Life table parameters of the predatory mite, Blattisocius mali Oudemans (Mesostigmata: Blattisociidae), fed on eggs and larvae of the stored product mite, Tyrophagus putrescentiae (Schrank)

Abstract Background The predatory mite, Blattisocius mali Oudemans (Mesostigmata: Blattisociidae), feeds on various species of storage mites such as Tyrophagous putresentiae (Schrank). In this study, life table parameters and consumption rates B. were determined when fed the eggs larvae T. putrescentiae prey under laboratory conditions. Results Based age-stage two-sex analysis, total pre-ovipositional period (TPOP) predator was considerably lower by feeding host than that eggs. Also, mean fecundity (eggs/female) 2.60-fold higher its Moreover, intrinsic rate increase ( r ), most important parameter 0.272 0.357 day −1 , respectively, mite food.
