| 摘 要： | 比较了以冷冻和活体家蝇蛹以及大、小活体家蝇蛹为寄主时蝇蛹金小蜂的后代产量和性比策略差异,结果表明：冷冻家蝇蛹可以被小蜂利用,但小蜂后代产量显著低于以活体蛹为寄主时;在以大、小蝇蛹为寄主时,后代蜂产量和性比均无显著差异;建群者并未根据寄主大小调整后代性比,这可能是受寄主大小差异范围的影响,该小蜂在不同大小寄主时的性比策略尚需进一步探讨。

| Abstract: | The progeny production and sex ratio strategy of Pachycrepoideus vindemmiae(Rondani)parasitizing on frozen and live house fly pupae,and big and small house fly pupae were studied.The results showed that the wasp can utilize frozen pupae,but the progeny production was significantly lower than that parasitizing live pupae.Sex ratio of the wasp parasitizing on the big and small pupae was similar.The parasitoid wasp donot change the peogeny sex ratio when given small or big hosts.The reason may be the limited d... |
