Abstract

The effect of diet on the biology of the predatory mite Amblyseius denmarki Zaher & El-Borolosy (Acari: Phytoseiidae) was studied in the laboratory. Predatory mites fed on the eriophyid mites eriophyes dioscoridis, E. olivi and Cisaberoptus kenyae had a faster development, higher fecundity and a more female-biased sex ratio than those fed on the other diets tested, namely pollen of the palm Phoenix dactylifera, the scale insect Parlatoria ziziphus and the whitefly Bemisia tabaci.

Key words

Résumé

L’influence du régime alimentaire sur la biologie de l’acarien prédateur Amblyseius denmarki Zaher & El-Borolosy (Acari: Phytoseiidae) a été étudiée au laboratoire. Les acariens prédateurs nourrit avec les acariens eryophyid eriophyes dioscoridis, E. olivi et Cisaberoptus kenyae ont un développement plus rapide, une fécondité plus élevée et un sex ratio en faveur des femelles moins biaisé que ceux nourrit avec les autres régimes alimentaires, àsavoir le pollen du palmier dattier Phoenix dactylifera, la cochenille Parlatoria ziziphus et la mouche blanche Bemisia tabaci.
