[Searching behavior of Harmonia axyridis (Pallas) larvae]
Acta Entomologica Sinica 40 (2), 145-150
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) value; 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.
