青海祁连地区四川绢蝶成虫习性的初步观察

The observation of the adult habits of Parnassius szechenyii at Qilian mountains in Qinghai

为了了解四川绢蝶的生活习性,2009年6月至8月对青海省祁连地区的四川绢蝶Parnassius szechenyii Frivaldszky进行了实地调查研究。研究结果表明,该绢蝶喜欢在位于山谷到山顶间的中偏上部飞行活动,并对树林和人工破坏的区域有着很强的回避作用;雄性绢蝶的被捕捉机率要远大于雌性的;绢蝶一般喜欢在无风、阳光充足、气温较高的天气活动,其年活动最高峰大约在每年的7月中旬,日活动最高峰在每天的13:00左右。

The habits of adult Parnassius szechenyii Frivaldszky were investigated from June to August 2009 in the Qilian mountains,Qinghai province.The results show that this butterfly usually flies from above the middle of valleys to hilltops on windless,sunny and warm days,and avoids forest and human-modified environments.The capture sex-ratio was male-biased.P.szechenyii was most conspicuous in July during the breeding season between 12：30—13：00.
