ABSTRACT

Background: Mouth aspirator is usually used for adult malaria vector collection. This sampling is necessary for entomological researches. Objective: The current study was aimed to compare two tools for mosquito residual fauna collection: mouth aspirator and electronic racket. Methodology: Four bedrooms were selected for adult mosquito collection in the morning in July 2020 during the rainy season in three different districts in Mono department such as Grand Popo, Houéyogbé and Bopa districts. Mosquitoes resting in the houses were collected by two ways. By mouth aspirator after using indoor pyrethrum spray catches (PSC) in the morning in two houses of each district and by electronic racket in two houses of each district from 6 a.m. to 7 a.m. The survey was done simultaneously in the three districts for ten consecutive nights. All collected mosquitoes were put in netted plastic cups and transferred to the Laboratory for identification. Results: The results show that many mosquito species were present in Mono department such as: Anopheles gambiae, Anopheles funestus, Anopheles pharoensis, Culex quinquefasciatus, Culex decens, Culex nebulosus, Aedes aegypti and Mansonia Africana. The number of mosquito species collected by electronic racket in the different districts surveyed were higher than those collected by mouth aspirator. Conclusion: There are many advantages in the use of electronic racket for the morning collection of mosquito resting in the human houses. The electronic racket is new, important and effective tool for the collection of mosquito resting in the human houses. It is a complementary tool to the traditional mouth aspirator.
