  1. The proportions for each survey period are compared using generalized linear mixed models (GLMMs) with a binomial distribution, a categorical explanatory variable for study period and random factors for date and household; October 2008 formed the reference category for the GLMM.
  2. Endophagy is the proportion of mosquitoes caught indoors; nocturnality is the proportion of mosquitoes caught during hours when most people are asleep; and indoor contact is the proportion of indoor and outdoor biting rates weighted throughout the night by the proportion of humans that are typically indoors or outdoors at each time period - see Methods for details.
