Rediscovery of Earinus transversus Lyle (Hymenoptera:Braconidae:Agathidinae), a parasitoid of Trichopteryx polycommata (Denis and Schiffermuller) (Lepidoptera:Geometridae:Larentiinae)
Recent rearings of Earinus transversus Lyle (Hymenoptera: Braconidae: Agathidinae), a probably host-specific parasitoid of the threatened moth Trichopteryx polycommata (Lepidoptera: Geometridae), are reported from Britain. This braconid wasp should be seen as an important conservation target as it had not been recorded anywhere in the world since being described from...Shaw, Mark R

The neglect of parasitic Hymenoptera in insect conservation strategies: The British fauna as a prime example
Parasitic Hymenoptera, the major group of insects having the parasitoid life style, are extremely species rich and of wide significance in terrestrial ecosystems. Although the nature of their role with respect to species richness and stability in their host communities is unclear, the evidence that parasitoids can have a profound...Shaw, Mark R ; Hochberg, M E

Cocoon silk chemistry of non-cyclostome Braconidae, with remarks on phylogenetic relationships within the Microgastrinae ( Hymenoptera:Braconidae)
Bulk amino acid composition was determined for cocoon silks for 54 species of non-cyclostome braconid wasps collectively representing 14 subfamilies. Little intraspecific variation was encountered either between conspecific individuals of differing origin or between physically different silk layers within a single cocoon. Variation within subfamilies was small except in the...Quicke, D L J ; Shaw, Mark R ; Takahashi, M ; Yanechin, B

Molecular phylogeny of Cotesia Cameron, 1891(Insecta: Hymenoptera: Braconidae: Microgastrinae)parasitoids associated with Melitaeini butterflies (Insecta: Lepidoptera: Nymphalidae: Melitaeini)
Phylogenetic relationships among Cotesia Cameron (Braconidae) species parasitising Melitaeini butterflies were examined using DNA sequence data (mitochondrial cytochrome oxidase subunit I and NADH1 dehydrogenase genes, nuclear ribosomal DNA internal transcribed spacer region) as well as 12 microsatellite loci. Molecular data were available from ostensibly six species of Cotesia from 16...Kankare, M. ; Shaw, Mark R

Comparative morphology of the venom apparatus in the braconid wasp subfamily Rogadinae (Insecta Hymenoptera) and related taxa.
The morphology of the venom apparatus intima in representatives of 38 genera of the problematic braconid wasp subfamily Rogadinae and other cyclostome braconids was investigated and a preliminary phylogenetic analysis for the group was performed with the information obtained. Despite the limited number of characters, the data suggest several relationships...Zaldivar-Riveron, A ; Areekul, B ; Shaw, Mark R ; Quicke, D L J

Host specialization by Cotesia wasps (Hymenoptera: Braconidae) parasitizing species-rich Melitaeini (Lepidoptera: Nymphalidae) communities in north-eastern Spain
In order to investigate parasitoids of the genus Cotesia (Hymenoptera: Braconidae), larvae of a speciose group of butterflies, the tribe Melitaeini (Lepidoptera: Nymphalidae), were collected from several sites in Catalonia, northern Spain, a region that harbours ten out of the 20 European species of Melitaeini. New information on the natural...Kankare, M. ; Stefanescu, Constanti ; Van Nouhuys, Saskya ; Shaw, Mark R
