| 摘 要： | 云南木蠹象是鞘翅目象甲科的一种蛀干害虫,危害健康云南松。2002年在贵州威宁暴发危害,当时除了人工清理枯死枝条、枯死植株外,无有效防治措施。在羽化期喷施1000倍40%速扑杀乳油两次后,云南木蠹象的危害指数平均下降11.08,防治效果可达50.6﹪。通过试验,我们认为速扑杀可用在虫源地控制虫口密度,连续2￣3年使用可以抑制虫害蔓延扩散。

| Abstract: | Pissodes yunnanensis Langor et Zhang is a serious insect pest of Yunnan pine(Pinus yunnanensis),and its control measures are limited,with clipping operations to remove infested leaders being the only effective way.In the period of adult emergence,40% methidathion was twice applied.The results showed that the average pest damage index decreased by 11.08,and the control efficiency was up to 50.6%.It was suggested that mehidathion be applied for consecutive 2-3 years in pest source regions to prevent the sprea... |
