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

Parasitoid assemblages reared from geometrid defoliators (lepidoptera: geometridae) of larch and fir in the alps
1 Geometrid larvae were collected from larch and fir in the Swiss Alps in 1991–94. Eight geometrid species were found in sufficient numbers to rear out parasitoids: Agriopis aurantiaria, Bupalus piniarius, Epirrita autumnata, Eupithecia lariciata, Odontopera bidentata, Lycia isabellae and Semiothisa liturata were collected from larch, and Puengeleria capreolaria was obtained...Kenis, M. ; West, R.

Suspended mummies in Aleiodes species (Hymenoptera: Braconidae: Rogadinae) with descriptions of six new species from western Uganda based largely on DNA sequence data
A group of species of the rogadine braconid genus Aleiodes are shown to produce a distinctive mummy, which is “J”-shaped and is formed after the host larva, in all cases an ennomine geometrid moth, has dropped from a plant suspended in midair by a silk thread. The group includes one...Quicke, D L J ; Mori, M ; Zaldivar-Riveron, A ; Laurenne, N M ; Shaw, Mark R

First host records for the rogadine genera Rogasodes Chen & He and Canalirogas van Achterberg & Chen (Hymenoptera: Braconidae) with description of a new species and survey of mummy types within Rogadinae s. str
The parasitic wasp genus Rogasodes is recorded for the first time outside mainland China, based on a new species, R. scytaloptericola Quicke and Shaw sp. nov., from Java. Rearing data and host remains associated with the type specimen show that it is a parasitoid of the palm-feeding drepanid moth, Scytalopteryx...Quicke, D. L. J. ; Shaw, Mark R

A new subgenus of the genus Colastes Haliday (Hymenoptera: Braconidae) for species reared from bracket fungi, with description of two new species from Europe
A new Holarctic subgenus (Fungivenator subgen. nov.) of the genus Colastes Haliday, 1833 (Hymenoptera: Braconidae: Exothecinae) is proposed for a group of species that, as far as is known, has its larvae living on hosts in bracket fungi. The type species (Colastes sandei sp. nov. from Netherlands, Germany and England)...Achterberg, C van ; Shaw, Mark R

The identity of Scambus planatus (Hartig, 1838) and Scambus ventricosus (Tschek, 1871) as seasonal forms of Scambus calobatus (Gravenhorst, 1829) in Europe (Hymenoptera, Ichneumonidae, Pimplinae, Ephialtini)
Through both natural and experimental rearings, supported by DNA sequence data (CO1, ITS2 and EF1α) as well as examination of material in collections, it is shown that the European nominal taxa Scambus planatus and Scambus ventricosus comprise the spring-emerging generation of Scambus calobatus, the typical form of which occurs as...Shaw, Mark R ; Jennings, M T ; Quicke, D L J

Wolbachia and DNA barcoding insects: patterns, potential and problems
Wolbachia is a genus of bacterial endosymbionts that impacts the breeding systems of their hosts. Wolbachia can confuse the patterns of mitochondrial variation, including DNA barcodes, because it influences the pathways through which mitochondria are inherited. We examined the extent to which these endosymbionts are detected in routine DNA barcoding,...Smith, M A ; Bertrand, C ; Crosby, K ; Eveleigh, E S ; Fernandez-Triana, J …

Parasitism and migration in southern Palaearctic populations of the painted lady butterfly, Vanessa cardui (Lepidoptera: Nymphalidae)
The painted lady butterfly (Vanessa cardui) (Lepidoptera: Nymphalidae: Nymphalinae) is well known for its seasonal long-distance migrations and for its dramatic population fluctuations between years. Although parasitism has occasionally been noted as an important mortality factor for this butterfly, no comprehensive study has quantified and compared its parasitoid complexes in... -

Escape from natural enemies during climate-driven range expansion: a case study
A major, and largely unexplored, uncertainty in projecting the impact of climate change on biodiversity is the consequence of altered interspecific interactions, for example between parasitoids and their hosts. The present study investigated parasitism in the Brown Argus butterfly, Aricia agestis; a species that has expanded northward in Britain during...Menéndez, Rosa ; González-Megías, Adela ; Lewis, Owen T ; Shaw, Mark R ; Thomas, Chris D.
