Cohen, A. Horowitz, D. Nestel, D. Rosen] Sensibilité du parasitoïde, Aphelinus mali (Hym. Aphelinidae) aux pesticides couramment utilisés en verger de pommiers en Israel The effects of one acaricide (cyhexatin), two fungicides (penconazole and sulfur), and six insecticides (azinphos-methyl, chlorpyrifos, imidacloprid, pirimicarb, triazamate and vamidothion) on the adult stage of the parasitoidAphelinus mali (Haldeman), a parasite of the woolly apple aphidEriosoma lanigerum (Hausmann), were investigated under laboratory conditions. Chlorpyrifos (an organophosphorus insecticide-OP) was found to be highly toxic to the adult wasps. Vamidothion (OP) was more toxic to the parasitoid than azinphos-methyl (OP). On the other hand, both chlorpyrifos and azinphos-methyl were found to be harmless to the immature stages of the parasitoid in a test conducted under semi-field conditions. Of the other insecticides, imidacloprid was more toxic to the adult parasitoid than pirimicarb and triazamate. Neither cyhexatin nor penconazole had a considerable toxic effect upon the parasitoid. In contrast, sulfur was found to be moderately toxic to the parasitoid under laboratory conditions, as well as in a field survey in which we followed populations ofE. lanigerum andA. mali parasitization in sulfur-treated plots, and in a plot treated withAmpelomyces quisqualis Ces., a fungus antagonist to powdery mildew. The implications of these results to IPM programs of apple orchards in Israel are discussed Lavoisier Abonnements, 1996 Aphelinus mali nationallicence Eriosoma lanigerum nationallicence pesticides nationallicence IPM nationallicence Cohen H.
