摘要
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.
