Hymenopteran parasitoids reared from European gall midges (Diptera, Cecidomyiidae).

We report the results of investigations 2010 through 2023 of hymenopteran parasitoids associated with gall midges in Europe. A total of 242 collections of gall midges were made, from each of which one to several parasitoid species emerged, resulting in ca. 200 recorded parasitoid species and 267 host-parasitoid interaction records.

New records of Chalcidoidea (Hymenoptera) from the Maltese Islands with an updated checklist.

Thirty-three species of Chalcidoidea (Hymenoptera) are newly recorded from the Maltese Islands, of which, 19 include host data. An updated checklist for the 181 chalcidoid species recorded from Malta is also included, which belong to 17 families as follows: Agaonidae (3), Aphelinidae (21, 1 as new record), Azotidae (1), Chalcididae (8 species, 5 as new records), Encyrtidae (24, 1 as new record), Eulophidae (51, 16 are new records), Eupelmidae (9, 2 as new records), Eurytomidae (6, 1 as new record), Leucospidae (4), Megastigmidae (1), Mymaridae (2), Ormyridae (1), Perilampidae (1 new record), Pteromalidae (39, 5 as new records), Signiphoridae (2), Tetracampidae (1) and Torymidae (7, 1 as new record).

Two hymenopteran egg sac associates of the tent-web orbweaving spider, (Forskål, 1775) (Araneae, Araneidae).

We report the discovery of two wasp species emerging from egg sacs of the spider (Forskål 1775) collected from mainland Spain and the Canary Islands. We identify one as (Narendran 1984) (Hymenoptera, Eurytomidae) and the other as a member of the (Walker 1839) species group (Hymenoptera, Eulophidae). This is the first report of in Europe, and the first documentation of hymenopteran egg predators of .

Rediscovery of Calymmochilus russoi Gibson, 1995 (Hymenoptera, Chalcidoidea, Eupelmidae), and revision of European Calymmochilus Masi, 1919.

The European species of Calymmochilus Masi (Hymenoptera, Eupelmidae) are revised. Calymmochilus atratus Masi stat. rev.

Checklist of British and Irish Hymenoptera - Chalcidoidea and Mymarommatoidea.

Background A revised checklist of the British and Irish Chalcidoidea and Mymarommatoidea substantially updates the previous comprehensive checklist, dating from 1978. Country level data (i.e.

Saltbush-associated Asphondylia species (Diptera: Cecidomyiidae) in the Mediterranean Basin and their chalcidoid parasitoids (Hymenoptera: Chalcidoidea).

Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were described in the late 19th century from complex bud galls on Atriplex halimus in the Mediterranean Basin. In the present study Asphondylia punica is redescribed, A.

Catalogue of parasitoids and inquilines in cynipid oak galls in the West Palaearctic.

A quantitative catalogue of the parasitoids (almost exclusively Chalcidoidea) and inquiline Cynipidae recorded in the western Palaearctic from galls induced on Quercus by Cynipidae (Cynipini) is presented. Quantitative and national data are included with bibliographic references to almost all records published in 2011 and earlier. The catalogue is followed by two checklists, firstly one of the Chalcidoidea with numbers of each species recorded from each type of host gall (galls of the sexual and asexual generations of the host gall wasps are listed separately), and secondly one of inquiline Cynipidae with host galls.

Reconstructing community assembly in time and space reveals enemy escape in a Western Palearctic insect community.

How geographically widespread biological communities assemble remains a major question in ecology. Do parallel population histories allow sustained interactions (such as host-parasite or plant-pollinator) among species, or do discordant histories necessarily interrupt them? Though few empirical data exist, these issues are central to our understanding of multispecies evolutionary dynamics. Here we use hierarchical approximate Bayesian analysis of DNA sequence data for 12 herbivores and 19 parasitoids to reconstruct the assembly of an insect community spanning the Western Palearctic and assess the support for alternative host tracking and ecological sorting hypotheses.

Concordant phylogeography and cryptic speciation in two Western Palaearctic oak gall parasitoid species complexes.

Little is known about the evolutionary history of most complex multi-trophic insect communities. Widespread species from different trophic levels might evolve in parallel, showing similar spatial patterns and either congruent temporal patterns (Contemporary Host-tracking) or later divergence in higher trophic levels (Delayed Host-tracking). Alternatively, host shifts by natural enemies among communities centred on different host resources could disrupt any common community phylogeographic pattern.
