Activity of Culex quinquefasciatus in an Underground Storm Drain in San Antonio, Texas

摘要

Published information on Culex quinquefasciatus Say repeatedly affirms that this species responds directly to cool temperatures by extending the length of its life cycle, rather than by interrupting development with a true state of diapause (Eldridge 1966, 1968; Wilton and Smith 1985). Observations of winter activity in populations of Cx. quinquefasciatus in Texas (Hayes and Hsi 1975, Strickman 1983) corroborate the belief that this mosquito can resume activity any time the weather warms sufficiently. This report details the work to confirm this belief. Keywords: Reprints.
