Abstract
The effects of the eriophyid miteAceria ficus Cotte, the tetranychid miteTetranychus arabicus Attiah and castor-oil pollen on the development and fecundity of the phytoseiid predatorPhytoseius plumifer (C. & F.) were studied. The feeding capacity of all developmental stages ofP. plumifer onA. ficus was also considered.
A. ficus was noted to be the more preferable prey to the predator rather thanT. arabicus. Pollen promoted a marked suppression in the predator's reproduction.
Résumé
Étude des effets de l'eriophyideAceria ficus Cotte, du tetranyqueTetranychus arabicus Attiah, et du pollen de ricin sur le développement et la fécondité du phytoséiide prédateur,Phytoseius plumifer (C & F). On a considéré également la consommation deA. ficus par les différents stades de développement deP. plumifer. Il a été constaté queA. ficus est la proie préférée par rapport àT. arabicus. Le pollen détermine une suppression nette de la reproduction du prédateur.
