摘要
【目的】为了探索甘蔗条螟性诱剂诱杀防治的田间使用技术,确定最优防控处理面积和防控时间。【方法】通过实施不同面积比例的甘蔗条螟性诱剂诱杀试验,比较3种布盆密度条螟诱杀处理效果,分别从条螟诱杀蛾量、螟害株率和防治成本3方面进行评价各处理的优劣。【结果】试验结果显示:C处理(1 hm2/盆)和B处理(0.67 hm2/盆)诱杀蛾量差异不显著,但与A处理(0.33 hm2/盆)差异显著,B处理和A处理差异不显著;A处理和B处理的螟害株率相对防效差异不显著,但2处理与C处理差异显著;防治成本由高到低排列为A处理(0.33 hm2/盆)>B处理(0.67 hm2/盆)>C处理(1 hm2/盆);综合评价认为B处理为较优条螟诱杀防治处理。
The paper was to study the sex pheromone mass trapping technology to select the best application rate and application time. The different application rates of sex pheromone for controlling the stalk borer, Proceras venosatus were tested. Test A, Test B, and Test C were evaluated in numbers of stalk borers trapped, sugarcane damage rate and management costs. The result showed that test C was not significantly different with test B, but was significantly different with test A. Test B and test A were not significantly different. In sugarcane damage rate, test A was not significantly different with test B, but both were significantly different with test C. The management costs were different in these three tests. In summary, Test B was recommended for general use for controlling stalk borer, Proceras venosatus.
