金斑蝶成虫访花行为及其访花活动规律

Flower Visiting Behavior and Daily Activity Rhythm of Adult Danaus chrysippus

[目的]为摸清金斑蝶访花规律。[方法]采用观察法,对金斑蝶在马利筋花序上的访花行为、访花规律和访花时间进行了调查研究。[结果]金斑蝶在6月和10月的日访花规律均为双峰曲线,最低谷都在14：00~15：00,且6月份的访花活动开始更早,结束更晚,在6月的取食平均时间极显著高于10月（P〈0.01）。[结论]温度是影响金斑蝶访花活动规律的主要因素。

[Objective] The research aimed to find out the flower visiting regularity of adult Danaus chrysippus L. [Method]We used the observation method to study flower visiting behavior,activity rhythm and feeding time of Danaus chrysippus. [Result]The daily activities of Danaus chrysippus appeared double-peak type in June and October,in which the crest was reached at 14： 00-15： 00. The beginning of the flower visiting activities of Danaus chrysippus in June was earlier than that in October,but it was opposite in the end of the activities. The feeding time in June was significantly longer than that of in October（ P 〈0. 01）. [Conclusion]The temperature was the main factor that affected the activity of the flower of Danaus chrysippus.
