Braconid and ichneumonid (Hymenoptera) parasitoid wasps of Lepidoptera from the Maltese Islands
Fourteen species of Ichneumonidae are here recorded from the Maltese Islands. Of these, all were reared from Lepidoptera hosts with the exception of Netelia (Paropheltes) inedita (Kokujev) which was collected from a malaise trap. Of these, the following species (or genera) are here reported for the first time from the...Mifsud, David ; Farrugia, Lucia ; Shaw, Mark R

Two examples of anterior / posterior gynandromorphism in Ichneumonidae (Hymenoptera)
Two specimens of Ichneumonidae exhibiting interior/posterior gynandromorphism are described. In both the specimens of Ephialtes manifestator (L.) (Ichneumonidae: Pimplinae) and Cylloceria sylvestris (Gravenhorst) (Ichneumonidae: Cylloceriinae), the head is female (as is the mesosoma of E. manifestator) and the metasoma is male. A potential mechanism for generation of transverse (anterior/posterior) gynandromorphs...Shaw, Mark R ; Broad, Gavin R

Notes on the biology, morphology and generic placement of “Hellwigia” obscura Gravenhorst (Hymenoptera: Ichneumonidae, Ophioninae)
The ophionine ichneumonid known as Hellwigia obscura has been reared for the first time, from larvae of Horisme sp. (Lepidoptera: Geometridae) feeding on Clematis vitalba in The Netherlands. The cocoon and the parasitoid’s means of emergence are figured, as are some features of the adult. On a balance of morphological...Shaw, Mark R ; Voogd, Jeroen

Overwintering behaviour of Diphyus quadripunctorius (Müller) (Hymenoptera: Ichneumonidae, Ichneumoninae) in south-east Scotland
Overwintering behaviour of adult females of the ichneumonid Diphyus quadripunctorius (Müller) in caves and mines in south east Scotland was monitored over two successive winters. This is a univoltine larva-pupal parasitoid of certain Noctua species, parasitizing their larvae in spring. The species was found in rather few of the sites...Baird, Katty ; Shaw, Mark R

Ichneumonid wasps (Hymenoptera: Ichneumonidae): their classification and biology
The hymenopteran family Ichneumonidae compriises one of the largest single animal families. With around 2,300 British species, almost 10% of British insect species are ichneumonids. They can be found everywhere and studying them is very rewarding, but it is not without its difficulties. This book provides an extensively illustrated key...Broad, Gavin R ; Shaw, Mark R ; Fitton, M G

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 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

Parasitoid communities: their size, structure and development
In this chapter the authors first consider the literature on host-parasitoid associations and its limitations. They then review ideas that have been applied to the study of parasitoid communities. The authors develop a system of categorizing parasitoids, based on a fundamental dichotomy in their biology, which allows them to make...Askew, R R ; Shaw, Mark R

The Hymenoptera associated with spiders in Europe
The Hymenoptera known to be obligatory parasitoids or predators of spiders or their eggs in Europe form a rather diverse assemblage. Their biologies are briefly reviewed; known host associations are summarized for each genus; and a key is given to the genera of Hymenoptera (other than Pompilidae) involved.Fitton, M G ; Shaw, Mark R ; Austin, A D

Seasonal variation in the reproductive strategy of the parasitic wasp Eulophus larvarum (Hymenoptera: Chalcidoidea: Eulophidae)
1. Eulophus larvarum (L.) (Hymenoptera: Eulophidae) is a gregarious parasitoid of lepidopterous larvae feeding on broad-leaved trees. Normally there are two generations a year. 2. Sex ratio in the spring generation of larvae is female biased. The bias is probably due to local mate competition as progeny from one brood...Godfray, H C ; Shaw, Mark R

The biology, egg and larvae of Acaenitus dubitator (Panzer) (Hymenoptera, Ichneumonidae: Acaenitinae)
Acaenitus dubitator (Panzer) is found to be a koinobiont endoparasitoid of the larva of an endophytic beetle, Cleonis piger (Scopoli) (Curculionidae), in Britain, suggesting a similar mode of development for the ichneumonid subfamily Acaenitinae as a whole. The parasitoid can overwinter in its cocoon in one of two ways. Individuals...Shaw, Mark R ; Wahl, D B

Influences of host feeding-niche and foodplant type on generalist and specialist parasitoids

The majority of parasitoid species of exophytic (internally feeding)...Hawkins, B A ; Askew, R R ; Shaw, Mark R

Relations among assemblage size, host specialization and climatic variability in North American parasitoid communities
We classified the parasitoids attacking 628 species of North American herbivorous insects as idiobionts (those that permanently disable their host during attack) or koinobionts (those that permit continued host development following parasitization). Using these physiological attributes of parasitoids as estimators of host range, we tested three hypotheses that might explain...Hawkins, B A ; Shaw, Mark R ; Askew, R R
