Abstract

F1 progeny of field-collected Culex tarsalis Coquillett females entered diapause when larvae or young pupae were transferred from summer (25°C, 16:8 [L:D] photoperiod) to winter (18°C, 10:14 photoperiod) experimental conditions. Those transferred as older pupae or young adults failed to enter diapause and readily imbibed blood meals from restrained chicks or initiated oogenesis autogenously. The data implied that older fourth instars and perhaps young pupae are the stages sensitive to diapause induction cues. The combination of cool temperature and short daylength suppressed the expression of autogeny, enabling genetically autogenous females to undergo facultative diapause.
