摘　　要：在室内采用饲喂法进行了4种药剂防治女贞球象成虫的药效试验,结果为:在25g·L-1敌杀死EC、10%吡虫啉WP、80%敌敌畏EC、菜乐安WP等不同稀释倍数的处理中,80%敌敌畏EC 1 000、700、500倍液处理对女贞球象成虫药后5d防效分别为96.6%、82.7%、93.1%,其次菜乐安WP 500倍液,药后5d防效可达79.3%。在25g·L-1敌杀死EC和10%吡虫啉WP的不同稀释倍液中,药后5d最高防效仅达48.3%。80%敌敌畏EC和菜乐安WP对女贞球象成虫室内防治效果较好。The biometric test of four pesticides to the adults of Stereonychus angulicollis Voss was carried out by feeding leaf dip method in laboratory.Deltamethrin 25g·L-1EC,imidacloprid 10%WP,dichlorvos 80%EC and Cai Le-an WP were tested at different concentrations.The results showed that control effect of dichlorvos 80%EC diluted multiples of 1 000、700、500were 96.6%、82.7%、93.1% on the fifth day after treatment.Secondly,control effect of Cai Le-an WP diluted 500 times was 79.3%on the fifth day after treatment.Control effect of deltamethrin 25g·L-1 EC and imidacloprid 10%WP was only 48.3%.The dichlorvos 80%EC and the Cai Le-an WP have a good control effect on adults in laboratory.
