Abstract

This work was conducted to determine the effect of three astigmatid stored product mites (immature stages) Tyrophagus putrescentiae, Rhizoglyphus echinopus (Acaridae) and Lepidoglyphus destructor (Glycyphagidae) as food sources on the biology of the two predatory mites, Androlaelaps aegypticus (Laelapidae)and Proctolaelaps gizanensis(Ascidae). Theincubation period,life cycle, longevity and life span of both females and males and the female fecundity (number of laid eggs) of the two mite individuals weresignificantly differed according to the different experiment conditions. The developmental period of both A. aegypticus and P. gizanensis was faster for the male members than females and the immature stages of L. destructor decreased these periods, than other introduced prey. Also, the duration periods were increased at 20ºC than 25 and 30ºC. The number of deposited eggs by females of the two tested predatory mites increased when the adult females fed on the immature stages of T. putrescentiae than other preys, and 30ºC increased this number than other temperature.
