Fig. 2From: Field-based assessments of the seasonality of Culex pipiens sensu lato in England: an important enzootic vector of Usutu and West Nile virusesSeasonal change in trap-catch of Cx. pipiens s.l./torrentium at ZSL from 2014 to 2018 and at CZ from 2017 to 2019 and in 2021. Female mosquitoes were caught using Biogents-Mosquitaire (MQ) traps. Data generated for ZSL were obtained using a zero-inflation negative binomial model derived from the observed yield from 2014 to 2018, while data from CZ were derived from a negative binomial model as excess zeros were not observed in the CZ dataset.
