The Cheyletid mite, Cheletogenesornatus (C. & F.) (Actinidida: Cheyletidae) was reared at 20
and 25+2°C
and 60-65% R.H. on
eggs and immature stages of Astigmatid mite, Acarus farrie (Oudemans). The predatory mite C. ornatus fed successfully on the tested food . Results indicated that female predator had two nymphal stages, while the
male had one nymphal stage. It was significant differences between the male and
female during  immature stages and life
cycle,; the longest period was 21.28 and 29.77 days for females which fed on
immature stages of A. farrie, the shortest values was observed for males which fed
on egg of A. farrie were
13.9 and 22.08 days, respectively. The longest Oviposition period  observed  was 22.52 days, at 25 °C while, the shortest
period was 20.75 days at 20 °C when the adult female fed on eggs of A. farrie. Fecundity was significantly higher when the adult
female fed on eggs of A.
farrie at 25 °C and decreased to recorded the lowest number
of deposited eggs at 20°C. There was significant different effect of the
temperature on female and males food consumption during longevity,; the highest
number consumed by female and male was recorded at 20 °C, whereas the lowest
number was record at 25 °C.
