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。
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.
