五加异个木虱越冬代成虫田间动态与防治技术

The field dynamics and control techniques of Heterotrioza acanthopanaicis (Li) overwintering adult

五加异个木虱是危害短梗五加的专食性害虫,为掌握该害虫越冬代成虫的田间动态和防治技术,使用不同手段处理地面并悬挂黄色粘虫板诱捕成虫。结果显示:与未悬挂粘虫板的地块相比,悬挂粘虫板的自然状态、清理地面、覆盖地膜3种处理地块五加异个木虱虫瘿数量分别降低82.23%、93.19%、98.50%;在悬挂粘虫板的3种处理中,以覆盖地膜处理的防治效果最好。建议于越冬代成虫活动前,在田间清理地面枯枝落叶并覆盖地膜,以实现五加异个木虱的无公害防治。

Heterotrioza acanthopanaicis(Li)is a host specificity pest of Acanthopanax sessiliflorus.In order to research the field dynamic changes of overwintering adults of H.acanthopanaicis and its control techniques,different ground treatments were conducted in field and yellow sticky cards were hung to trap adults.The results showed that,comparing with the treatment that did not hang the sticky card,the number of cecidium in the three treatment plots decreased by 82.23%,93.19%,and 98.50%,respectively.Among the three treatments of hanging the sticky card,the mulching treatment presented the best control effect.Therefore,cleanning up the ground litter in the field and covering the mulch before the activity of overwintering adults is a effective method for non-polluting control of H.acanthopanaicis.
