棉铃虫成虫趋光行为的初步研究

Preliminary Study on the Phototaxis Action of the Moth of Cotton Bollworm

通过1998-2002年对棉铃虫(HeliothisarmigeraH櫣bner)成虫趋光行为的研究,初步明确了棉铃虫蛾对诱虫光源具有一定的趋性,个体的平均上灯概率约为45 0%～63 3%;当同时存在不同的诱虫光源时,上灯有一定的选择性,选择适当的诱虫光源可以提高上灯概率;个体是否上灯并不确定,主要可能取决于其当时的复眼转化状态。

Based on the preliminary study results from 1998 to 2002, the pototaxis actions of the moth of cotton bollworm were reported in this paper. The results indicated that the moths of this pest have determinate tropism to trapping light, and the amount of the trapped moth was 45.0%～63.3% in total. The moths would choose the specifical light when there were some different trapping lights, so the highefficiency would be developed. As the transformation state was different, the moth would be trapped or not. 
