| 摘 要： | 本试验采用Nakamuta(1982)装置研究两种光照条件下异色瓢虫幼虫的食物搜索行为，结果表明：(1)摄食刺激均能激发搜索行为由广域型转换为地域集中型；(2)摄食时间越长，地域集中型搜索时间(GUT)值越大；(3)摄食的最后一个食饵大小决定GUT的长短；(4)光照对搜索行为有影响；(5)饥饿度对GUT的长短有一定影响。

| Abstract: | Searching behavior of the larvae of Harmonia axyridis (Pallas) was studied with Nakamuta apparatus (1982), under two illumination conditions. The results show: 1.feeding stimulus can induce a switchover of searching behavior from area-dissipated type to area-concentrated type; 2- the longer the feeding time, the higher the giving-up time (GUT) value3 3. the GUT is determined by the size of prey at the final feeding ; 4- light illumination has influence on searching behavior and 5. the degree of starvation has certain influences on GUT. |
