| 摘 要： | 结果表明,小菜蛾(Plutella xylostella L．)幼虫被菜蛾盘绒茧蜂(Cotesia plutellae(Kurdjumov))寄生后,不能正常化蛹,寄主的脂肪体细胞变态受到明显的抑制．在多分DNA病毒(Polydnavirus,PDV)、畸形细胞等寄生因子存在状态下,经蛋白质双向电泳分析表明,不同寄生状态的小菜蛾脂肪体蛋白组分存在明显差异,与正常发育的寄主脂肪体完全不同．说明菜蛾盘绒茧蜂PDV、畸形细胞以不同的调控方式影响寄主脂肪体的蛋白合成和积累,以满足寄主体内幼蜂发育时营养的需求． |
| 关 键 词： | 菜蛾盘绒茧蜂 小菜蛾 寄生 脂肪体 蛋白质 变态 |

| Abstract: | The results of study showed, when parasitized by the Cotesia plutellae (Kurdjumov) , not only the host larvae of Plutella xylostella L. were unable to pupate, but also their fat body metaporphism was physiologically inhibited. The results of two-dimensional protein electrophoresis showed that protein compositions were different under different effects of parasition factors, such as polydnavirus ( PDV) , teratocytes and so on. Obviously, the PDV and teratocytes played different roles in inhibiting fat body protein accumulation in order to provide nourishment for developing parasitoid larva. |
| Keywords: | C plutellae (kurdjumov) P xylostella L parasitization fat body protein metamorphism |
