Sample size: 1598 individuals

Years: 2002 - 2005

Sampling comments: "The study was carried out during 29 months from October 2002 to February 2005... Monthly mosquito collections were carried out from 06.00 p.m. to 06.00 a.m. when landing on human beings... Two consecutive nights of mosquito collections were carried out per village and per month, in four houses, with four mosquito collectors (two inside and two outside houses) per night. Consequently, a total of 16 human-nights were performed per month in each village and the total of human-nights was 1,384 for the whole study... Exophilic resting mosquitoes were collected early after sunrise in two to five (mean 3.7 for the whole study) Muirhead-Thomson’s pit shelters per village [36] and in various resting places such as animal shelters and cart sheds. Any exophilic mosquitoes that were found were drawn up with a sucking tube. A total of 166 pit- nights and a non-registered number of other resting places were visited during the whole study."
