title: Observations on the D/V ratio of male genitalia of Culex pipiens complex in Amphur Muang Chiang Mai, Northern Thailand.
abstract: Mosquitoes belonging to the Culex pipiens complex were collected from various locations in Amphur Muang Chiang Mai, Northern Thailand, and identified by using D/V ratios of male genitalia. Most of the mosquitoes were Cx. pipiens quinquefasciatus, having D/V ratios of 0.46 +/- 0.09. Among these mosquitoes, 1.23% (6/490) had D/V ratios between 0.8-0.9 These forms were considered as Cx. p. quinquefasciatus which showed extreme variations from the generally acceptable criterion.
