摘  要：
为明确寄主虫态对班氏跳小蜂适合度的影响,在实验室条件下[温度(27±1)℃,相对湿度(70±5)%,光周期14L∶10D]测定了寄生于不同发育阶段(3龄若虫和雌成虫)扶桑绵粉蚧的班氏跳小蜂子代性比和个体大小.结果表明:寄生扶桑绵粉蚧雌成虫的班氏跳小蜂的子代雌雄性比、个体体长和后足胫节的长度均明显高于寄生3龄若虫,且个体体长与后足胫节长度之间有显著的相关性.扶桑绵粉蚧3龄若虫个体大小显著影响班氏跳小蜂子代个体大小,而雌成虫的个体大小对该蜂子代大小无显著影响.

摘  要：
To understand the effects of host stage on the fitness of the offspring Aenasius bambawalei Hayat,the sex ratio and body size of their offsprings parasitizing Phenacoccus solenopsis Tinsley of different stages(3rdinstar nymph and adult) were determined under the laboratory conditions of(27 ±1) ℃,RH(70 ±5) % and 14L∶ 10D.Sex ratio,body length and hind tibia length of the offsprings of A.bambawalei parasitizing the P.solenopsis adult females were significantly higher compared to those parasitizing the 3rdinstar mealybugs.The hind tibia length of the offspring wasp was closely related to the body length.The body size of the parasitised 3rdinstar mealybugs affected the size of the offspring wasp of A.bambawalei significantly,while such relationship was not found between the adult female of mealybugs and the offspring wasp.
