    ABSTRACT
    Several species of hyperparasitoids belonging to the subfamilies Charipinae (Hymenoptera: Figitidae) and Pteromalinae (Hymenoptera Pteromalidae) have been identified in the region of Mostaganem (north-western Algeria). Among these species, two of them show a regular presence during the years of study, Pachyneuron aphidis (Bouche, 1834) (Pteromalidae), and Phaenoglyphus villosa (Hartig, 1841) (Figitidae). These two species have been proved to be effective in adapting very quickly to the environment.

    ABSTRACT
    Myzus persicae (Sulzer, 1776) (Hemiptera Aphididae) is the most significant aphid pest of peach trees. Chemical control of this species is a quick and simple method to prevent the development of this pest, however, the massive use of these chemicals poses potential health and environmental risks. This study proposes an alternative biological control approach based on the use of parasitoids to reduce aphidian populations. The study, which we undertook over the course of three years, allowed us to observe almost the same species of parasitoid (Hymenoptera Braconidae) on the vegetable crops taken into exam in the study. However, some species were considered to be absent in the region. Others appeared only during the second and last year of study as Aphidius funebris Mackauer, 1961, Trioxys angelicae Haliday, 1833 and Praon exsoletum Nees, 1811. This study showed total dominance of A. matricarae Haliday, 1834 with very high parasitism (values of 61%, 54% and 78% during 2012, 2013 and 2014, respectively) followed by Lysephlebus testaceipes Cresson, 1880.
