| Abstract | ||||
| The mite, Blattisocius mali (Oudemans) (Acari: Ascidae) was reared at 25 ± 1 °C and 75 ± 5 % R.H. on the immatures of the Astigmatid mite, Rhizoglyphus robini Claparede and the free-living nematodes (FLN), Rhabditis sccanica Allgen. The mean incubation period of B. mali was 1.85 and 1.55 days when fed on immature stages of R. robini and 1.84 and 1.54 days when fed on R. sccanica for females and males, respectively. The duration of the life cycle for both sexes of B. mali was significantly affected by the kind of food used and took 8.68 and 7.73 days when fed on R. sccanica of females and males, However this duration lasted longest times for B. mali averaged 9.89 and 8.91days when fed on R. robini, female and male individuals, respectively. Adult longevity of B .mali was influenced by the type of food employed, this period lasted 27.87 and 21.8 days on R. sccanica. This period was 29.46 and 24.22days on R. robini females and males individuals, respectively. The current study indicated that the free living nematode proved to be the most favorable diets as it gave the highest fecundity rate (86.5 eggs). On the contrary, the least number of eggs were deposited by B. mali during feeding on immature of R. robini (37.7eggs). During the development time of life span B.mali, the total number of the tested consumed prey was significantly differed. It was 138.7and 90.4 preys when the B. mali males and females fed on R. robini, respectively. | ||||
