摘要
凹唇壁蜂雌蜂一天能采访近４０００朵花，营造３．５个花粉团巢室，每个花粉团需采集访花量在１１００朵左右。与无蜂授粉比较经壁蜂授粉后可提高青花菜种子产量４～５倍。由此认为壁蜂可以替代蜜蜂在小面积网棚内作为授粉工具，应用于十字花科作物亲本的繁殖。
This is the initial report on Osima excavata Alfken as a pollinator of crucifer crops. The result of the test demonstrated that one Osima excavata Alfken could visit about 4,000 flowers and set up 3.5 pollen pellet cells per day. Osima excavata Alfken as a pollinator could increase the production of broccoli seeds by 4 to 5 times
