This paper deals with the investigation on piggery pollution and the trials on the pollution control through feeding insects with pig dung. The results show that there are more than 10 species of insects which can feed on pig dung, and most of them belong to Calliphoidae and Stratiomyiidae of Diptera, indicating that pig dung is a good kind of feed for saprophytic insects.According to the ability of digesting dung, three dominant species are selected, and their life history, generation duration, feeding habit and behaviors are studied. 70% of the pig dung can be digested by raising a large amount of insects, and these raised insects can be used as a protein resource for poultry and livestock husbandry, and aquatic product industry.
