摘要
明亮长脚金龟子成虫对聚灭小蠹虫生物食诱剂具有较强的趋性,平均每诱捕器诱集到的成虫数量为98.92头,最高达到211头,平均每株虫口密度由防治前61.56头降至26.13头,防治效果56.98%。聚灭小蠹虫生物食诱剂对降低明亮长脚金龟子成虫虫口数量及其对天然灌木林的危害具有一定效果。
Hoplia spectabilis adults are addicted to beetles.Each trap container can trap Hoplia spectabilis adults on average 98.92 heads and highest to 211 heads.The adult density declined from 61.56 heads per plant to 26.13 heads,making control effect 56.98%.The biological food attractant is effective to control Hoplia spectabilis.
