| 摘 要： | 啊氏啮小蜂(Tetrastichus hagenowii)是美洲大蠊卵的寄生蜂,越新鲜的美洲大蠊卵荚被寄生率越高,不同日龄卵荚寄生率(y)与卵荚日龄(x)的关系符合方程y=-0.6 943x+34.158(R2=0.9205).寄生不同日龄卵荚的啊氏啮小蜂的发育历期(y)随着美洲大蠊卵荚日龄(x)的增加而缩短,符合方程y=-0.4411x+43.404(R2=0.9467).寄生蜂的雌雄性比(y)也随着寄主日龄(x)的增大而降低,符合方程式y=-1.4349x+89.435(R2=0.9331).

| Abstract: | Tetrastichus hagenowii is an egg parasite of cockroaches.It prefers ovipositing in fresh oothecae to old ones.The relationship between the parasitism(y) and the host age(x) can be simulated with the following equation y=-0.6943x+34.158(R~2=(0.9205)).The developmental period(y) and the ratio of female(y) of descendants of T.hagenowii respectively become shorter and lower with the increase of the host egg growth(x),which cound be respectively simulated with the equations y=-0.4411x+43.404(R~2=0.9467),y=-1.4349x+89.435(R~2=0.9331). |
