Determinants of parasitoid communities of willow-galling sawflies: habitat overrides physiology, host plant and space
Studies on the determinants of plant–herbivore and herbivore–parasitoid associations provide important insights into the origin and maintenance of global and local species richness. If parasitoids are specialists on herbivore niches rather than on herbivore taxa, then alternating escape of herbivores into novel niches and delayed resource tracking by parasitoids could...Nyman, Tommi ; Leppänen, Sanna ; Várkonyi, Gergely ; Shaw, Mark R ; Koivisto, Reijo …

Lestricus secalis (Linnaeus, 1758) (Hymenoptera, Braconidae): a species new to Spain parasitizing the Iberian endemic Pogonocherus sturanii (Sama & Schurmann, 1982) (Coleoptera, Cerambycidae)
The cenocoeliine braconid Lestricus secalis (Linnaeus) is recorded for the first time in Spain, being the southernmost known locality in the species’ distribution. Two specimens emerged from branches of Pinus nigra ssp. salzmannii in which the Iberian endemic cerambycid Pogonocherus sturanii was developing, in Sierra Mágina (southern Spain). Illustrated notes...Obregón, R ; Shaw, Mark R

A rearing record of Homolobus (Phylacter) meridionalis van Achterberg (Hymenoptera: Braconidae, Homolobinae) in the south of France
Homolobus (Phylacter) meridionalis is recorded parasitizing the noctuid Dryobota labecula (Esper, 1788) feeding in spring on Quercus in southern France. The adult parasitoid emerged in the autumn; evidence is presented to suggest that it is a bivoltine species, likely to parasitize low-feeding noctuids in its overwintering generation. Notes to separate...Shaw, Mark R

Cotesia acerbiae sp. nov. (Hymenoptera: Braconidae, Microgastrinae), a gregarious parasitoid of Acerbia alpina (Quensel, 1802) (Lepidoptera: Erebidae, Arctiinae in Polar Ural, Russia
Cotesia acerbiae Shaw & Vikberg sp. nov. is described from a single large brood reared from a cocoon of the circumpolar moth Acerbia alpina (Quensel, 1802) collected in Polar Ural (Tjumen oblast). The means to distinguish it from other western Palaearctic Cotesia species are given.Shaw, Mark R ; Vikberg, Veli ; Malinen, Pekka

A new Australian genus and five new species of Rogadinae (Hymenoptera: Braconidae), one reared as a gregarious endoparasitoid of an unidentified limacodid (Lepidoptera)
Teresirogas Quicke & Shaw gen. nov. (type species T. australicolorus Quicke & Shaw sp. nov.) is described and illustrated, based on a series recently reared gregariously from a cocooned mummy of an unidentified species of Limacodidae collected under loose Eucalyptus bark in New South Wales, Australia. Older reared and unreared...Quicke, Donald L J ; Shaw, Mark R ; Van Achterberg, Cornelis ; Bland, K P ; Butcher, Buntika A …

First Nearctic record of Diolcogaster claritibia (Hymenoptera: Braconidae: Microgastrinae), with notes on taxonomic status and natural history
The Microgastrinae wasp Diolcogaster claritibia (Papp, 1959) (Hymenoptera: Braconidae), a parasitoid of the diamondback moth, Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae), is recorded from the Nearctic region (Alberta, Manitoba, and Ontario, Canada) for the first time. In spite of some minor morphological and molecular (DNA barcoding) differences, the available data...Fernandez-Triana, J ; Shaw, Mark R ; Cardinal, Sophie ; Dosdall, Lloyd ; Mason, P G

Biology, early stages and description of a new species of Adelognathus Holmgren(Hymenoptera: Ichneumonidae: Adelognathinae)
Adelognathus leucotrochi Shaw & Wahl sp. nov. is described from Britain where it is a univoltine slightly gregarious koinobiont ectoparasitoid of late stage larvae of the tenthredinid sawfly Nematus leucotrochus Hartig feeding on Ribes uva-crispa. Defensive reactions by the host to prospecting females are described. The developmental biology of A.... -

First report of Cotesia vanessae (Hymenoptera: Braconidae) in North America
We report for the first time the occurrence of the well-known Eurasian and north African parasitoid Cotesia vanessae (Reinhard) (Hymenoptera: Braconidae) in North America. Specimens were reared from Chrysodeixis chalcites (Esper) and Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) recovered from several locations in southwestern Ontario, Canada, and detected by DNA sequencing...Hervet, V A D ; Murillo, H ; Fernandez-Triana, J ; Shaw, Mark R
