First record of Pteromalus varians (Hymenoptera: Pteromalidae) parasitizing on Tischeria ekebladella (Lepidoptera: Tischeriidae) in Hungary [PDF]

open access: yes, 2014
Pteromalus varians (Spinola, 1808) is fi rstly recorded from Quercus leaves, mined by the trumpet leafminer moth Tischeria ekebladella (Bjerkander, 1795) in forests near Budapest, Hungary. A total of 392 parasitoids were reared in laboratory conditions,

Evolving perspectives in Hymenoptera systematics: Bridging fossils and genomes across time

open access: yesSystematic Entomology, Volume 50, Issue 1, Page 1-31, January 2025.
Advances in sequencing and phylogenomic methods reveal unresolved deep phylogenetic nodes with variable age estimates in Hymenoptera, including, for example, Eusymphyta and Proctotrupomorpha. Conflicting morphological and molecular data hinder consensus in Hymenoptera systematics.

The usefulness of chromosomes of parasitic wasps of the subfamily Eupelminae (Hymenoptera: Chalcidoidea: Eupelmidae) for subfamily systematics

open access: yesEuropean Journal of Entomology, 2008
Karyotypes of 16 Eupelminae species were analyzed. The haploid chromosome number was found to be much more diverse than the n = 5 previously recorded for three studied species.

Temporal changes in the composition of parasitoid assemblages associated with the invasive chestnut gall wasp

open access: yesEcological Entomology, Volume 49, Issue 6, Page 779-797, December 2024.
After 4‐year monitoring of Dryocosmus kuriphilus, we found that the abundance of each associated parasitoid species varied over time and that the number of species increased year after year. Changes in the number of parasitoid species associated with D.

Poor control of the horse chestnut leafminer, Cameraria ohridella (Lepidoptera: Gracillariidae), by native European parasitoids: a synchronisation problem

open access: yesEuropean Journal of Entomology, 2004
Horse chestnut trees in many regions of Europe have suffered from epidemic infestations of C. ohridella for more than ten years. There has been no obvious decrease in the infestation level anywhere on the continent. One reason is, that the native natural

Two ways of finding a host: A specialist and a generalist parasitoid species (Hymenoptera: Chalcidoidea: Pteromalidae)

open access: yesEuropean Journal of Entomology, 2011
Two closely related parasitoid wasp species with different host specificities were used for experimental studies on the biology of host finding, a crucial element of parasitoid life history: The habitat and host specialist Nasonia vitripennis and the ...

Phenology and sex ratio of the parasitoids of a cereal leaf miner Chromatomyia fuscula (Diptera: Agromyzidae)

open access: yesEuropean Journal of Entomology, 2000
The univoltine leaf miner Chromatomyia fuscula Zetterstedt is a Scandinavian cereal pest. We wanted to compare the phenology of C. fuscula in southern Norway with that of its most important natural enemies: 15 parasitoids of the families Eulophidae and ...
