在实验室饲养的H.绿色的交配，寿命，幼虫，繁殖力和死亡率进行了研究，主要是在控制条件下。雌性幼虫在有或没有宿主或树叶的情况下产卵，蛆在没有宿主的情况下可以存活数天。大理石纹圆蚧可成功寄生任何龄期的寄主，但在第5期（最终）寄主上的存活率显著高于在早期龄期上的存活率。寄生虫幼虫侵入后，蛆虫的存活主要受到以下限制：（1）在宿主蜕皮期间，第一阶段蛆虫与蜕皮物一起丢失;（2）宿主蛹中蛆虫过多，导致寄生虫和宿主死亡。然而，随着过寄生程度的增加，前者通过降低宿主蛹中的蛆密度来增加成蝇的产量。
A culture of Archytas marmoratus was maintained on laboratory-reared H. virescens. Mating, longevity, larviposition, fecundity and mortality were studied, principally under controlled conditions. Females larviposited with or without the presence of hosts or foliage, and maggots could survive several days without hosts. Archytas marmoratus could successfully parasitize any host instar, but survival on 5th-stage (ultimate) hosts was significantly greater than that on earlier instars. Survival of maggots, following penetration of the host larva, was largely limited by (1) loss of 1st-stage maggots with the exuviae during host ecdysis and (2) overabundance of maggots in the host pupa resulting in death of both parasite and host. However, with an increasing degree of superparasitism, the former increased production of adult flies by lowering maggot density in the host pupa.
