摘要
对贵州省黄槐决明的主要访花昆虫种类、访花行为以及日活动规律进行了调查研究。结果共观察到15种访花昆虫,其中膜翅目种类最多。根据访花昆虫访花频次及行为观察,明确了黑足熊蜂与淡脉隧蜂是其主要传粉蜂;黑足熊蜂的平均访花频率大于淡脉隧蜂,且差异达到了极显著水平,传粉效果好于淡脉隧蜂。7:00~7:30为黑足熊蜂的访花高峰期,此时采粉积极,随着时间推移,访花蜂次逐渐减少;淡脉隧蜂的访花高峰晚于黑足熊蜂。
The main flower-visiting insect species of Cassia surattensis were investigated in Guizhou,and their foraging behaviors were studied.Study results showed that 15 species of visiting insects were observed,among which most of insects belonged to Hymenoptera.The main pollinators of Cassia surattensis were Bombus atripes and Lasiglossum sp.The average flower-visiting frequency of Bombus atripes was significantly higher than that of Lasiglossum sp,as a result,its pollination effect was better than that of Lasiglossum sp.The foraging activities of Bombus atripes peaked between 7:00 to 7:30,after that,the number of visitors decreased gradually.The foraging activities’peak of Lasiglossum sp was later than that of Bombus atripes.
