Abstract
The present study aims to determine different biological aspects of the commonest soil predaceous mites, Androlaelaps casalis ( Berlese ) and Laelaps  astronomicus Koch 1839 (Laelapidae) which were collected  from untreated onion soil; at Qaha region, Qaluobia Governorate when reared on free living nematodes, Rhabditella muscicola Andrassy and the acarid mite, Tyrophagus putrescentiae (Schrank) at 20, 25 and 30 ˚C and 70 % R.H. The study indicated that there were nonsignificant differences between the incubation period of A. casalis and L. astronomicus when fed on different diets.The female and male life-cycle of the two predacious  mites when feed on free nematodes was significantly longer than those fed on T. putrescentiae. The pre-oviposition and post-oviposition periods of A. casalis and L. astronomicus were nonsignificantly affected by the prey typesat the different temperatures. On the other hand, there were obviously differences when the mites fed during their ovipostion time on the same foods at the same temperatures. The study showed that the longevity of the A. casalis and L. astronomicus differed significantly when the adult female and male fed on the different diets at different tempertures.The current study also indicated that the feeding of the predacious  mites A. casalis and L. astronomicus on nematode increased the number of deposited eggs by the mite female compared with those  fed on the acarid mite.
