Abstract
A laboratory work was conducted to investigate some biological aspects of the predatory mite Holostaspella solimani Alifi, Hassan and Nawar (Macrochelidae: Gamasida). Eight different diets were used. H. soli-man! did not develop beyond the deutonymphal stage when served with the acarid mites, Rhizoglyphus robini or Tyrophagus putrescentiae. Female life cycle ranged between 7.7 and 11.1 days and slightly shorter for the male (7.1 and 10.6 days). The free living nematode Rhizoglyphus scanica and the soil fungi Aspergillus niger were the most suitable diet. Female fecundity averaged 56.7 and 22.0 eggs with daily rate of 3.5 and 0.7 when fed on Rhizoglyphus scanica and Aspergillus niger. respectively. Food consumption increased as stages developed regardless of food type. The highest multiplication rates were 77.71 and 85.57 at 25°C when fed on Ababa's stance alone and mixture of diets, respectively. Female life span averaged 10.3, 7.7 and 4.8 days at 20, 25 and 30°C. Fecundity and nvinnstinn wore hinhar at PAor: than at on nr n nor.
