光肩星天牛成虫在寄主选择过程中的判断机制研究

为掌握光肩星天牛成虫对寄生树种如何进行识别选择，作者进行了对比、分析成虫栖息、取食和产卵过程中在不同树种间的活动行为表现，以及成虫对寄主树木气味或味迹的嗅觉和味觉测定等项研究．结果表明，光肩星天牛成虫在寄主选择过程中，非接触性的嗅觉识别判断不起主导作用；成虫对寄主的选择是在不断的活动过程中，主要通过触角和口须上的化感器接触感应，在味觉和嗅觉等的共同参与下完成的．

Distinguishing Mechanism in the Selection of Hosts of Anoplophora glabripennis (Motsch.)

In order to realize how the A. glabripennis adults identify the host tree species,the behaviors in the inhabitant, eating and oviposition progress of the adults among the variable trees were compared and analysed, and their odor or flavour trails by olfactory and gustatory test on host trees were carried out as well.The results show that the distinguishing ability of the A.glabripennis adults by non\|touching olfaction estimation is not a dominant factor during the host selection. The adult's selection to hosts is mainly affected by the chemical inductors on the antenna and oral palpi, and finished with the feeling, gustation and olfaction actions together.
