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

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.

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

Habitat considerations for parasitis wasps (Hymenoptera)
Parasitic wasps operate at a high trophic level and, because of their biology, tend to be highly specialised, sometimes having very narrow host ranges with at least local monophagy a frequent outcome. These features, in addition to our poor state of autecological knowledge, render them particularly vulnerable in conservation terms...Shaw, Mark R

The first known parasitoid of Aricia morronensis (Ribbe, 1910), an endemic Iberian species, and notes on the parasitoids (Hymenoptera and Diptera) of the genus Aricia Rechenbach, 1817 in Europe
A parasitoid (Cotesia tenebrosa WESMAEL, 1837, Hymenoptera, Braconidae, Microgastrinae) of Aricia morronensis (RIBBE, 1910), a species endemic to the Iberian peninsula, is recorded for the first time. Incidental details, and photos of the parasitoid-host interaction are also given. Information on the parasitoids recorded from the European species of the genus...Shaw, Mark R ; Gil-T, Felipe

Polemochartus melas (Giraud) (Hymenoptera: Braconidae, Alysiinae) new to Britain
The small Palaearctic genus Polemochartus is well-known to be exclusively parasitic upon chloropid flies of the genus Lipara, which cause galls on Phragmites, ovipositing into the host's egg and killing it at the puparium stage. Hitherto, the only one of the four European species that has been found in Britain,...Shaw, Mark R ; Jennings, M T

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

Notes on the host-feeding and hyperparasitic behaviours of Itoplectis species (Hymenoptera: Ichneumonidae, Pimplinae)
Dissections of campoplegine ichneumonid prepupae in cocoons parasitised by Itoplectis maculator and I. aterrima revealed that both are truly endoparasitic in this context, and that campoplegine prepupae remain capable of movement for a time following parasitisation by these Itoplectis species. Oviposition and host-feeding behaviours by the two Itoplectis species are...Shaw, Mark R

Pseudorhacnotus enervatus, a new genus and species from Spain (Hymenoptera: Braconidae: Doryctinae)
Pseudorhaconotus enervatus gen. nov. & spec. nov. (Hymenoptera: Braconidae: Doryctinae) from Spain is described and illustrated. The new genus is similar to the genus Rhaconotus Ruthe, 1854, but differs by the lack of vein r-m of the fore wing and by the absence of dorsope on the first metasomal tergiteAchterberg, C van ; Shaw, Mark R

The taxonomy and biology of Diadegma chrysostictos (Gmelin) and Diadegma fabricianae sp. n. (Hymenoptera: Ichneumonidae)
A combination of morphological and biological evidence is used to separate two species of Ichneumonidae parasitizing Lepidoptera: Diadegma chrysostictos (Gmelin), a parasitoid of phycitine and galleriine Pyralidae, and Diadegma fabricianae sp.n. which parasitizes the choreutid Anthophila fabriciana (Linnaeus). An inbred laboratory culture of D.chrysostictos was found to be atypical with...Horstmann, K ; Shaw, Mark R

Insects and spiders on snowfields in the Cairngorms, Scotland
An account is given of seven collections of insects and spiders made in summer 1979 on snowfields above 1100m elevation in the Cairngorm mountains, Scotland. In one comprehensive collection 278 recently deposited animals representing 35 species were obtained in 25 m2; the other collections were selective. A high proportion of...Ashmole, N P ; Nelson, J M ; Shaw, Mark R ; Garside, A

Synthesis and reactions of 4-aryloxyflavans
4α-Aryloxyflavans unsubstituted in ring A have been synthesised by the reaction of phenols with flavan-4β-ols in the presence of boron trifluoride in ether. If reaction times are prolonged beyond disappearance of the starting 4β-ols, thermodynamic control leads to 4-arylflavans and the yields of 4-aryloxyflavans are negligible. 4-Arylflavans are the sole...Bateman, G ; Brown, B R ; Campbell, J B ; Cotton, C A ; Johnson, P …

The entomology of birch in Britain (and to a lesser extent in Fennoscandia) is reviewed in broad ecological terms. In particular, the size of the associated fauna, the kinds of geographical distribution patterns seen for birch insects in Britain, birch defoliators, and the conservation needs of insects associated with birch...Shaw, Mark R

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... -

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 …

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
