Morphometric analysis of two populations of Anopheles (Anopheles) calderoni (Diptera: Culicidae) from southwestern Colombia. Rev. Mex. Biodiv. [online]. 2016, vol.87, n.3, pp.966-971.

Anopheles calderoni, a species recorded in Colombia and Ecuador in 2010, is considered a malaria vector in Peru and a potential vector in the Colombian Pacific Coast. Given the recent report of A. calderoni, little is known on its morphological and genetic variability in the Colombian territory. As a first approach, this study evaluated wing morphometric variation on A. calderoni of 2 localities from western Colombia, Guadalajara de Buga and San Andrés de Tumaco. Eight morphometric characters of the wing were measured for 76 females (Buga n = 36, Tumaco n = 40) that were compared using univariate and multivariate analyzes. Pairwise comparison of wing character measures between the 2 populations showed statistically significant differences (p < .05). Discriminant analysis based on these characters, assigned with low accuracy (< 60%) each specimen to its original geographical population. Wing size differences between these A. calderoni populations may be due to micro-environmental characteristics of each locality rather than to genetic differences. The knowledge on A. calderoni population structure is relevant for the design of targeted vector control strategies.
