| Abstract | ||||
| Aphids are categorized as serious pests, causing different damages to plant species; they have a great number of known natural enemies as predators and parasitoids. Among parasitoids, all members of the Aphidiinae subfamily were considered the most important. Pauesiaspecies are restricted to Lachninae aphid hosts. In Algeria, there is a lack of formations of Pauesia species richness. This study conducted in the forest habitat of Khenchela province dominated by Aleppo pine aims to explore Pauesia diversity in this region. A total of 208 mummified Cinara maghrebica (Mimeur) aphid were collected on Pinus halepensis trees. Among them, 106 Pauesia silana have emerged in association with males of a second species (Pauesia sp) and two hyperparasitoid species Asaphes suspensis(Nees) and Asaphes sp. Pauesia silana Tremblay is reported for the first time in Khenchela province. This natural enemy was found only parasitizing the aphid Cinara maghrebica (Mimeur) feeding on Aleppo pine (Pinus halepensis). Pauesia silana is redescribed and illustrated. | ||||
