Abstract

Four aphid species are known to colonize peach and almond in Tunisia: Hyalopterus pruni species complex, Myzus persicae Sulzer, Brachycaudus amygdalinus Shouteden and Pterochloroides persicae Cholodkovsky. Eggs identification, date of lay and effect of orientation on egg laying were described. Brief information about biology, preferential host, distribution and growth rates are given for each species.
