摘要/Abstract

摘要： 目的解决高温、潮湿地区埋在地下的诱饵在黑翅土白蚁工蚁未发现前就腐烂变质的问题。方法在重庆市南岸区南山林场的樟树林内,选择4个白蚁危害严重的区域作为试验点。在每个试验点,按照L9(3⁴)正交试验设计要求,以间距5 m的方式设置9个处理,每处理各使用4包诱饵。诱饵包使用后每隔7 d观察1次,连续观察4次,记录各处理诱饵包被白蚁取食情况和腐烂程度。结果现场试验结果表明,按A₁B₃C₃(包埋材料选择樟树枯枝、埋设深度选择2 cm、覆盖措施选择土壤+农膜)方式使用的诱饵包,其被白蚁取食的比率均>75%,腐烂度均为0;按其他方式使用的诱饵包,被白蚁取食的比率<75%,且均有不同程度的腐烂。结论利用正交试验可优化诱饵包使用技术,优化得到的使用技术可大幅度降低诱饵包腐烂的风险,提高诱饵包被白蚁取食的比率,值得在生产中推广应用。

Abstract: Objective To look for a solution to the problem of rotting baits buried in soil in the areas with high temperature and moist climate before they are found by subterraneous termites. Methods Four woodlands seriously damaged by subterraneous termites in the Cinnamomun camphora forest in Nanshan Forestry Center in Nan’an District of Chongqing City were selected as the experimental sites. Based on the requirements for the design of the orthogonal experiment in L9 (3⁴), nine treatments were implemented in each experimental site. The interval distance between treatments was 5 meters with four bait bags used in each treatment area. Put in place, every bait bag was checked every 7 days. Four consecutive checks were done during the period of experiment, the amount of baits in each bag fed by termites and the rotten degree of the baits estimated. Results Field experiment results indicated that when the bait bags were applied in the mode of A₁B₃C₃, which meant that dry branches of C. camphora were used to enwrap the bait bag, which was buried 2 cm under soil and the plastic membrane and soil were covered on the bait bag, the bait bags fed by termites amounted to more than 75% with no bait bag decay at 4 weeks after application. The bait bags fed by termites was less than 75% with the bait bags having varying degrees of putrefaction when the bait bags were applied in other modes in this experiment. Conclusion The technique for application of bait bags can be optimized by orthogonal experiment. This optimization is expected to greatly decrease the risk of rotting bait bags and significantly enhance the amount of bait bags fed by termites. It is suggested that this new application technique deserve to be promoted for termite control.
