Revision of the genus Aphelinus Dalman (Hymenoptera: Chalcidoidea: Aphelinidae) in Norway with descriptions of 3 new species

Abstract

Hymenoptera, Diptera, and Lepidoptera; most species are associated with Hemiptera in the superfamilies Coccoidea, Aleyrodoidea, and Aphidoidea (Yasnosh, 1995). The species of the genus Aphelinus are parasitoids of sap-sucking aphids in Aphidoidea (Hemiptera). Aphids are of quite considerable economic importance, as they damage many horticultural, forest, and fruit plants, and are the cause of leaf distortion and flagging terminals. Infested plants have reduced growth and vigor. With severe infestations, leaf yellowing and twig dieback may occur. Species of Aphelinus have been used in biocontrol against many aphid pests, most successfully Aphelinus mali for the biological control of Eriosoma lanigerum (Hausmann), the apple woolly aphid (Nikolskaya and Yasnosh, 1966; Yasnosh, 2002). The latest works on Aphelinus from Europe were done by Japoshvili and Abrantes (2006) and Japoshvili and Karaca (2009). The aim of this study was to review genus Aphelinus species housed in the Natural History Museum of Oslo University in order to record the fauna of Aphelinus species of Norway. 2. Materials and methods The Aphelinus collection housed in the Natural History Museum of Oslo University was studied. The material was collected during 1953-2008 using all major methodologies for Aphelinidae including direct rearing from the host, sweeping, yellow-pan traps, and Malaise traps. Terminology follows that of Nikolskaya and Yasnosh (1966), Graham (1976), and Yasnosh (1963-2002). The following abbreviations are used in the text: AOL, anterior ocellar line (the shortest distance between the anterior and posterior ocelli); DAO, diameter of anterior ocellus; DPO, diameter of posterior ocelli; EL, maximum eye length; F1, F2, etc., first funicle segment, second funicle segment, etc.; FV, maximum frontovertex width; GL, maximum gonostylus (third valvula) length; GW, gonostylus width; MS, malar space (the shortest distance from the eye to the mouth margin); MSL, malar space (distance from eye margin to clypeus); MT, midtibia length; OOL, ocular-ocellar line (the shortest distance between posterior ocellus and adjacent eye margin); POL, posterior ocellar line (the shortest distance between the posterior ocelli). Specimens were card-mounted and slides were done according to Noyes's (2013) methodology. The collection of Aphelinus spp. is located in the Natural History Museum of Oslo University Norway as all type material of new species. For identification, we used a binocular stereomicroscope "MICROS" model: MS1107/MZ1280/ MC1280. Drawings were done by the first author by hand.

First report of the parasitoid Aphelinus chaonia Walker, 1839 (Hymenoptera: Aphelinidae) in Algeria and its host aphid Takecallis arundicolens Clarke, 1903 in Africa

“…According to Lopes et al ., (2016), A. chaonia is reported in many countries, such as Austria, Azerbaijan, Brazil, Chile, China, Croatia, the Czech Republic, France, Georgia, Germany, Hungary, Lithuania, Montenegro, Netherlands, Norway, Pakistan, Poland, Portugal, Russia, Serbia, Slovakia, Spain, Sweden, Turkey, Ukraine, the United Kingdom, and the United States. Japoshvili & Hansen (2014) mentioned their existence in the Canary Islands, Egypt, Georgia, Madeira, Montenegro and Nepal.…”

“…This study was conducted in three study sites as a part of a survey of the hymenopteran parasitoids of aphids in Algiers between February 2017 and June 2018. Identification of both the aphid and its parasitoid was carried out in the Zoology Laboratory of the Superior National Veterinary School (ENSV), Algiers using the keys of Blackman & Eastop (1994) and Japoshvili & Hansen (2014), respectively. The studied specimens were deposited in the insect collection of the Zoology Laboratory of ENSV, Algiers.…”

Checklist of Aphidiinae (Hymenoptera: Braconidae) and Aphelinus (Hymenoptera: Aphelinidae) species from Belgium with respectively four <br />and three new records

“…For example, 24 Aphidiinae species are recorded in Norway (Westrum et al 2010) and 180 in Germany (Belokoblylskij et al 2003). As for Aphelinus, eight species are recorded from Portugal (Japoshvili & Abrantes 2006) and 11 from Norway (Japoshvili & Hansen 2014;Japoshvili et al 2015). Several Aphidiinae and Aphelinus species listed for Belgium can also be found in countries where the climate may differ considerably, such as Iran (Barahoei et al 2014) and Georgia (Japoshvili & Karaca 2009).…”

“…Aphelinus species were identified by the fourth author using the keys of Nikol'skaya & Yasnosh (1966), Japoshvili & Abrantes (2006), Karaca (2009), andHansen (2014).…”
