Calyptratae--breeding place
摘 要：
: This paper reports the results of a general survey on the breeding places of common flies in Ya-an Prefecture of Sichuan Province from 1982 to 1984. In the 47 types of breeding place inspected, more than 60 species of Calyptratae and a few undetermined dipterous species were found. Among them the breeding places of 25 species and the prepupae of 3 species living under snow were reported for the first time and the breeding places of other 3 species are new records in China. Only the following 8 species are of epidemiological importance: Chrysomya megacephala, Musca domesiica vicini, Lucilia sericata, Aldrichina grahami, Boett-cherisca peregrina, Heliophagella melanura, Hemipyrellia liqurriens and Parasarcophaga albi-ceps. The breeding places of all these flies can be classified into the following groups: 1. human faeces, 2. animal excrement, 3. decomposing animal matter, 4. decaying vegetable matter, and 5. garbage. They were extensively distributed in the eusynanthropic as well as the semi-synanthropic and asynanthropic zones In human faeces, especially in the latrine and on the ground, Aldrichina grahami, Boencherisca peregrina, Chrysomya megacephala and Heliophagella melanura bred in large numbers. In animal excrement, Musca domestica vicini, Stomoxys calcitrans, Ophyra chalcogaster, Orthellia gavisa and Musca hervei bred profusely. In decomposing animal maters, Galliphoridae and Sarcophagidae such as Lucilia sericata, Aldrichina grahami, Hemipyrellia ligurriens and Parasarcophaga similis were the most common flies found. In decaying vegetable matter, especially bean paste, fodder and weed, Musca domestica vicini, Stomoxys calcitrant and Fannia spp. bred very commonly. The number of fly species breeding in garbage was fairly small; they belongad to Muscidae, Calliphoridae and Sarcophagidae. The overwintering habits of several important species of the flies have been observed. Based upon the above observations, principal methods of fly control are proposed.
