Statistical analysis
The proportions of mosquitoes caught in the bed net trap were interpreted as host-seeking mosquitoes. The proportions were calculated by dividing the number of mosquitoes caught in the bed net trap/exit trap/resting with the total number of mosquitoes recaptured for each phenotype (resistant and susceptible mosquitoes) respectively. Observations of host seeking behavior and exit behavior of resistant and susceptible phenotypes were compared between treatments using generalized linear model (GLM) with binomial distribution and logit link function. The LLINs were considered bio-effective when the percentage of mosquitoes knocked down after 60 min post-exposure was above 95% or mortality after 24 h was above 80% in the WHO cone bioassays(WHO, 2006).Statistical analysis was done using statistical program Stata (Version 14, StataCorp, College Station, Texas).
