防治苗圃害虫是保护苗木和发展育苗事业的重要环节。从1971年开始,我省洪洞、山阴、阳高等苗圃进行了黑光灯诱杀苗圃害虫防治试验。实践证明,对于有趋光性的害虫,灯光诱集,集中扑杀,既经济,收效又大,能把大量雌虫消灭在产卵之前,大大减轻危害。在较大的范围内,有计划地布点设置黑光灯能为虫情测报提供有用的资料和数据。现将初步试验结果介绍如下:
Prevention and control of nursery pests is to protect the nursery stock and develop an important part of breeding. From 1971 onwards, Hongdong, Shanyin, Yang and other nurseries in our province were black-light trap nursery pest control experiments. Practice has proved that for phototaxis pests, light trapping, curtailment, both economic and effective large, can eliminate a large number of females before spawning, greatly reducing the harm. In a larger area, the planned setting of black light can provide useful information and data for insect detection. Now the preliminary test results are as follows:
