【Abstract】 Objective To  study  effect  of  animal  dung  on  the  growing  development of  Musca domestica. Methods M.domestica larvae were reared with animal dung, development period of M.domestica larvae, pupae weight and emergence rate were recorded. Results The weight of M.domestica pupae rearing with chicken dung was the heaviest, about 0.032 g, and the emergence rate and the larva development time were 70% and 7.4 days, respectively. There was no significant difference for pupae weight and larva development time between chicken dung and other dung, but significant difference in the emergence rate (P＝0.022). The larva development time prolonged with the increase of rearing density of M.domestica larvae and height of animal dung. There were different among pupae periods, and the pupal weights decreased with the increase of the time of pupation under the condition of different larvae densities and animal dung height. There was no significant difference in the pupal weights reared with different animal dung at different larvae densities, but the emergence rate of housefly adult was affected. The same as pupae weight, the emergence rate decreased with the increase of the animal dung height. Conclusion The optimization conditions of M.domestica larvae was reared with chicken dung at 30 ℃ and 4-6 cm height.
