  1. The abundance of host seeking mosquitoes (per night) was measured by CDC light traps placed indoors. Species composition refers to the proportion of An. arabiensis within the An. gambiae s.l. species complex. “Dev” = Deviance, and P values are for the significance of the statistical comparison between households with and without livestock.
