Evolutionary ecology of parasitoid richness
The diversity of parasitoid wasps is enormous, but why do some hosts harbour more parasitoid species than others? Can the richness of parasitoids per host insect be predicted from host attributes, such as geographical range size, local abundance, visibility and life-cycle? By amending an existing database of host-parasitoid relations in European gall midges, patterns can be analysed. A specific hypothesis to put to the test is the Using these data to test is the "enemy hypothesis", which proposes that the galling habit has evolved to escape attack from parasitoids. This may be tested by comparing galling and non-galling midges.
