摘要： 为研究不同杀虫剂对甘蔗螟虫的防治效果及使用技术，筛选有效防治甘蔗螟虫的理想杀虫剂，采用5种杀虫剂防治甘蔗螟虫进行田间药效试验，评价分析各种农药对甘蔗螟害株和螟害节的防治效果以及对甘蔗糖分和产量的影响。结果表明，不论新植蔗还是宿根蔗，与空白对照相比，各药剂处理对甘蔗螟虫均有不同程度的防治效果，甘蔗糖分和产量均有所增加；其中5%异丙特丁硫磷颗粒剂75 kg/hm2对螟虫的防治效果最好，螟害株防治效果和螟害节防治效果分别为76.59%和87.83%，处理后甘蔗糖分和实测产量也均为最高，分别达15.72%和101382.15 kg/hm2，较对照增加0.64%和7832.40 kg/hm2；3.6%杀虫双颗粒剂90 kg/hm2次之，螟害株防治效果、螟害节防治效果、甘蔗糖分和产量分别为72.34%、84.26%、15.66%和100234.35 kg/hm2，甘蔗糖分和产量分别较对照增加0.58%和6684.60 kg/hm2。因此，在甘蔗大培土期，使用5%异丙特丁硫磷颗粒剂75 kg/hm2或3.6%杀虫双颗粒剂90 kg/hm2可有效防治甘蔗螟虫，增产增糖效果明显。

Abstract: Control effects and application techniques of different insecticides against sugarcane borers were investigated to screen out the effective insecticides controlling sugarcane borers. Bored stalk rate and bored node rate were used to evaluate the control efficacies of five insecticides in field trials. The effects of insecticide applications on sugar content and cane yield were also analyzed. The results showed that, for both plant cane and ratoon cane, comparing with blank control, the all insecticide treatments showed varied control efficacies on sugarcane borers, and sugar content and cane yield had been increased in sugarcane treated with insecticide. Among the all insecticide treatments, isopropyl- terbufos 5% GR 75 kg/hm2 showed the highest control efficacy of 76.59% in terms of bored stalk rate and of 87.83% in terms of bored node rate respectively, and after this treatment, sugar content and cane yield were up to 15.72% and 101382.15 kg/hm2 respectively, with content and yield increase of 0.64% and 7832.40 kg/hm2 compared with the control. The control efficacies with bisultap 3.6% GR 90 kg/hm2 of bored stalk rate and bored node rate were 72.34% and 84.26%, and sugar content and cane yield were 15.66% and 100234.35 kg/hm2, respectively, with content and yield increase of 0.58% and 6684.60 kg/hm2 compared with the control. It concluded that isopropyl-terbufos 5% GR 75 kg/hm2 or bisultap 3.6% GR 90 kg/hm2 at the large earthing-up stage could effectively control sugarcane borers, and bring significant increase in both sugar content and sugarcane yield.
