Background Despite their ecological and economic importance, hymenopteran parasitoids
are severely understudied. Even in countries with a long taxonomic history such as …

A quantitative catalogue of the parasitoids (almost exclusively Chalcidoidea) and inquiline
Cynipidae recorded in the western Palaearctic from galls induced on Quercus by Cynipidae …

A systematic study of the genus Ormyrus (Chalcidoidea, Ormyridae) was conducted based
on the morphology and biology of the terminal-instar larvae of ten west European species …

The Asian chestnut gall wasp (ACGW), Dryocosmus kuriphilus (Hymenoptera: Cynipidae), is
an invasive pest that affects chestnut trees. The first record of this pest in Spain was in 2012 …

Invasive alien species pose a challenge to ecosystem stability and crop production, so
understanding their interactions with the natural communities they invade is crucial to …

The Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky)(Coleoptera:
Cerambycidae), is a destructive invasive woodboring insect pest, and efforts are being made …

Following previous work developed on Eurytoma Illiger larvae belonging to the same
community, we study the morphology of terminal-instar larvae of five species representative …

The evolution of diverse and novel morphological traits is poorly understood, especially how
symbiotic interactions can drive these adaptations. The extreme diversity of external traits in …

Because of problems of rarity, sampling bias, and general lack of informative characters,
immature stages of parasitic Hymenoptera are seldom used to resolve phylogenetic …

As part of a wider study on the morphology and systematics of the terminal-instar larvae of
Chalcidoidea parasitoids of gall wasps (Hym., Cynipidae) in Europe, a comparative study of …
