Implication

Field ecology study reveals seasonal shifts in abundance, reproductive activity, and survivorship among female Culex tarsalis mosquitoes, highlighting temporal drivers of arbovirus transmission.

Key Points

To examine seasonal variations in relative abundance, reproductive development, and daily survivorship in a population of female Culex tarsalis mosquitoes.
Monitored relative abundance using light traps, CO2 traps, and red box shelters across the spring, summer, and fall of 1981.
Assessed reproductive status and calculated gonotrophic cycle length, nulliparous duration, and vertical daily survivorship using mark-release-recapture and laboratory observations.
Trap abundance correlated positively with ambient temperature and regional trap networks, with empty and virgin female proportions remaining steady through August before rising markedly in autumn.
The average duration of the nulliparous period was 6 days and the gonotrophic cycle averaged 4 days during summer.
Daily survivorship of resting females between May and August was estimated at 0.74 and 0.87 depending on the vertical calculation method used.
