As part of a tour of his constituency, the sub-prefect of Bankim District visited the CRID experimental field station. This visit took place on November 28, 2017. For the sub-prefect, this descent was intended to get acquainted with the activities carried out within the structure and also to support this structure which helps to evaluate the performance of the insecticide-based tools used to reduce malaria transmission such as Long Lasting Insecticidal Nets.
The experimental station in Mibellon village in Bankim district, Adamawa region has 12 huts. built according to the latest standards prescribed by the World Health Organization (WHO). These huts are used to test the effectiveness or performance of vector control tools in semi-natural conditions. These tools may be long-lasting insecticidal nets (LLINs) or formulations for indoor residual spraying (IRS).
The actual visit took place in two stages. Firstly, the visit to the booth where the mosquito collection equipment was displayed in the houses, this was an opportunity for us to present to the sub-prefect and his suite our different mosquito collection techniques in the houses for our research activities. Secondly, we visited the experimental huts explaining the different parameters and methods used to test the effectiveness of the nets. Our activities in the villages of Mibellon consist mainly of mosquito collection in the houses for different research activities and the use of the experimental huts for the evaluation of new insecticides.
Much of our work involves investigating Anopheles funestus and Mibellon is one of the localities in Cameroon where Anopheles funestus is the predominant species. This species constitutes at least 80% of Anopheles populations collected in the area (Menze et al, unpublished data).
The Cameroonian government in its efforts to reduce the transmission of malaria has undertaken a massive distribution of LLINs in recent years. 70.9% of households in Cameroon hold LLINs and 47.5% of households sleep under LLINs (CMI, 2014). However, the effectiveness of these tools for combating malaria is threatened by the emergence of insecticide resistance in African countries and in Cameroon in particular (GPRM, 2012) (Menze et al., 2016). Therefore, it is necessary to design and implement appropriate resistance management strategies to maintain the effectiveness of LLINs and IRS. The use of experimental huts is one of the best approaches used to evaluate the impact of resistance on the effectiveness of these tools.
