Abstract

The current study was aimed to study the importance of differed mortality recording with mosquitoes from window traps in resistance monitoring to pyrethroids in malaria vectors from mono department in south-western Benin, West Africa. An. gambiae s.l. adult mosquitoes were collected between 6.00 a.m. to 7.00 a.m in window traps put on windows of four rooms in districts of Grand Popo, Houéyogbé and Bopa surveyed in 2018. Female An. gambiae species were morphologically identified using morphological keys. The results showed that there was no dead mosquito when immediate mortality was recorded. But, after six hours, the differed mortality recording was 3.8%, 3% and 5% for mosquitoes from Grand Popo, Houéyogbé and Bopa respectively. These percentages showed that the dead of mosquitoes were not due to a product. That was likely due to tired mosquitoes as they were collected early in the morning between 6.00 a.m. and 7 a.m. and then carried out from the field to insectary. For that, it is important to record the differed mortality with mosquitoes collected in window traps before insecticide susceptibility tests performing using this mosquito sample.
