埃及伊蚊是传播登革热的蚊子，已经在亚利桑那州的许多城镇定居。确定本地Ae之间的迁移和起源。埃及伊蚊种群对于病媒控制和疾病预防很重要。用扩增片段长度多态方法推断种群的地理结构和局部亚结构，以及种群间的有效迁移率(M，每代迁移量)，并确定种群之间的遗传分化。仅在边境城镇诺加莱斯发现了人口亚结构。区域间M的可靠估计在1.02到3.41之间，区域内城市之间的M在1.66到4.44之间。总体而言，区域内城市之间的配对Phi(PT)最低。观察到的遗传分化模式表明，种群之间的迁徙并不频繁，这与人类运输促进区域间扩散的想法是一致的。
Aedes aegypti, the mosquito responsible for transmitting dengue, has colonized many cities and towns throughout Arizona. Determining both the migration between, and the origin of, local Ae. aegypti populations is important for vector control and disease prevention purposes. Amplified fragment length polymorphism was used to infer geographic structure and local substructure, and effective migration rates (M, migrants per generation) between populations, and to determine genetic differentiation between populations Three geographically and genetically differentiated groups of populations were identified. Population substructure was only detected in the border town of Nogales. Reliable estimates of M between regions ranged from 1.02 to 3.41 and between cities within regions from 1.66 to 4.44. In general, pairwise Phi(PT) were lowest between cities within regions. The observed patterns of genetic differentiation suggest infrequent migration between populations and are compatible with the idea of human transport facilitating dispersal between regions.
