Light pollution disrupts seasonal reproductive phenotypes and reduces lifespan in the West Nile vector, Culex pipiens.

Females of the Northern House mosquito, Culex pipiens, are important disease vectors as they transmit pathogens including West Nile virus. These females survive the winter by entering diapause, a state of dormancy, characterized by the accumulation of lipids, cessation of blood-feeding, and reproductive arrest. Diapause is cued by photoperiod, so as days become short in late summer and early fall, female Cx.

Trade-offs between Winter Survival and Reproduction in Female Insects.

In temperate environments, most species of insects enter an arrested state of development, known as diapause, that enables them to survive the adverse environmental conditions associated with winter. Although diapause is restricted to a single life stage within species of insects, there are examples of insects that overwinter in the egg, larval, pupal, and adult stages. Here we offer a targeted, non-systematic literature review examining how overwintering impacts subsequent reproduction in female insects.
