The development was not completed when the phytoseiid mite fed on pollen grains of Ricinus communis (L.) and Phoenix dactylifera (L.) as an alternative food substance. The duration of the immature stages and adult stage were determined. The adult female daily consumed 17 and 102 individuals of T. urticae and E. dioscoridis respectively. The daily reproduction was 1.3 eggs per day when fed on eriophyid mites, while the number of eggs deposited increased (1.9 eggs/female/day) when fed on tetranychid mites. ER -
