Description
Book SynopsisThe Ichneumonoidea is a vast and important superfamily of parasitic wasps, with some 60,000 described species and estimated numbers far higher, especially for small-bodied tropical taxa. The superfamily comprises two cosmopolitan families - Braconidae and Ichneumonidae - that have largely attracted separate groups of researchers, and this, to a considerable extent, has meant that understanding of their adaptive features has often been considered in isolation. This book considers both families, highlighting similarities and differences in their
adaptations.
The classification of the whole of the Ichneumonoidea, along with most other insect orders, has been plagued by typology whereby undue importance has been attributed to particular characters in defining groups. Typology is a common disease of traditional taxonomy such that, until recently, quite a lot of taxa have been associated with the wrong higher clades. The sheer size of the group, and until the last 30 or
Trade Review
"Overall, this is a highly valuable compendium of known information, as well as currently unanswered questions, concerning ichneumonoid wasps.... Quicke is to be congratulated for producing a standard work that I, for one, will be consulting for a long time." (American Entomologist, 2016)
"This is certainly a field with many pitfalls, but there is hardly a better guide through it than Professor Quicke." (International Journal of Environmental Studies, 9 March December 2015)
"It sounds like a backhanded compliment to say that this is the best book of its kind, when I have already said that it is the only book of its kind. However, The Braconid and Ichneumonid Parasitoid Wasps goes beyond being the best of a limited field – it is a truly impressive assemblage of information on an intriguing and important group of insects. I hope that it inspires more people to work in the field." (Bulletin de la Société d'entomologie du Canada, 2015)
