Effects of mosquito density on mortality and blood-feeding. The difference in the odds of mosquito mortality at 24 h (M24) or 72 h (M72) and blood feeding success (BFS) for resistant Anopheles arabiensis exposed to Interceptor® G2 or susceptible Anopheles gambiae to Interceptor® in the gold standard rabbit-100 and 50-rabbit mosquitoes *.
