Ecological niche modelling of species of the rose gall wasp Diplolepis (Hymenoptera: Cynipidae) on the Iberian Peninsula

Diplolepis (Hymenoptera: Cynipidae) are gall wasps that induce conspicuous galls on Rosa spp. (Rosaceae). These species distributed globally and in Europe some especially common founder organisms of biological communities composed different insects. However, the ecological niches these have not been studied detail. We modelled potential distributions using locations four most abundant Iberian Peninsula (Diplolepis mayri, rosae, eglanteriae nervosa, latter two indistinguishable) algorithms identified resulting consensus for species. compared species, considering their spatial complementarity host plants. found D. mayri eglanteriae/nervosa complementary Peninsula. The former is Mediterranean region, while nervosa mainly Eurosiberian region. rosae has widest distribution Our models constitute first effort to identify suitable areas could be useful understanding evolutionary ecology throughout western Palearctic.
