2、诱作用最强的是苯乙醛和乙酸苯甲酯组成的二元混合物,其次是苯乙醛和乙酸苯甲酯单剂。玉米螟成虫主要对二元混合物、苯乙醛和苯乙醇具有趋性。单纯的苯乙醛样品诱捕到的甜菜白带螟数量最多,显著优于苯乙醛和乙酸苯甲酯组成的二元混合物,肉桂醛和苯乙醇对甜菜白带螟也有很强的引诱作用。总体来看,苯乙醛和乙酸苯甲酯以165L:335L混成的二元配方成型于琼脂胶,有望成为大豆田鳞翅目害虫生态治理的一项有潜力的替代性措施。关键词:大豆田;鳞翅目害虫;花香气味;诱捕中图分类号:S435.651文献标志码:A文章编号:1004—3268(2013)11—0094—04TrappingEffectofCommonFlo
