植物源引诱剂防治侧柏蛀干害虫野外应用技术研究

Research on Field Application Techniques of Plant-Derived Attractants for Controlling Pests of Platycladus orientalis

通过采用自行研制的林间组装式诱捕器搭配新型植物源引诱剂进行了野外应用试验。结果显示:TC-1、TC-2从引诱效果,持续时间和成本方面都比较适宜;诱捕器悬挂在主干上距地面10~50cm处效果最好;诱捕器之间水平距离50~80m为宜;诱集量与温度成正相关,与风力成负相关;三种引诱剂引诱效果远远高于侧柏饵木;塑料诱捕器诱集效果好于铁质诱捕器;同一试验地连续两年诱杀,林间虫口数减少78%。

Field application experiments were carried out by using a self-developed inter-plant traps with a new plant-derived attractant.The results show that TC-1 and TC-2 are suitable from the attracting effect,duration and cost;the trap is best to hang from the ground at 10-50cm from the ground;the horizontal distance between the traps is 50-80m.The amount of trapping is positively correlated with temperature and negatively correlated with wind force;the attracting effect of three attractants is much higher than that of arborvitae bait;the trapping effect of plastic trap is better than that of iron trap;the same experiment is trapped for two consecutive years.The number of insects in the forest decreased by 78%.
