摘要
【目的】探索和寻求高效安全的甘蔗螟虫绿色防控技术,推进甘蔗病虫绿色防控,构建资源节约型、环境友好型甘蔗病虫可持续治理体系。【方法】2016年选用螟虫性诱剂新型诱捕器、阿维菌素·苏云金杆菌和虫酰肼等生物制剂进行田间试验研究。【结果】在甘蔗生产上,以螟虫性诱剂新型诱捕器6 hm^(–2)+0.05%阿维菌素·100亿活芽孢/g苏云金杆菌(Bt)可湿性粉剂1.8 kg/hm^2或螟虫性诱剂新型诱捕器6 hm^(–2)+200 g/L虫酰肼悬浮剂1.5 L/hm^2结合使用最佳,宜在3月初安装螟虫性诱剂新型诱捕器,4月初按每公顷生物制剂用量对水900 kg稀释后均匀喷洒蔗株,对螟害枯心率和螟害株率的防效分别达69.98%和49.09%以上,显著优于对照农药3%杀虫双颗粒剂90 kg/hm^2的防效。【结论】螟虫性诱剂新型诱捕器与生物制剂阿维菌素·苏云金杆菌或虫酰肼结合使用是防控甘蔗螟虫理想的绿色防控技术模式,与其他技术轮换或协调使用,可延缓抗药性产生和发展,值得在蔗区大面积推广应用。
[Purposes]In order to explore and seek high-efficiency and safe green control techniques on sugarcane borers, promote green control of diseases and pests of sugarcane, build a resource-conserving, environmentally friendly and sustainable governance system of diseases and pests of sugarcane.[Methods]In 2016, new sex pheromone trap of sugarcane borers, Abamectin·Bacillus thuringiensis（Bt） and tebufenozide were selected and applied in field trials. [Results]The use of new sex pheromone trap of sugarcane borers（6 hm^–2） in combination with 0.05% Abamectin·10 billion active gemma/g Bt WP（1.8 kg/hm^2） or new sex pheromone trap of sugarcane borers（6 hm^–2）in combination with 200 g/L tebufenozide SC（1.5 L/hm^2） were the best in the sugarcane production.New sex pheromone trap of sugarcane borers should be installed in early March, and biological agents were mixed with water 900 kg/hm^2 and sprayed evenly sugarcane plants at the beginning of April, and the control effect of dead heart rate and bored stalk rate could be more than 69.98% and 49.09% respectively, and it was superior to the control pesticide 3.6% bisultap GR（90 kg/hm^2）. [ Conclusions]The new sex pheromone trap of sugarcane borers in combination with Bt or tebufenozide is the optimum mode of green control techniques on sugarcane borers. When it was alternately or coordinately used with other technology, it could delay the emergence and development of drug resistance, and it was worthy of widespread popularization and application in sugarcane area.
