黄色粘虫板对番石榴园螺旋粉虱的诱捕试验

摘要

应用黄板诱集番石榴园中螺旋粉虱的成虫.结果表明:黄板以垂直悬挂在树冠中层外缘的南面诱集效果最佳,而黄板悬挂的高度以黄板的上端与树冠底部平行为最佳.%The impact of yellow sticky traps(YST)on Aleurodicus dispersus Russell was evaluated in guava fields.The results showed that the yellow sticky traps could catch more adults of A.dispersus in the middle of the south than in other three directions of guava tree canopies.And the largest amount of A.dispersus adults was trapped when the top of YST was kept at the same height of the bottom of guava tree canopy.
