Abstract

In this study, a total of 108 Aphidiinae species, belonging to 18 genera, associated with 240 aphid species in 16 countries of the Middle East and North Africa are reviewed. 743 host aphid-parasitoid associations are listed. New material was collected from various regions of Saudi Arabia during 2011–2013. Three species including Aphidius avenae Haliday, 1834, Aphidius platensis Brèthes, 1913 and Praon barbatum Mackauer, 1967 are first recorded for the fauna of this country. Lysiphlebus marismortui Mescheloff & Rosen, 1990 syn. nov. is classified as the junior synonym of Lysiphlebus confusus Tremblay & Eady, 1978. An illustrated up-to-date key to all known species of Aphidiinae that occur in the Middle East and North Africa is provided. The findings are discussed in relation to the overall parasitoid-aphid associations in the target investigated region.

Highlights

  • Members of the subfamily Aphidiinae (Hymenoptera: Braconidae) belong to an important group as natural enemies of aphids (Starý 1970)

  • The rest of the data have been extracted from literature that refers to taxonomy, faunal diversity and biology of Aphidiinae parasitoids in various countries of the Middle East and North African countries

  • A total of 108 Aphidiinae species, belonging to 18 genera, associated with 240 aphid species in 16 countries of the Middle East and North Africa are reviewed. 743 host aphid-parasitoid associations are listed in the target area

Summary

Introduction

Members of the subfamily Aphidiinae (Hymenoptera: Braconidae) belong to an important group as natural enemies of aphids (Starý 1970). Aphidiinae consist of solitary koinobiont parasitoids, among which several species are considered highly efficient biological control agents (Hågvar & Hofsvang 1991; Boivin et al 2012). This subfamily includes about 505 species belonging to 38 genera, around the world (Žikić et al 2017). Aphidiinae are strictly associated to their host aphids, regarding local distribution and/or broader expansions (Starý 1981a). The complexity of biogeographical factors determines the area of distribution of parasitoid species and directly affects the host associations (Hawkins 1994). The host plants have a crucial impact concerning the diversity of the feeding insects, especially on aphids and their parasitoids (Starý 1981a; Žikić et al 2017)
