Abstract

The predatory mites,Amblyseius gossypi Elbadry andPhytoseius plumifer (Canestrini & Fanzago) successfully went through three generations on a diet of castor-oil pollen and were able to return to their natural prey,Tetranychus arabicus Attiah, apparently unaffected in a way except for a reduction in the predatory efficiency of adultA. gossypi.

Résumé

Les acariens prédateurs,Amblyseius gossypi,Elbadry etPhytoseius plumifer (Canestrini & Fanzogo) élevés pendant trois générations successives avec du pollen de ricin se sont révélés capables de retourner à leur proie naturelle,Tetranychus arabicus Attiah sans être apparemment affectés. Toutefois on a enregistré une diminution de l'activité prédatrice des adultes deA. gossypi.
