摘要
在梨园悬挂9种颜色粘虫板诱杀梨茎蜂以筛选诱捕效果最佳颜色,并比较其不同悬挂时间、高度、密度的诱杀效果。结果表明:杏黄色粘虫板诱捕效果最好,最佳悬挂时间是3月25日至4月10日左右,最佳悬挂高度为树冠中部,最佳悬挂密度每667m230张。
Sticky traps of 9 different colors were hung in the pear orchards to trap Janus Piri and the hanging time, height and density were studied. The result showed the apricot sticky trap was the most effective. The optimum hanging time was on about 25 March and 10 April. The optimum hanging height was the middle of the tree crown and the optimum hanging density was 30 traps per 667 m2.
