摘要
研究得出,这种新害虫属同翅目介壳虫科,对柳树的危害严重。该虫以受精的雌成虫在柳树的树皮裂缝中越冬。用10%吡虫啉可湿性粉剂2000倍液树干喷雾防治该虫效果最佳,药后7d防效达最高值;其次是1%阿维虫清乳油2000倍液,二者虫口减退率均达92%以上。
The new pest thatdamages causes to willows belongs to diaspidoidae,Homoptera Coccidae. The female adult overwinters in the crack of willowsq bark. The most effecfive treatment is to spray the trunk with 10 % WP imidacloprid 2000-fold and the highest efficaiency is 7d later ;the second is 1 % EC emulsifiable solution 2000-fold.
