寄生蜂寄主选择行为研究进展

Host selection behaviors of parasitic wasps are a comoplex and hierarchy process,which includes habitat preference, potential host location and host location. In the field,whether a parasitic wasp successfully finds its host or not is determined by many facors such as climatic conditions, host density, chemical environment, physiological states and ex-priences.This paper surveys the recent progress in the study on host selection behaviors of parasitic wasps. The following aspects are included: 1. host searching, oviposition and post-oviposi-tion behaviors of the parasitoids and the cues employed, and 2- behavioral variations of the wasps and associated factors including genotype, physiological states, experiences and learn-ing. Prospective application of parasitic wasps in pest insect control is discussed.
