Abstract

Malaria is a public health problem. The use of long-lasting Insecticide-Treated Bed Nets (LLINs) is the most prominent malaria preventive measure for large-scale deployment in highly endemic areas. The current study was aimed at investigating the protection conferred by torn bed nets to people in the prevention of malaria transmission. Four bedrooms corresponding to four houses were selected for adult mosquito collection in the morning in May 2025 during the great rainy season in each of two locations surveyed, which were Minontin and Sahouèkomey in the Lokossa district in Mono department. Mosquitoes inside the nets were collected by an electronic racket from 6 a.m. to 7 a.m in both locations. The survey was done simultaneously for fourteen consecutive nights (two weeks). All collected mosquitoes were put in netted plastic cups and transferred to the Laboratory of Pluridisciplinary Research of Technical Teaching (LaRPET) in Normal High School of Technical Teaching (ENSET) of Lokossa for identification of Anopheles gambaie mosquitoes. Then, the physiological status of the abdomen of Anopheles gambaie mosquitoes was determined. The results showed that the mosquitoes collected in bedrooms where impregnated mosquito nets were torn were higher than those collected in bedrooms where impregnated mosquito nets were not torn. No gravid mosquitoes were found in the collected mosquito fauna. The physical barrier of Long Lasting Insecticidal Nets (LLINs), which are frequently distributed free by Beninese National Malaria Control Program throughout the entire country to increase coverage of LLINs, is still important. It is important to sleep under impregnated mosquito bed nets that are not torn at night.
