^aCollection method included IR: Indoor-resting adult mosquitoes collected by pyrethrum-spray or aspiration; IR-bednet: blood fed and blood-seeking females collected by aspiration from net traps hung over the beds of sleeping volunteers; and HL: blood-seeking mosquitoes were collected by human landing catches.

^bRefers to the mosquito preference to feed exclusively on human blood.

^cOverall index of the intensity of malaria transmission measured as annual infective bites per person. Estimates reflect total transmission by all vector species because most studies identify An. arabiensis and An. gambiae as An. gambiae sensu lato.

^dOverall index of the intensity of lymphatic filariasis transmission based on the prevalence of mosquito infected with larvae of Wucheraria bancrofti. None refers to locals where no clinical manifestations in people are known and no infected mosquitoes were found based on personal communication Frederic Simard (Senegal) and William Hawley (W. Kenya).
