Abstract

This information on the Russian wheat aphid Diuraphis noxia (Hemiptera, Sternorrhyncha, Aphididae) in those regions of Algeria where
cereals are grown is based on a nineteen year study. This revealed that this aphid is widely distributed in the high plateaus and interior plains
with semi-arid climates. The mummies of this aphid found among its colonies were collected and 4 parasitoids (Hymenoptera, Braconidae,
Aphidiinae) where identified. These were Diaeretiella rapae (M’Intosh), Aphidius matricariae (Haliday), Aphidius rhopalosiphi (Destefani) and
Lysiphlebus testaceipes (Cresson), with D. rapae the most abundant. Moreover, this study also indicates that the cyclical appearance of this
aphid is determined by the intensity of precipitation during winter and spring.
