Fine structure of the external sheaths of the ovipositor of Aphidius ervi (Hymenoptera: Braconidae) [PDF]
European Journal of Entomology, 2018 The function and structure of the ovipositor in Hymenoptera have been studied intensively, although there is a lack of information on the external sheaths.

A Parasitoid of Aphids Manipulates Host Mummification Site, With Effects on Survival but Not Hyperparasitism [PDF]
Ecology and Evolution, Volume 16, Issue 2, February 2026.Parasitoid wasps can manipulate host behavior to enhance their own survival. Here we find that a parasitoid of aphids, Aphelinus chaonia, induces aphids to move to the leaf axil or leave the plant prior to pupation. This seems to have no effect on hyperparasitism, but mummy location may nevertheless impact parasitoid survival.

The role of Aphidius ervi venom in regulating host nutritional suitability
, 2023 Parasitoid wasps have evolved complex strategies to exploit and regulate the physiology of their hosts and enhance their suitability for the development of their progeny, which are modulated by host regulation factors both of maternal (venom) and embryonic (teratocytes) origin.

Absorption of sugars and amino acids by the epidermis of Aphidius ervi larvae
Journal of Insect Physiology, 2003 Aphidius ervi Haliday (Hymenoptera, Braconidae) is an endophagous parasitoid of several aphid species of economic importance, widely used in biological control. The definition of a suitable artificial diet for in vitro mass production of this parasitoid is still an unresolved issue that, to be properly addressed, requires a deeper understanding both of

Primary parasitoid and hyperparasitoid guilds (hymenoptera) of grain aphid (Sitobion avenae F.) in northern Poland [PDF]
Archives of Biological Sciences, 2015 The aim of this study was to determine and compare the guilds of parasitic Hymenoptera associated with the grain aphid on rye and winter wheat in northern Poland. Of the seven species of primary parasitoids (Braconidae: Aphidiinae, Aphelinidae),

Plant Protection Science, 1999 From the obtained results we can note that the parasitoids in our experiments in 1 997 and 1998 had considerable influence on decline of aphids population density, at which the percent of parasitization in milk maturity stage of wheat was from 2.7 to 35%.

PLoS ONE, 2021 Due to their ability to parasitize various insect species, generalist parasitoids are widely used as biological control agents. They can be mass-reared and released in agroecosystems to control several pest species in various crops.

Plant Protection Science, 2003 During 1997-1999, occurrence of hymenopteran parasitoids of cereal aphids was observed in different localities in Slovakia. Altogether, seven species of aphid parasitoids were recorded.

European Journal of Entomology, 2004 Precocious activity of parasitoids is a key factor for cereal aphid control. We investigated the oviposition, flight and walking capacities at low temperature of four aphid parasitoids (Aphidius rhopalosiphi, A. ervi, Praon volucre, P.
