不同防治方式对天牛的防治效果研究

为明确不同防治方式对法国梧桐蛀干性害虫星天牛的防治效果并探究最佳防治措施,分别采用物理防治(人工挖虫)、药剂打孔注射、药剂毒签堵孔、药剂喷淋及“物理防治+药剂打孔注射+药剂喷雾”组合防治的方法,进行法国梧桐天牛防治试验,结果表明：本文通过比较当前主要防治措施的防治效果,结果表明采用“物理防治(人工挖虫)+ 8%高效氯氰菊酯微囊悬浮剂喷洒树干+10%甲维.吡虫啉可溶液剂打孔注药”相结合的方式防治天牛,效果稳定,防治后15天、1年、2年虫口减退率均达到95%以上。

Control effect of different control methods on longhornedbeetles

To explore the best prevention and control measures on longhornedbeetles of platanus, different control methods as the physical control (artificial digging worm), injection of chemicals, hole killing by chemical poison, spraying of chemicals, and combination of physical control and pesticide injection plus pesticide spray were practiced to control the disease. By comparing the control effects of the main control measures, the results showed that the control effect of the combination of "physical control (artificial digging insect) + 8% beta cypermethrin microcapsule SC + 10% Emamectin . imidacloprid soluble agent drilling injection" was used to control longicornbeetles, and the control effect was stable. After 15 days, 1 year and 2 years, the population decline rate reached more than 95%.
