对绒茧蜂的生长发育进行了研究。通过计算卵和幼虫的体积，研究了十字粉蝶（Pieris raiscrucivoraBoisduval）卵和幼虫在寄主幼虫体内的分布。当A.小球蚴产卵后体积增大90倍，孵化出幼虫。幼虫呈指数生长，寄生蜂的生长速度取决于寄主的阶段。寄生在1龄寄主上的寄生蜂比寄生在2 ~ 4龄寄主上的寄生蜂生长缓慢。蛹寄主阶段阻止了拟寄生蜂的发育。当幼虫超过5.0×108μ3的阈值大小时，它们进入2龄。在达到最大体积3.3×109μ3后几天，它们蜕皮并离开宿主。
The growth and development ofApanteles glomeratusL. eggs and larvae in the host larva (Pieris rapae crucivoraBoisduval) was investigated by calculating their volume. WhenA. glomeratuseggs increase 90 fold in volume after being laid, larvae hatch from them. The larvae grow exponentially and the growth rate of the parasitoid is dependent on the host stage. Being laid in the 1st instar host, the parasitoids grow more slowly than those laid in 2nd–4th instar host. A pupal host stage prevents the parasitoids’ development. When larvae exceed the threshold size of 5.0×108μ3, they enter the 2nd instar. A few days after they attain the maximum size of 3.3×109μ3, they moult and egress from the host body.
