利用粘胶黄板防治梨茎蜂试验

Study on Janus piri Control by Using Yellow Sticky Traps

为探索利用生态、高效、经济、安全的防治方法控制梨茎蜂的危害，于3月下旬梨茎蜂开始羽化时，在梨树上悬挂粘胶黄板，分别悬挂120张/hm2、150张／hm2，平均防效在94．28％～96．44％。试验结果表明：在梨园悬挂粘胶黄板可有效控制梨茎蜂的危害。

When adult Janus piri emerged in late March, 120 or 150 yellow sticky traps were hung every hn＇l2 in the pear orchard. The average control efficiency reached 94.28%-96.44%. It was effective to use yellow sticky traps to control the harm of Janus piri in pear orchards.
