Analysis of the Relationship Between Density and Dominance of Anopheles minimus (Diptera: Culicidae) with Environmental Parameters in Southern Yunnan Province, Peoples Republic of China

Abstract

The association of environmental factors with uctuations in the density of the malaria vector Anopheles minimus (Theobald, 1901) was analyzed in Longtang and Dongfanghong, two villages in southern Yunnan Province, Peoples Republic of China. The distance of trap locations to rice elds and the distance from trap locations to rivulets were negatively correlated to the density of An. minimus. The length of a rivulet within a 1-km buffer around a trap location was positively correlated to the density of An. minimus, whereas the rice eld area within a 1-km buffer of a trap location was negatively correlated to An. minimus dominance, but the length of a rivulet within a 1-km buffer around a trap location and the distance of trap locations to rice elds were positively correlated to An. minimus dominance. Linear models relating the density and dominance of An. minimus at trap sites in relation to environmental parameters are described. These results could help in the design of malaria control strategies.
