Table 7 Field trial one: Regression coefficients with 95 % Wald confidence intervals and ∆AIC for the fixed effects of two final Bayesian general linear mixed models with a Poisson error distribution used to describe (i) the total number Culicoides collected (all species) and (ii) the number of females of potential AHSV vector species of Culicoides (Culicoides obsoletus (Meigen), 1818; Culicoides scoticus Downes and Kettle, 1952; Culicoides dewulfi (Goetghebuer), 1936; and Culicoides chiopterus (Meigen), 1830) collected in Ultraviolet (UV) Center for Disease Control (CDC) light-suction traps within frames either (i) covered with insecticide-treated mesh, (ii) covered with untreated mesh, or (iii) left uncovered
