摘要
应用黄板诱集花菜和菜豆田中烟粉虱成虫。结果表明 :花菜田中东西向放置的黄板诱集效果优于南北向 ,搭架的菜豆田中顺行向优于垂直行向 ;黄板放置高度花菜田以黄板下端略高于菜叶顶部为宜 ,搭架的菜豆田以架中部为宜 ;诱集时间以 11时至 15时为佳。
The experiments of impact of yellow trap to sweetpotato whitefly was made in vegetable field. The results showed that the yellow traps can catch more adults of whitefly in directing west east than north south in Cauliflower field, and more in parallel to row than upright in Kidney bean field. And more whitefly was caught during the midday hours. The best place for yellow traps is little up to the vegetable leaves in Cauliflower field and in the middle of stand in Kidney bean field.
