Abstract: 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.

Key words: Hormonia axyridis, Male imagoes, Searching behavior, Larix gmelinii, spatial distribution pattern, scale, Betula platyphylla
