influence of temperature and feedings on development, adult longevity and larviposition of parasarcophaga Hirtipes Wiedemann [diptera: sarcophagidae]

ABSTRACT

In this study, a number of sarcophagid flies was collected from the area of Dokki, Giza and kept in laboratory under normal weather conditions. Adult development, longevity and reproduction of Parasarcophaga hirtipes were studied in relation to variations of temperature and relative humidity during the period from January to May 2002. The mean longevity of adults of both sexes decreased with the increase of temperature and the decrease of relative humidity. The mean larval duration periods were also significantly decreased with the increased temperature, but the mean pupae duration for both sexes did not change significantly during the experiment. The total development time from larvae to adults of both sexes decreased with the increase of temperature. The mean longevity of adults female and male was affected by the presence of both sexes together every day rather than their presence together for only three-day period to allow for one mating to occur. The effects of meat, liver and fish as food constituents on the developmental period, longevity and larviposition of the fly were investigated under a variation of relative humidity and temperature. The mean longevity of adult of both sexes was increased on feeding on meat. The change was not affected when fed on liver and fish. The mean development period of larvae and pupae and the total development period of both sexes did not significantly increase with liver feeding
