近年来,蛴螬对一些地区的园林花卉为害严重,造成经济损失较大。钩土蜂可在蛴螬上进行体外寄生,以幼虫取食寄主体液及体躯。此蜂一年一代,以老熟幼虫在土茧内越冬。当雌蜂入土找到寄主后,用螫针注射毒液于寄主的胸部背板处,使其麻痹,再将卵产于胸部背板二三节处。卵以胶质物粘附于寄主体壁上。一头钩土蜂在一头蛴螬上可产卵1—2粒,多的可达10多粒。一般只能发育成一头幼虫,少数也可发育成2—3头,自
In recent years, shaddocks have caused serious damage to garden flowers in some areas, resulting in greater economic losses. Hook bumble bees can be carried out in vitro parasitism, the larvae feeding host fluid and body. This bee is a year old, with mature larvae overwintering in soil cocoon. When the female bees found the host, the needle injection of venom on the host’s chest back venous at paralysis, then the eggs produced in the chest back at twenty-three. Eggs adhere to the host body wall with gummy substances. A hook bumblebee in a slug can spawn 1-2 tablets, more than 10 up to more tablets. Generally only develop into a larvae, a few can develop into 2-3 heads, since
