摘　　要：[目的]探讨20％康宽悬浮剂、30％度锐悬浮剂、20％速杀特3种新型杀虫剂对甘蔗产量和品质性状的影响及对甘蔗螟虫的防治效果,以期筛选出适宜广西蔗区的有效防治甘蔗螟虫的新型药剂,为指导大田生产提供参考.[方法]采用叶面喷施方法,进行了20％康宽150 ml/hm2、30％度锐150 ml/hm2、20％速杀特1 500 ml/hm2 3种新型杀虫剂防治甘蔗螟虫的田间药效试验,以清水为对照.[结果]施用3种杀虫剂后第23天的枯心苗率防治效果为41.43％ ～48.57％;第183天的螟害节率、螟害株率、死尾株率防治效果分别为21.49％ ～24.47％、7.48％～9.14％、8.72％ ～11.05％;甘蔗收获时的有效茎数比对照增加了6.19％ ～ 8.18％,甘蔗蔗糖分提高了0.68～1.00个百分点.3种杀虫剂处理对甘蔗螟虫防治效果和对甘蔗产量及品质性状的影响差异均不显著.[结论]3种杀虫剂对甘蔗螟虫均具有良好的防治效果,且以防治枯心苗率的效果最好;3种杀虫剂间防治效果差异不显著,均可作为防治甘蔗螟虫的新药之选.[ Objective] Control efficacy of 3 pesticides （20% Chlorantraniliprole SC, 30% Chlorantraniliprole Thiamethoxam SC, and 20% Avermectin） for sugarcane borer was explored to figure out suitable chemicals for controlling sugarcane borer in sugarcane producing regions of Guangxi, and provide references for field production. [ Method] Spray 20% Chlorantraniliprole （ 150 ml/hm2 ）, 30% Chlorantraniliprole Thia- methoxam （ 150 ml/hm2 ）, and 20% Avermectin （ 1 500 ml/hm： ） for field test, and clean water as the control group. [ Result] After applying the 3 pesticides, control efficiency for dead heart seedling 23 days later is 41.43% - 48.57%, control efficiency for borer-damaged node, borer- damaged plant, and dead end plant is 21.49% -24.47%, 7.48% -9.14%, 8.72% -11.05% 183 days later; the harvest effective stems in- crease by 6.19% - 8.18% from the control group, sucrose increases by 0.68% - 1.00%. Influence of the 3 pesticides on growth of sugarcane shows no obvious difference. [ Conclusion ] The 3 pesticides show high efficiency in controlling sugarcane borer, especially dead heart seedlings; and the efficiency shows no obvious difference, so all of them can be applied as the new chemical for controlling sugarcane borer.
