New records for the association between eulophid parasitoids (Hymenoptera: Chalcidoidea: Eulophidae) and gall wasps (Hymenoptera: Cynipoidea: Cynipidae and Diplolepididae)

open access: yesTurkish Journal of Forestry
To expand knowledge on gall communities, we identified 10 species from 6 genera within the family Eulophidae (Hymenoptera: Chalcidoidea) found in oak and rose galls (formed by Cynipidae and Diplolepididae) collected in northeastern Anatolia. The eulophid

Oviposition at low temperatures - late season negatively affects the leaf beetle Galeruca tanaceti (Coleoptera: Galerucinae) but not its specialised egg parasitoid Oomyzus galerucivorus (Hymenoptera: Eulophidae)

open access: yesEuropean Journal of Entomology, 2006
Insects experience important selection pressures from their parasitoids, which affect both their population dynamics and their evolutionary responses. The interaction between the egg parasitoid Oomyzus galerucivorus Graham (Hymenoptera: Eulophidae) and ...

Sex ratio distortion in the Nesolynx thymus (Hymenoptera: Eulophidae), an ecto-pupal parasitoid of uzifly, Exorista sorbillans (Diptera: Tachinidae)

open access: yesEuropean Journal of Entomology, 2014
The reproductive alterations induced by maternally inherited α-proteo-bacteria Wolbachia to their hosts is a well-documented phenomenon. In Nesolynx thymus, a gregarious hymenopterous ecto-pupal parasitoid of the uzifly, Exorista sorbillans, diagnostic ...

Parasitoid complex and parasitism rates of the horse chestnut leafminer, Cameraria ohridella (Lepidoptera: Gracillariidae) in the Czech Republic, Slovakia and Slovenia

open access: yesEuropean Journal of Entomology, 2006
The horse chestnut leaf miner, Cameraria ohridella Deschka & Dimić, is a species of unknown origin that recently invaded most of Europe, causing serious damage to horse chestnut trees, Aesculus hippocastanum. Parasitism was studied over a period of three

Selective leaf surface defenses: trichomes trap herbivorous leafminers but spare parasitoid wasps

open access: yesPest Management Science, EarlyView.
Hooked trichomes on kidney bean leaves selectively entrap leafminer flies but rarely affect parasitoid wasps. This morphological barrier enables pest suppression with minimal impact on beneficial insects, offering insights for breeding pest‐resistant cultivars compatible with biological control. Abstract BACKGROUND Leafminers [e.g., Liriomyza trifolii (

Feasibility of Using Cryostored Colorado Potato Beetle (Coleoptera: Chrysomelidae) Eggs for Rearing \u3ci\u3eEdovum Puttleri\u3c/i\u3e (Hymenoptera: Eulophidae) [PDF]

open access: yes, 2018
Cryostored eggs of Colorado potato beetle, Leptinotarsa decemlineata (Say) eggs were suitable hosts for Edovum puttleri. Parasitism rates were low, however this study was first to show that rearing the parasite on eggs stored at ultra low temperatures ...

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Leptocybe invasa Fisher & La Salle, 2004 and Ophelimus maskelli Haliday, 1844 - two new records of gall forming Eulophidae from Malta (Hymenoptera, Chalcidoidea) [PDF]

open access: yes, 2012
The Eulophidae (Hymenoptera, Chalcidoidea) currently accommodates more than 4,000 described species worldwide in some 300 genera (noyES, 2003). In Europe, the family is represented by about 1,100 species (GAuld & Bolton, 1988).
