Impact of bait on mortality and blood-feeding adjusted for the net condition. The difference in the odds of mosquito mortality at 24-h (M24) or 72-h (M72) and blood feeding success (BFS) for 100 pyrethroid-resistant Anopheles arabiensis exposed to Interceptor® and Interceptor® G2 with either a rabbit, human arm or membrane feeder as bait *.
