Abstract: The present paper is an account of the results of a general survey of breeding placesof the common flies in Shanghai District during the years 1954--1955. In this work, morethan 50 spp. of flies are discovered, of which 15 species are more common. Among the15 more common--species, 7 are the most important from the hygienic point of view. Theyare Chrysomyia megacephala, Musca domestica vicina, Lucilia sericata, Sarcophaga spp..Musca sorbens, and Muscina stabulans. Most of them not only are closely related to man,but also have been proved as disease vectors as Well as myiasis producers. Breeding places of flies are classified into 5 types, viz. (1) human feces, (2) animalexcrement, (3) decomposing animal matter, (4) decaying vegetable matter and (5) garbage.Different types of material provide the breeding of different species of flies. In human feces, Chrysomyia megacephala and several species of Sarcophaga breed inlarge numbers. In animal excrement especially in the pig feces and cow dung, Muscadomestica vicina breeds profusely. In decomposing animal matters especially the wastematerial from butchery, such as bones, hairs and furs, Lucilia sericata is the most commonfly found. The number of species of flies breeding in decaying vegetable matter is generallyvery small, it consists of only a small number of few species of Sarcophaga, Fannia andMuscina. In the garbage type of bieeding material, the fly species are most complex, besidesMusca domestica vicina, Lucilia sericata, Sarcophaga spp. and many others are also found. The over-wintering habits of several important species of the flies have been observedand briefly reported. Majority of the more important species hibernate in the pupal or thelarval stages and only Muscina stabulans hibernates as adult female. Basing upon the results of studies on the breeding habits, principal methods of flycontrol are discussed and proposed.
