticide,and are environmentally friend⁃ly and could be used interchangeably with other chemical agents to delay the development of drug resistance.
