Abstract:

Apterous green peach aphids, Myzus persicae (Sulzer), collected from potato plots treated with azinphosmethyl, when caged on either treated or nontreated foliage, produced 20-30% more offspring than aphids that were not exposed to the insecticide. The increase in fecundity resulted directly from the action of the insecticide on the reproduction of the aphids rather than indirectly from changes induced by the insecticide in the host potato plants. Suitability of plants to support populations of aphids varied within and between seasons. Applications of azinphosmethyl did not alter ability of the plants to support aphid populations.
