“…Parasitoids play a main function in terrestrial food webs (Khan et al 2012) and the study of these webs can provide an essential foundation to improve the effectiveness and comprehension of the decrease of herbivore populations by their natural enemies. For this reason, tri-trophic associations (plant-aphid-parasitoid) have benefited from many studies in several countries (Kavallieratos et al 2004;Khan et al 2012;Rakhshani et al 2012). The fauna of parasitoids in Algeria has attracted great attention in recent years.…”

A study on the fauna of aphids' parasitoids was carried out in the oasis ecosystems of the Ziban in the region of Biskra, Algeria. Eighteen primary parasitoids species belong to 2 subfamilies; Aphidiinae (Hymenoptera: Ichneumonoidea, Braconidae), represented by 17 species and 6 genera (Aphidius, Diaeretiella, Ephedrus, Lysiphlebus, Praon, and Binodoxys) and the subfamily Aphelininae (Hymenoptera: Chalcidoidea, Aphelinidae), represented by only one species of the genus Aphelinus was listed. The parasitoid species were collected and identified in association with 22 species of aphids infesting 29 host plant species belonging to 13 botanical families. A number of 83 tri-trophic plant-aphid-parasitoid associations were presented. The two parasitoid species, Aphidius matricariae (Hal.) and Lysiphlebus testaceipes (Cress.), were the most abundant species. The present study dealt only with primary parasitoids, while hyperparasitoids will be presented in another publication.

Hymenopteran Parasitoids of Aphid Pests within Australian Grain Production Landscapes

In grain crops, aphids are important pests, but they can be suppressed by hymenopteran parasitoids. A challenge in incorporating parasitoids into Integrated Pest Management (IPM) programs, however, is that parasitoid numbers can be low during periods within the season when aphids are most damaging. Understanding the population dynamics of key aphid species and their parasitoids is central to ameliorating this problem. To examine the composition and seasonal trends of both aphid and parasitoid populations in south-eastern Australia, samples were taken throughout the winter growing seasons of 2017 and 2018 in 28 fields of wheat and canola. Myzus persicae (Sulzer) was the most abundant aphid species, particularly within canola crops. Across all fields, aphid populations remained relatively low during the early stages of crop growth and increased as the season progressed. Seasonal patterns were consistent across sites, due to climate, crop growth stage, and interactions between these factors. For canola, field edges did not appear to act as reservoirs for either aphids or parasitoids, as there was little overlap in the community composition of either, but for wheat there was much similarity. This is likely due to the presence of similar host plants within field edges and the neighbouring crop, enabling the same aphid species to persist within both areas. Diaeretiella rapae (M’Intosh) was the most common parasitoid across our study, particularly in canola, yet was present only in low abundance at field edges. The most common parasitoid in wheat fields was Aphidius matricariae (Haliday), with field edges likely acting as a reservoir for this species. Secondary parasitoid numbers were consistently low across our study. Differences in parasitoid species composition are discussed in relation to crop type, inter-field variation, and aphid host. The results highlight potential focal management areas and parasitoids that could help control aphid pests within grain crops.

The family Aphididae (Hemiptera) represents one of the most diverse groups of sap-sucking insect pests referred to as aphids or plant-lice, with 366 species reported in Pakistan, associated with wide array of agricultural and horticultural crops, including fruit and forest trees, weeds, grasses, shrubs, and vines. This work aims to provide an updated checklist of aphids and their associated host plants documented across various regions of Pakistan. The checklist consolidates information from various published literature sources, including annotated checklists, regional distribution data, and host plant records from Pakistan. In this study, we present an annotated checklist of 366 aphid species, belonging to 134 genera and 11 subfamilies, associated with a total of 359 host plant species stretched over 84 families in Pakistan.
