| Abstract | ||||
| This study is conducted to throw some lights on the effect of some food stuffs on the main biological aspects of the acarid mite, T. putrescentiae at 25 ºC and 75 % R.H..The study indicated that there was a slightly significant difference between the incubation period of T. putrescentiae female and food types. The females reached maturity (life cycle) in 11.1, 12.5, 13.3 and 14.0 days when fed on wheat flour, milk powder, fish powder and granular chicken feed, respectively. Female longevity was the longest on wheat flour (39.0 days) while it was recorded the shortest time on fish powder (25.1 days).The female needed 34.6, 30.4, 22.8 and 21.0 days for egg deposition, respectively. The highest number of deposited eggs was recorded on wheat flour (39.0 eggs), while the lowest was on fish powder (27.8 eggs) as feeding source. However, the male life cycle duration was significantly affected by the food type, as it averaged 9.8, 10.3, 12.4 and 13.2 days on the aforementioned diets, respectively. Male adulthood was the longest on wheat flour (28.7 days) while decreased to 17.0 days on fish powder. The male life span lasted 38.5, 34.2, 31.2 and 30.2 days, when fed on the above mentioned diets, respectively. | ||||
