Fig. 4

Aedes aegypti caught in an unbaited inverted BG-Suna trap compared to a BG-Suna trap baited with CO₂, MB5 or MB5 + CO₂. Per treatment, four times 75 mosquitoes were released. Estimated marginal mean percentages are presented, assuming a binomial distribution and logit link function. Error bars represent standard errors of the mean. The asterisk (*) indicates a significant difference from a 50:50 ratio P < 0.05 (GLM: 95% CI). There were no significant covariates included in the final GLM model. The trap entry response ‘R’ is expressed as the number of mosquitoes caught in both treatments divided by the number of released mosquitoes. Significant differences in ‘R’ are indicated with letters a and b (GLM, LSD: P < 0.05)
