Although species are considered to be equally affected by control measures targeting malaria vectors, there is still not enough evidence of the impact of interventions such as larviciding on the distribution of these mosquito species. The present study assessed the impact of a larviciding trial targeting malaria vectors on mosquito species in the city of Yaoundé, Cameroon. A cluster randomized trial comparing 13 treated clusters and 13 untreated clusters was implemented.

- Urban malaria is a growing public health issue in Cameroon, prompting a pilot larviciding trial in Yaoundé aimed at reducing mosquito populations and malaria transmission.
- The study combined quantitative and qualitative methods to assess community perceptions on malaria control, revealing that residents in areas receiving larviciding had better knowledge of malaria transmission and mosquito breeding habits.
- Results showed that community members were generally supportive of larviciding, noticed reduced mosquito problems, and maintained regular use of bed nets, demonstrating that larviciding can be integrated into overall malaria control efforts without causing negative impacts on existing practices.
The contribution of Anopheles funestus to malaria transmission in the urban environment is still not well documented. The present study assesses the implication of An. funestus in malaria transmission in two districts, Nsam and Mendong, in the city of Yaoundé.

In the present study, the influence of house characteristics on mosquito distribution and malaria transmission risk was assessed in the city of Yaoundé.
Methods: The study was conducted from March 2017 to June 2018 in 32 districts of the city of Yaoundé.
Background: The rapid and unplanned urbanization of African cities is considered to increase the risk of urban malaria transmission. The present study objective was to assess factors influencing the spatio-temporal distribution of Anopheles gambiae s.l.

Although several free distribution campaigns of treated nets have been conducted across the country, bed net usage remains very low. A household survey was conducted to assess knowledge of the population and practices affecting treated net usage in the city of Yaoundé.

However, despite their high nuisance, they remain less studied compared to anophelines. The present study aimed to assess Culex species distribution, susceptibility to insecticide, bionomics and role in Lymphatic Filariasis (LF) transmission in the city of Yaoundé.

- * A comprehensive study conducted from March 2017 to March 2018 involved trapping and analyzing over 218,000 mosquitoes to understand their species composition, infection rates, and behavior, revealing that outdoor biting rates were considerably higher than indoor.
- * The findings indicated a high malaria transmission risk, especially outdoors, with certain mosquito populations showing resistance to key insecticides and a prevalence of genetic traits that could affect control efforts, emphasizing the need for enhanced malaria control strategies in urban settings.
