摘 要:系统地研究了长木蜂 Xylocopa attenuata Per.的生物学习性和生态关系,1987年首次成功地将这种寡居性木蜂从异地引入草场定居繁殖,迅速扩大了种群。1990年种籽单产比1986年提高3.16倍,引蜂4年中,平均每年比引蜂前单产提高172.4%。取得了显著的生物效益。The relationship between the biological habits and ecology of the long wood bee (Xylocopa attenuata Per.) had been systematically studied.For the first time the bees that live alone were successfully moved to the grass groud from far place in 1987,and then they live together and breed,the group increased rapidly. The yield of herbage seed in 1990 increased 3.16 times as many as in 1986.In 4 years,obviously biologi- cal benefits have been got,the yield has increased 172.4 percent year by year.
