Laboratory trials were carried out to investigate the development of three entomophagous parasitoid wasps in preimaginal stages of in monoinfections and mixed infections. Laboratory-raised postfeeding third-stage larvae were exposed to . After pupation, 50 of these fly puparia were brought in contact with pupal parasitoid and 50 with , and the remaining 50 puparia were left as monoinfection. In three further trials, each set of 50 freshly pupated host puparia from the same source was exposed to and , as monoinfections and mixed infections, respectively. The uninfected control group consisted of 50 larvae that were kept separately under the same conditions. The percentages of successfully developed and in monoinfections were 56 and 86%, respectively, and progeny of hatched from 88% of the exposed host puparia. In mixed infections, dominated over and with rates of successfully infected hosts of 50 and 94%, respectively. The number of progeny in these groups ranged from 4 to 49 and 5 to 43, respectively. did not develop in the simultaneous infection with . Not a single eclosed in the six experimental groups, while in the uninfected control group, 46 (92%) adult flies eclosed 11 to 14 days after the start of pupation. Since the three parasitoids emerge from flesh fly pupae, these insects can become important in criminal forensic investigations when corpses are in an advanced stage of decay. More data on their preimaginal development at different temperatures are necessary.
进行了实验室试验，以研究三种食虫寄生蜂在单感染和混合感染情况下在丽蝇预成虫阶段的发育情况。将实验室饲养的取食后第三阶段幼虫暴露于……。化蛹后，将其中50个蝇蛹与寄生蜂蛹接触，50个与……接触，其余50个蝇蛹作为单感染留存。在另外三项试验中，每组50个来自同一来源的新化蛹宿主蝇蛹分别作为单感染和混合感染暴露于……和……。未感染对照组由50个在相同条件下单独饲养的幼虫组成。在单感染中成功发育的……和……的百分比分别为56%和86%，从88%的暴露宿主蝇蛹中孵化出……的后代。在混合感染中，……在……之上占主导地位，成功感染宿主的比例分别为50%和94%。这些组中……后代的数量分别为4至49个和5至43个。……在与……同时感染时未发育。在六个实验组中没有一只……羽化，而在未感染对照组中，46只（92%）成年蝇在化蛹开始后11至14天羽化。由于这三种寄生蜂从肉蝇蛹中羽化，当尸体处于腐烂后期时，这些昆虫在刑事法医调查中可能会变得很重要。需要更多关于它们在不同温度下预成虫发育的数据。
