Abstract

Background: Malaria is an important cause of illness and death in many parts of the world, especially in sub-Saharan Africa. There has been a renewed emphasis on preventive measures at community and individual levels. 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. Objective: The current study was aimed at comparing the effectiveness of impregnated torn bed nets and non-torn untreated bed nets in the prevention of mosquito bites in malaria control. Material and methods: Eight bedrooms corresponding to eight houses were selected for adult mosquito collection in the morning in July 2025 during the great rainy season in each of two locations selected, which were Achitou and Houédjamey in Dogbo district in Couffo department. In each of these locations, four bedrooms with impregnated torn bed nets and four bedrooms with non-torn untreated bed nets were selected. Mosquitoes inside the nets were collected by electronic racket from 6 a.m. to 7 a.m in both locations. The survey was done simultaneously in both locations for fourteen consecutive nights. All collected mosquitoes were put in netted plastic cups and transferred to the Laboratory (LaRPET) for identification of Anopheles gambaie mosquitoes. Then, the physiological status of the abdomen of Anopheles gambaie mosquitoes was determined. Results: The results showed that the non-torn untreated bed nets were most effective than impregnated torn bed nets in the prevention of human-mosquito contact. Conclusion: It is important to sleep under impregnated or treated bed nets which are not torn at night. The good practice or behavior of people is important in the prevention of malaria transmission in the endemic areas of this disease.
