The black salt marsh mosquito, Aedes taeniorhynchus (Wiedemann), is widely distributed throughout the coastal areas of the American continent and important in the transmission of arboviruses such as West Nile Virus. In order to determine the genetic variability of this mosquito, we conducted a genetic study of Gulf (TX, MS, LA) and East Coast (FL, GA, NC and NY) populations. Preliminary analysis of a portion of the NADH subunit 5 mtDNA gene from NY populations resulted in two unique haplotypes. From a total of 45 specimens analyzed, 44 were haplotype 1. Haplotype diversity (hd=0.04) and nucleotide diversity (ð=0.001) observed were low. Genetic parameters that test for neutral mutation revealed population expansion or growth.
