异色飘虫雄成虫的食饵搜索行为

Bait-searching behavior of Hormonia axyridis male imagoes

研究两种光照条件下异色飘虫雄成虫的食饵搜索行为．结果表明，５种刺激均 能激发搜索行为由广域型转换为地域集中型；摄食时间越长，ＧＵＴ值越大；摄食的最后一 个食饵大小决定ＧＵＴ的长短；光照强度对搜索行为影响不大．

The bait-searching behavior of Hormonia axyridis male imagoes was studied under two illuminations. The results showed that each of 5 feeding stimuli could arouse searching behavior from area-dissipated to area-concentrated type. The longer the feeding time, the bigger the giving-up time(GUT) which was determined by the size of the last consumed prey. The effect of illumination intensity on searching behavior was not significant.
