Spatio-temporal impacts of aerial adulticide applications on populations of West Nile virus vector mosquitoes.

ABSTRACT:

Background

Aerial applications of insecticides that target adult mosquitoes are widely used to reduce transmission of West Nile virus to humans during periods of epidemic risk. However, estimates of the reduction in abundance following these treatments typically focus on single events, rely on pre-defined, untreated control sites and can vary widely due to stochastic variation in population dynamics and trapping success unrelated to the treatment.

Methods

To overcome these limitations, we developed generalized additive models fitted to mosquito surveillance data collected from CO₂-baited traps in Sacramento and Yolo counties, California from 2006 to 2017. The models accounted for the expected spatial and temporal trends in the abundance of adult female Culex (Cx.)
