Integrative taxonomy of root aphid parasitoids from the genus Paralipsis (Hymenoptera, Braconidae, Aphidiinae) with description of new species
Species from the genus Paralipsis are obligatory endoparasitoids of root aphids in the Palaearctic. It is known that these species are broadly distributed, parasitizing various aphid hosts and showing great biological and ecological diversity. On the other hand, this group of endoparasitoids is understudied and was thought to be represented by a single species in Europe, viz., Paralipsisenervis (Nees). However, recent description of two new species indicated the possibility of cryptic speciation and recognition of additional Paralipsis species in Europe. In this research, Paralipsis specimens collected during the last 60 years from eight European countries, as well as one sample from Morocc…
Species composition and richness of aphid parasitoid wasps in cotton fields in northern China
AbstractThe cotton aphid, Aphis gossypii (Hemiptera: Aphididae), is a serious pest of cotton across the globe, particularly in the cotton agroecosystems of northern China. Parasitic wasps are deemed to be important natural enemies of A. gossypii, but limited information exists about their species composition, richness and seasonal dynamics in northern China. In this study, we combine sampling over a broad geographical area with intensive field trials over the course of three cropping seasons to describe parasitoid-hyperparasitoid communities in cotton crops. We delineate a speciose complex of primary parasitoids and hyperparasitoids associated with A. gossypii. Over 90% of the primary paras…
<strong>Contributions to the Opiinae (Hymenoptera: Braconidae) of Eastern Iran with updated checklist of Iranian species</strong>
The present work collects the checklist of species of Opiinae (Hymenoptera: Braconidae) from Iran and presents new information about the specimens captured in the Sistan and Baluchestan province during 2009–2011. A total of 68 species belonging to eight genera have been listed, of which nine species including Opius ( Hypocynodus ) arundinis Fischer, 1964a; Opius ( Hypocynodus ) bouceki (Fischer, 1958b); Opius ( Opius ) caricivorae Fischer, 1964b; Opius ( Opius ) exilis Haliday, 1837; Opius ( Opiothorax ) opacus Fischer, 1968; Opius ( Allophlebus ) tabificus Papp, 1979; Phaedrotoma biroica (Fischer et Beyarslan 2005a); Phaedrotoma mirabunda (Papp, 1982) and Xynobius rudis (Wesmaelm, 1835) ar…
