绿色威雷喷施松饵木防治松褐天牛试验

Experiments of Spraying Lyuseweilei Microcapsules on Trap Log of Pine against Monochamus alternatus

通过应用不同浓度的绿色威雷稀释液喷施松饵木进行松褐天牛林间防治试验,结果表明:1%、0.5%浓度的绿色威雷防治效果最好,株诱杀成虫分别达112.2头、112头,0.5%浓度防治成本相对较低,对下一代幼虫的控制效果达100%,处理的饵木不需进行清理就能对松褐天牛种群密度起到控制作用,在生产中应用以0.5%浓度为宜。

The experiments of spraying Lyuseweilei Microcapsules on trap log of pine against Monochamus alternatus were conducted .Result shows that ：the control effect of 1% 0 .5% concentration of Lyuseweilei microcapsules are the optimal ;trapping adult strains per tree is 112 .2 ,112 ,respectively ;the control costs of 0 .5% concentration is rel-atively low ;the control effect on next generation of larvae are 100% ;treated trap log can control the population den-sity of Monochamus alternatus without cleaning ;the suitable concentration should be 0 .5% in the production .
