Musca vicina and M. domestica were induced to feed on stools containing eggs of hook worm and Ascaris lumbricoides and on infective larvae of the parasites. The development periods of the regurgitated eggs were observed while attempts were made to recover the ingested larvae through regurgitation. Results showed no difference between the developmental periods of eggs of hookworm and A. lumbricoides recovered from the houseflies up to 2 hours post ingestion and eggs of the same parasites which were not fed to the houseflies. In the case of infective larvae of hookworm, almost all experimental flies regurgitated infective larvae up to 8 hours post ingestion; the number of flies with this ability dropped very drastically as from the 9th hour. In addition, the number of larvae recovered decreased steadily as from the 5th hour post ingestion until it almost seized by the 9th hour. Such decreases in number of houseflies from which larvae were recovered and in the number of larvae recovered were not experienced with A. lumbricoides.
诱导厩螫蝇和家蝇取食含有钩虫和蛔虫卵的粪便以及这些寄生虫的感染性幼虫。观察反刍出的卵的发育时期，同时尝试通过反刍回收摄入的幼虫。结果表明，在摄入后长达2小时从家蝇体内回收的钩虫和蛔虫卵的发育时期与未喂给家蝇的相同寄生虫的卵之间没有差异。就钩虫的感染性幼虫而言，几乎所有实验蝇在摄入后8小时内都会反刍出感染性幼虫；从第9小时起，具有这种能力的蝇的数量急剧下降。此外，从摄入后第5小时起，回收的幼虫数量稳步减少，到第9小时几乎停止。蛔虫没有出现回收幼虫的家蝇数量和回收幼虫数量的这种减少情况。
