Background: Knowledge on the spread and distribution of insecticide resistance in major malaria vectors such as Anopheles funestus is key to implement successful resistance management strategies across Africa. Here, by assessing the susceptibility status of an inland population of An. funestus Gi...

Background The environmental pathogen, Mycobacterium ulcerans (MU) can infect both humans and animals and cause Buruli ulcer (BU) disease. However, its mode(s) of transmission from the colonized environment to human/animal hosts remain unclear. In Australia, MU can infect both wildlife and domest...


Djouaka, R.Zeukeng, F.Bigoga, J.D.Kakou-Ngazoa, S.E.Akoton, R.Tchigossou, G.Coulibaly, D.N.Tchebe, S.J.E.Aboubacar, S.Nguepdjo, C.N.Tossou, E.Adeoti, R.Ngonga, T.M.N.Akpo, Y.Djegbe, I.Tamo, M.Mbacham, W.F.Ablordey, A.[Domestic animals infected with Mycobacterium ulcerans - implications for transmission to humans]Domestic animals infected with Mycobacterium ulcerans - implications for transmission to humans

Background: Insecticides resistance in Anopheles mosquitoes limits Long-Lasting Insecticidal Nets (LLIN) used for malaria control in Africa, especially Benin. This study aimed to evaluate the bio-efficacy of current LLINs in an area where An. funestus s.l. and An. gambiae have developed multi-res...


Akoton, R.Tchigossou, G.Djegbe, I.Yessoufou, A.Atoyebi, S.M.Tossou, E.Zeukeng, F.Boko, P.Irving, H.Adeoti, R.Riveron, J.Wondji, C.S.Moutairou, K.Djouaka, R.[Experimental huts trial of the efficacy of pyrethroids/piperonyl butoxide (PBO) net treatments for controlling multi-resistant populations of Anopheles funestus s.s. in Kpomè, Southern Benin]Experimental huts trial of the efficacy of pyrethroids/piperonyl butoxide (PBO) net treatments for controlling multi-resistant populations of Anopheles funestus s.s. in Kpomè, Southern Benin

Lambda-cyhalothrin (λ-cyhalothrin) is the most commonly used pyrethroid insecticide for vegetable farming in Benin. This insecticide is misused and overused by farmers, and hence may pose health hazards to consumers. We monitored λ-cyhalothrin residues in lettuce and cabbage from farms at the mar...


Djouaka, R.Soglo, M.Kusimo, M.O.Adéoti, R.Talom, A.Zeukeng, F.Paraïso, A.Afari-Sefa, VictorSaethre, M.G.Manyong, Victor M.Tamò, M.Waage, JeffLines, J.Mahuku, George S.[The rapid degradation of Lambda-Cyhalothrin makes treated vegetables relatively safe for consumption]The rapid degradation of Lambda-Cyhalothrin makes treated vegetables relatively safe for consumption

Background. Malaria remains an important public health issue in Benin, with Anopheles gambiae s.l. and Anopheles funestus s.s being the predominant vectors. This study was designed to generate information on An. funestus distribution, molecular speciation, Plasmodium infection rate and insecticid...

Background: To optimize the success of insecticide-based malaria control intervention, knowledge of the distribution of Anopheles gambiae species and insecticide resistance mechanisms is necessary. This paper reported an updated data on pyrethroids/DDT resistance in the An. gambiae s.l population...


Djegbe, I.Akoton, R.Tchigossou, G.Ahadji-Dabla, K.M.Atoyebi, S.M.Adeoti, R.Zeukeng, F.Ketoh, G.K.Djouaka, R.[First report of the presence of L1014S Knockdown-resistance mutation in Anopheles gambiae s.s and Anopheles coluzzii from Togo, West Africa]First report of the presence of L1014S Knockdown-resistance mutation in Anopheles gambiae s.s and Anopheles coluzzii from Togo, West Africa

Metabolic resistance to insecticides such as pyrethroids in mosquito vectors threatens control of malaria in Africa. Unless it is managed, recent gains in reducing malaria transmission could be lost. To improve monitoring and assess the impact of insecticide resistance on malaria control interven...

Helicoverpa armigera is an indigenous species in Africa and has been reported in the destruction of several crops in Benin. Management of H. armigera pest is mainly focused on the use of synthetic pyrethroids, which may contribute to resistance selection. This study aimed to screen the susceptibi...

The management of the fall armyworm Spodoptera frugiperda in maize field necessitates the use a big quantities of insecticides and sometimes the use of multiple types and formulations of chemicals. The use of insecticides in crops is associated with environmental risks and health hazards to both ...
