Published: October 2020

To ensure their own immature development as parasites, ichneumonid parasitoid wasps use endogenous viruses that they acquired through ancient events of viral genome integration. Thousands of species from the campoplegine and banchine wasp subfamilies rely, for their survival, on their association with these viruses, hijacked from a yet undetermined viral taxon. Here, we give an update of recent findings on the nature of the viral genes retained from the progenitor viruses and how they are organized in the wasp genome.

The All Taxa Biodiversity Inventory (ATBI) in Great Smoky Mountains National Park (GSMNP) seeks to document every species of living thing in the park. The ATBI is decades in progress, yet some taxa remain virtually untouched by taxonomists. Such "high priority" taxa include the hyper-diverse parasitoid wasp family Ichneumonidae.

Article Synopsis
  • Thousands of endoparasitoid wasp species from the Braconidae and Ichneumonidae families carry domesticated endogenous viruses (DEVs), specifically ichnoviruses (IVs), in their genomes.
  • The study focuses on how large quantities of IV virions are produced in the ovary calyx cells of female wasps, especially during pupal and adult stages, and how these virions aid in the successful development of wasp offspring by infecting host insects.
  • Researchers generated a detailed genome assembly for the Hyposoter didymator wasp and identified 67 HdIV loci, concluding that a specific gene, U16, is crucial for both the amplification of these loci and the formation of vir

A faunistic inventory of ichneumonoid wasps collected from faba bean fields (Vicia faba L.) in Kharga Oasis, New Valley, Egypt is presented. Fourteen species of Braconidae in 11 genera and five subfamilies (Aphidiinae, Braconinae, Euphorinae, Microgastrinae, and Opiinae); and six ichneumonid species in five genera and three subfamilies (Campopleginae, Diplazontinae, and Ichneumoninae) were collected and identified.

Hymenoepimecis is a genus of Darwin wasps in the Polysphincta group of genera (Hymenoptera: Ichneumonidae: Pimplinae) known as ectoparasitoids of a broad spectrum of spiders. The parasitoid induces production of a web known as cocoon web, which provides shelter and support for the wasp pupa. In this study, we describe for the first time the interaction between Hymenoepimecis castilloi Pádua & Sääksjärvi (Hymenoptera: Ichneumonidae) and its host spider Leucauge mariana (Taczanowski) (Araneae: Tetragnathidae) in the Colombian Andes, provide new records of wasp genus distribution, and described the behavioral modifications induced in the spider.

Understanding how biodiversity varies from place to place is a fundamental goal of ecology and an important tool for halting biodiversity loss. Parasitic wasps (Hymenoptera) are a diverse and functionally important animal group, but spatial variation in their diversity is poorly understood. We survey a community of parasitic wasps (Ichneumonidae: Pimplinae) using Malaise traps up a mountain in the Brazilian Atlantic Rainforest, and relate the catch to biotic and abiotic habitat characteristics.
