| Abstract | ||||
| The accessory gland has a simple structure composed of a single layer of a cells surrounding a lumen that is in turn surrounded by a muscle sheath. It synthesizes a proteins, carbohydrates and lipids which are transferred at the time of mating between male to the mating female. In this study we have determined the number of cells, cell size and gland size in male Drosophila melanogaster, unmated male flies of 2-3 day old were used the exposed to three temperatures, cold(15°c), middle (22°c) and high(29°c) temperature. The results showed, cell size in cold temperature was smaller than middle and high temperature and between three temperatures results of ANOVA and correlation coefficient were significant, p value< 0.01 (cold>middle > high). Results of cell number in cold, middle and high temperature by ANOVA variation and correlation coefficient was significant, the mean value of cell number in high temperature more than low and middle temperature respectively (High> cold> middle). Regarding, gland size, the mean value also, in high temperature condition bigger than middle temperature. The results of ANOVA variation and correlation coefficient were significant. [Our main aim is to show the effect of temperature on the reproductive system, especially on the male accessory gland in Drosophila including, structure of gland of cell size and cell number, that changed when flies were exposed to different temperature]. | ||||
