Abstract: This paper reported the develpment zero and effective accumulative temperature of Musca domestica L. and calculated the occurrence generations and the peak of adult density in the whole year according to the data of local temperature. The results showed that the development zero was 8.2℃, and the effective accumulative temperature was 241.25(day-deg-ree). In a year, Musca domestica L can breed 12 generations, and there are two peaks of adult density-June and September. It is conformable with the practical investigation that we have made. This method is of great importance for working out the control strategies.

摘要： 本文报告在自然变温条件下测定的家蝇各虫态及全世代发育起点温度(C)和有效积温常数(K);并利用积温法则,根据当地气温情况,预测了当地家蝇全年发生代数及成蝇密度高峰期。结果表明:家蝇全世代发育起点温度为8.2℃,有效积温K为241.25(日·度),家蝇在济南地区全年发生12代,成蝇密度高峰期在6月及9月,与实际调查结果基本相符。认为利用积温法则预测家蝇发生量,对制定防制策略具有重要意义。
