P. pilosa oviposits in the same day as the fig wasp pollinators, and they can oviposit on the sycouia for two days. Philoirwesis sp. oviposits much later, 6 to 13 days later than the pollinators. The ovaries inside the post-floral phase male syconium of F.

短尾佩妃延腹小蜂的产卵时间与传粉榕小蜂接近，几乎与传粉榕小蜂同时到达隐头果产卵，该时期隐头果可供其产卵2天；而长尾佩妃延腹小蜂的产卵时间较晚，在传粉榕小蜂产卵后的第6天开始到果外产卵，并可持续产卵约一周时间。

Pingbianensis flowers were ants (Aphaenogaster smythiesii Forel,Formicidea), springtail (Hypogastrura sp., Hypogastruridae, Collembola) and one species of beetles (Anomala corpulenta Motsch, Rutelidae). These pollinators generally have restricted movement capacities and hence promote geitonogamy or mating between individuals in close proximity within populations. The results of out crossing index pollination experiments in our study suggest that T. pingbianensis has an animal-pollinated, mixed selfing and outcrossing breeding systems.

通过对屏边开口箭的开花物候、传粉生物学、交配系统的研究以及对近交衰退的检测，结果显示：屏边开口箭单花花期约15天左右，柱头、花粉活力持续时间较长；传粉昆虫多为蚂蚁、跳虫，偶有小甲虫拜访，缺乏长距离传粉昆虫；杂交指数以及套袋试验的结果表明屏边开口箭为高度自交亲和的混交模式植物，且在幼苗早期并没有表现出明显的近交衰退现象。

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。
