Bio-efficacy of Olyset Plus, PermaNet 3.0 and Interceptor G2 on pyrethroid-resistant populations of Anopheles gambiae s.l. prior to the June 2023 net distribution campaign in Benin, West Africa.

Background: This study investigates the effectiveness of new-generation mosquito nets, like Olyset Plus and PermaNet 3.0, and dual-action nets such as Interceptor G2, against pyrethroid-resistant Anopheles gambiae mosquitoes following the 2023 mass distribution of long-lasting insecticidal nets in Benin.

Methods: We tested wild mosquito populations from six communes in Benin against various pyrethroid (permethrin 0.

Detection of DENV-1, DENV-3, and DENV-4 Serotypes in and , and Epidemic Risk in the Departments of Oueme and Plateau, South-Eastern Benin.

This study conducted in the departments of Oueme and Plateau aims to assess the presence of the dengue virus and its different serotypes in and , as well as the epidemic risk incurred by the populations. Collections of adult mosquitoes using human landing catches (HLC) were carried out in six communes, three (Porto-Novo, Adjarra, and Avrankou) in the Oueme department and the rest (Ifangni, Kétou, and Pobè) in the Plateau department. Pools of ten mosquitoes were formed, and stored at -80°C in RNA later.

Malaria transmission potential of Anopheles gambiae s.l. in indoor residual spraying areas with clothianidin 50 WG in northern Benin.

The study objective was to assess the frequency of the kdr-L995F and ace-1 G280S genetic mutations in Anopheles gambiae s.l. mosquitoes and examine their ability to transmit Plasmodium falciparum in areas where indoor residual spraying (IRS) was implemented with Clothianidin 50 WG.

Presence of Plasmodium vivax in Anopheles gambiae and absence in other malaria vectors in Cove-Zagnanando-Ouinhi health zone in southern Benin, West Africa.

Background: Malaria remains a major public health problem in sub-Saharan Africa, particularly in Benin. The present study aims to evaluate the different Plasmodium species transmitted by malaria vectors in the communes of Cove, Zagnanado and Ouinhi, Southern Benin.

Methods: The study was conducted between December 2021 and October 2022 in 60 villages spread over the three study communes.

Distribution and Abundance of and (Diptera: Culicidae) in Benin, West Africa.

Updated information on the distribution and abundance of and is crucial to prepare African countries, such as Benin, for possible arboviral disease outbreaks. This study aims to evaluate the geographical distribution, abundance and biting behaviour of these two vectors in Benin. Three sampling techniques were used in this study.
