小蜂科

There were 22 pollinating insect species belonging to 4 orders and 11 families, among which, native bee species Megachile abluta, M. spissula, Xylocopa valga, Andrena parvula and Anthophora melanognatha were the main pollinators. M. abluta, M. spissula and X. valga were of uni-peak type with diurnal foraging activities trom 11:30 to 15:30, while A. parvula and A. melanognatha were of double-peak type with diurnal foraging activities on 9:30-11:30 and 16:30-18:30, indicating a complementary relationship among the pollinators. The main pollinators had significant differences in their tripping frequency and landing time, and their foraging behaviors were correlated with their body sizes.

结果表明：苜蓿访花昆虫共计22种，分别属于4个目，11个科，根据弹花效率初步确定鳞地蜂、黑颚条蜂、净切叶蜂、细切叶蜂和紫木蜂为河西地区主要传粉昆虫；主要传粉昆虫的日活动规律出现单峰型和双峰型2种，净切叶蜂、细切叶蜂和紫木蜂属于前者，只在11：30-15：30出现一个活动高峰，而鳞地蜂与黑颚条蜂则为双峰型，在9：30-11：30和16：30-18：30分别出现访花高峰，不同的传粉昆虫之间存在互补关系；主要传粉昆虫的弹花频率和小花停留时间存在显著差异，且访花行为与野生蜂体型紧密相关。
