The suitability of clay pots for indoor sampling of mosquitoes in an arid area in northern Tanzania

Water storage clay pots have been recently explored as method for outdoor mosquito sampling and as novel device for administrating insect-pathogenic fungi to mosquitoes. Their suitability for indoor mosquito sampling in natural conditions is unknown. We tested clay pots as indoor resting sites alongside catches by CDC light trap in an area of low malaria endemicity in northern Tanzania. Mosquitoes were caught by clay pots although the rate of female Anopheles mosquito catches was 22.64 (95% CI 11.26–45.52) times greater for CDC light traps. The proportion of fed female Anophelines was significantly higher for clay pots compared to CDC light trap (p
