Lestricus secalis (Hymenoptera: Braconidae: Cenocoeliina), a genus and species new to Britain
Lestricus secalis (L.) was inadvertently listed as British on the basis of an old speculation but, as there was neither firm evidence nor the existence of any specimen, it was deleted from the British list by Shaw & Huddleston (1991). However, it was suggested by Shaw (1999) that the species...Shaw, Mark R ; Mendel, Howard

First host records for the rogadine genus Conspinaria (Hymenoptera:Braconidae)and notes on Rogadinae as parasitoids of Zygaenidae (Lepidoptera)
The parasitic wasp genus Conspinaria is recorded as parasitizing two species of chalcosiine zygaenid moths, Chalcosia thaivana owadai Wang and Erasmia pulchella hobsoni Butler in Taiwan. Parasitism of Zygaenidae and of Limacodidae by rogadine braconids is discussed in the light of possible phylogenetic relationships.Quicke, D L J ; Yen, Shen-Horn ; Mori, M ; Shaw, Mark R

Reproductive variability in Pediobius alcaeus (Walker) (Hymenoptera: Eulophidae), a parasitoid of Phyllonorycter (Lepidoptera: Gracillariidae)
Separate, but sympatric, sexual and asexual populations of Pediobius alcaceus ( Walker) (Hymenoptera: Eulophidae), a parasitoid of leaf-mining Phyllonoryter species (Lepidoptera: Gracillariidae), are shown to exist and to be associated with hosts on a different tree species in BritainShaw, Mark R ; Askew, R R

Rearing Parasitic Hymenoptera
This booklet provides information on the parasitic Hymenoptera which enable successful studies to be made of this little understood group of the British insect fauna. Details are given on the general biology of parasitic wasps, rearing principles, efficient rearing practices and detailed methods of dealing with adult wasps.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

Host ranges of parasitoids (Hymenoptera: Braconidae and Ichneumonidae) reared from Epermenia chaerophyllella (Goeze) (Lepidoptera: Epermeniidae) in Britain, with description of a new species of Triclistus (Ichneumonidae)
The complex of parasitoids attacking larval stages of Epermenia chaerophyllella in Britain is outlined, and the host range of each of the species recorded (three braconids and four ichneumonids) is discussed. `Ecological' factors, such as the behavioural similarity of unrelated hosts during the vulnerable parts of their life histories, seem...Shaw, Mark R ; Aeschlimann, J - P
