“…The lack of a seasonal crossover in the wetland sites is likely driven by the cooler and wetter conditions in these areas that are more favorable to Cx. restuans mosquitoes (Madder et al, 1980(Madder et al, , 1983Small, 2006). Importantly, although WNV activity increased in Cx.…”

“…47,48 For this population, fall and winter development required about 200 daydegrees ( C) above a base of 7 C, which was different from the day-degree model calculated for Cx. pipiens from experimental data by Madder and others 49 in southern Ontario. That study found that development from hatching to emergence required 132 day-degrees with a base temperature of 9.4 C. The difference in day-degree models could be the result of genetic differences between the populations, with the California population able to develop successfully under suboptimally cool temperature conditions that would not be experienced by diapausing populations in Ontario.…”

Abstract. We surveyed the genetic ancestry and recorded the occurrence of autogeny, the developmental times, and survival rates in families of Culex pipiens in Santa Clara County, CA, at 37 N latitude. Females in 95% of the families produced fertile egg rafts without access to blood (= autogeny) after mating in stenogamous conditions. Developmental time, survival, and egg raft production were closely correlated to temperature. Male DV/D ratios overwhelmingly matched Cx. pipiens but a microsatellite analysis revealed these were Cx. pipiens form molestus hybridized with Culex quinquefasciatus and to a lesser extent to Cx. pipiens form pipiens, a genetic mix heretofore not recorded elsewhere. Greater DV/D ratios and larger proportions of genetic ancestry from Cx. quinquefasciatus were negatively correlated to autogeny. The combination of multiple overwintering strategies and widespread autogeny in females arising from aboveground larval sites supports the hypothesis that some North American populations of Cx. pipiens complex mosquitoes express unusual phenologies.

“…In particular, vector development and survival, and arbovirus replication are greatly influenced by temperature. In mosquito vectors, temperature can influence larval development time, larval and adult survival, biting rates, gonotrophic cycle lengths, and vector size (Madder et al 1983, Rueda et al 1990, Scott et al 1993. Ambient temperature can affect arboviral dynamics within the mosquito vector by altering the length of the extrinsic incubation period (EIP), which is the time between ingestion of an infectious blood meal and when transmission to a subsequent host is possible (Chamberlain and Sudia 1955, Reeves et al 1994, Patz et al 1996.…”

A key feature in the recent widespread epidemic of the mosquito-borne alphavirus chikungunya virus (CHIKV) was the important role of Aedes albopictus, formerly regarded as a secondary vector, compared to the presumed primary vector Aedes aegypti. Ae. albopictus, a container-inhabiting mosquito, is an invasive species that occurs over a wide geographic range spanning tropical and temperate latitudes. In this study we examine the effects of a broad range of larval rearing temperatures on CHIKV infection, dissemination, and viral titer in Florida F(1) Ae. albopictus. Adults from larvae reared at 18 degrees C, 24 degrees C, and 32 degrees C differed significantly in size, development time, and CHIKV infection rate. Adult females with the largest body size were produced from the coolest temperature, took the longest to mature, and six times more likely to be infected with CHIKV than females reared at 32 degrees C. There was also a significant effect of rearing temperature on viral dissemination, resulting in an increase in population dissemination at the coolest temperature. This study indicates that climate factors, such as temperature, experienced at the larval stage, can influence the competence of adult females to vector arboviruses.
