Organophosphate and carbamate susceptibility profiling of Anopheles gambiae sl. across different ecosystems in southern Benin.

Background: To overcome the spread of high pyrethroid resistance in the main malaria vectors and malaria disease persistence, it is crucial to look for effective and better resistance management strategies. Understanding the phenotypic profile of against alternatives insecticides like organophosphates and carbamates is crucial.

Methods: larvae and pupae were collected from the breeding sites in rice fields, pineapple crop areas, and peri-urban areas.

Vectorial competence, insecticide resistance in Anopheles funestus and operational implications for malaria vector control strategies in Benin Republic.

The primary reason for the failure of malaria vector control across endemic regions is the widespread insecticide resistance observed in Anopheles vectors. The most dominant African vectors of malaria parasites are Anopheles gambiae and Anopheles funestus mosquitoes. These species often exhibit divergent behaviours and adaptive changes underscoring the importance of deploying active and effective measures in their control.

Investigation of DDT resistance mechanisms in Anopheles funestus populations from northern and southern Benin reveals a key role of the GSTe2 gene.

Background: Understanding the molecular basis of insecticide resistance in mosquito, such as Anopheles funestus, is an important step in developing strategies to mitigate the resistance problem. This study aims to assess the role of the GSTe2 gene in DDT resistance and determine the genetic diversity of this gene in An. funestus.

Investigating the molecular basis of multiple insecticide resistance in a major malaria vector Anopheles funestus (sensu stricto) from Akaka-Remo, Ogun State, Nigeria.

Background: Understanding the mechanisms used by Anopheles mosquitoes to survive insecticide exposure is key to manage existing insecticide resistance and develop more suitable insecticide-based malaria vector control interventions as well as other alternative integrated tools. To this regard, the molecular basis of permethrin, DDT and dieldrin resistance in Anopheles funestus (sensu stricto) at Akaka-Remo was investigated.

Methods: Bioassays were conducted on 3-5-day-old adult An.

A preliminary analysis on the effect of copper on Anopheles coluzzii insecticide resistance in vegetable farms in Benin.

The use of agrochemicals in vegetable production could influence the selection for insecticide resistance in malaria vectors. Unfortunately, there is a dearth of information on the potential contribution of agrochemicals to insecticide resistance in Anopheles mosquitoes breeding on vegetable farms in southern Benin. A Knowledge, Attitudes and Practices study was conducted with 75 vegetable farmers from Houeyiho and Seme to determine the main agrochemicals used in vegetable production, and the concentration and frequency of application, among other details.

First report of the presence of L1014S Knockdown-resistance mutation in and from Togo, West Africa.

To optimize the success of insecticide-based malaria control intervention, knowledge of the distribution of species and insecticide resistance mechanisms is necessary. This paper reported an updated data on pyrethroids/DDT resistance in the population from Togo.  From December 2013 to April 2015, females of indoor-resting were captured in three locations belonging to three different ecological zones.

Water source most suitable for rearing a sensitive malaria vector, in the laboratory.

  The insecticide susceptibility status of one of the main malaria vectors in the Afrotropical regions, remains under-studied due to the difficulty of working with this mosquito species. Collecting their larvae in natural breeding sites, rearing and maintaining them in normal laboratory conditions have been a difficult task. Forced-egg laying technique has been a very good tool to generate eggs from adult mosquitoes collected from the wild but rearing these eggs to obtain satisfying portion as adults has always been the problem.

Mapping the distribution of across Benin highlights a sharp contrast of susceptibility to insecticides and infection rate to between southern and northern populations.

Malaria remains an important public health issue in Benin, with and being the predominant vectors. This study was designed to generate information on distribution, molecular speciation, infection rate and insecticide susceptibility status across Benin. Mosquito samples were collected from December 2014 to January 2016 in 46 localities in Benin.

Evidence of a multiple insecticide resistance in the malaria vector Anopheles funestus in South West Nigeria.

Background: Knowing the extent and spread of insecticide resistance in malaria vectors is vital to successfully manage insecticide resistance in Africa. This information in the main malaria vector, Anopheles funestus sensu stricto, is completely lacking in the most populous country in Africa, Nigeria. This study reports the insecticide susceptibility status and the molecular basis of resistance of An.
