The use of morphometric wing characters to discriminate female Culex pipiens and Culex torrentium.

摘要: The reliability of the length wing radial vein r2/3 as a character for morphological discrimination two potential arbovirus vectors Culex pipiens s.s. and Cx. torrentium from Germany was reassessed, after this had been neglected more than 40 years. Additionally, multivariate morphometric analyses were applied to evaluate shape variation between both species. Although high-throughput molecular tools are now available differentiate species, simple, low-cost routine alternative may be useful in absence laboratory, such under semi-field conditions. A thin-plate splines transformation confirmed that primarily shrinkage is responsible differences In bivariate analysis, r2/3/r3 indices 0.185 0.289, respectively, resulting correct classification 91% all tested specimens. Using absolute alone still allowed 90% accurate discrimination. Furthermore, accuracy linear discriminant analysis exceeded 97%.
