摘要
研究了甜菜夜蛾性引诱剂田间不同使用方法对诱捕效果的影响。研究结果表明,低密度(0.72个/667m2)的诱捕效果好于高密度(1.60个/667m2)的诱捕效果;干式诱捕器的诱集瓶有水无水差异不大;甜菜夜蛾和斜纹夜蛾诱芯同时使用对各自的诱捕效果均有一定程度的干扰,成虫高发期差异显著,但在成虫虫口密度低的情况下差异不明显。
Trapping effect with the different use of the sex attractant of Spodoptera exigua in the field was experimented.The results showed that the trapping effect of low density installation （0.72 units/acre） was better than high density installation （1.60 units/acre）.There was no significant difference that trap bottle had water or not.Combining the S.exigua lure and Prodenia litura lure had some extent interference to their trapping effects for each other,especially in the high incidence of adult population,but no significant difference on condition that adult population density was low.
