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.

Abstract: 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 (3^rd instar 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 3^rd instar mealybugs. The hind tibia length of the offspring wasp was closely related to the body length. The body size of the parasitised 3^rd instar 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.
