目的白蚁监控喷粉技术是环保型白蚁防治新技术,具有极大的推广价值和应用前景。明确白蚁监控喷粉技术现场控制白蚁的效果,以期为全国白蚁防治行业推广应用该技术提供必需的基础信息。方法采用小范围灭巢试验和大规模现场应用试验两种形式,在全国有代表性的地区研究白蚁监控喷粉技术对白蚁巢群的杀灭效果和目标区域整体蚁害的控制效果。结果小范围灭巢试验时对28个乳白蚁巢群和50个散白蚁巢群用0.5%氟虫腈粉剂进行喷粉处理,共有17个乳白蚁巢群和30个散白蚁巢群被消灭,11个乳白蚁巢群和20个散白蚁巢群的白蚁未完全消灭,但个体数量大幅度减少。杀灭白蚁巢群所用药量乳白蚁为5~10 g/巢,散白蚁为3~5 g/巢。大规模现场应用试验时防治面积共2 510 879 m2,安装白蚁监测控制装置27 005套,共有2333套装置监测到白蚁,对其中2121套装置内的白蚁用0.5%氟虫腈粉剂进行处理,结果1919套装置内再无白蚁活动,蚁害率下降了90.44%。结论白蚁监控喷粉技术可对一定区域内的白蚁危害进行有效控制。
The purpose of termite monitoring dusting technology is environmentally friendly termite prevention and control of new technologies, with great promotional value and application prospects. Clear termites monitoring duster on-site control of termite effect, with a view to the national termite prevention and control industry to promote the use of the technology to provide the necessary basic information. Methods The test of small-scale nest-killing test and large-scale field application test were carried out to study the killing effect of termite monitoring and control dusting technology on the termite nest population and the control effect of the total ant damage in the target area in the representative areas of China. Results A small range of nesting test 28 pairs of termites nest and 50 groups of scattered termite nest sprayed with 0.5% fipronil powder, a total of 17 termites and 30 groups of termites nest were destroyed, Termites of 11 white termite nests and 20 white termite nests were not eliminated completely, but the number of individuals was greatly reduced. The amount of termites used to kill termite nests is 5 to 10 g / nest, and 3 to 5 g / nest for termites. Large-scale field application test control area of a total of 2 510 879 m2, the installation of 27,500 sets of termites monitoring and control devices, a total of 2333 sets of devices to monitor termites, of which 2121 sets of termites 0.5% fipronil powder treatment, the results There were no termites activities in 1919 sets of equipment, and the incidence of ant damage decreased by 90.44%. Conclusion Termite monitoring of dusting technology can effectively control termite damage in a certain area.
