Effect of Different Levels of Illumination on the Life Cycle of the Face Fly12

Abstract

Face flies were reared under illumination levels of 5, 50, or 500 ft-c, produced by daylight fluorescent lamps, and their life cycles compared. The photoperiod consisted of 16 hr. of light and 8 hr of darkness. After 4 generations there appeared to be no significant differences in the life cycles of the flies reared under these levels of illumination. At 83 [degree]F eggs hatched after about 24 hr., the larvae completed development in 4-5 days, and the pupal stage was completed in 6-7 days.
