Seasonal abundance of fly species in the animals farm of Sohag university, Egypt

Abstract

The present study was carried out in the Faculty of Agriculture, Sohag University, Sohag Governorate, Egypt during 2018-2019. The results recorded that the spring season was the most suitable for the activity of flies in different species, followed by summer, then autumn, and then the population decreased during the winter season. The incidence rates of flies were recorded as follows: 47.1, 30.1, 16.1 and 6.7% during spring, summer, autumn and winter respectively. These differences in the numbers of flies during the different seasons are mainly due to climate change, especially temperature. The house fly was the most common species found in Farm throughout the year by 69.7%, while the rest of the species ranged from 4.1 to 10.9% during 2018. The same trend of results was recorded on the same farm in 2019. These results are useful for determining the time of fly control programs in animal farms.
