Background: , a malaria mosquito originally from South Asia and the Middle East, has been expanding across both Asia and Africa in recent decades. The invasion of this species into sub-Saharan Africa is of particular concern given its potential to increase malaria burden, especially in urban environments where thrives. Whilst surveillance of this vector in Africa has recently increased markedly there is a need to review the existing methods of control so that we can stop, rather than simply monitor, its spread in Africa.

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.

Article Synopsis
  • 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.

Sub-Saharan Africa is registering one of the highest urban population growth across the world. It is estimated that over 75% of the population in this region will be living in urban settings by 2050. However, it is not known how this rapid urbanization will affect vector populations and disease transmission.

The rapid expansion of insecticide resistance and outdoor malaria transmission are affecting the efficacy of current malaria control measures. In urban settings, where malaria transmission is focal and breeding habitats are few, fixed and findable, the addition of anti-larval control measures could be efficient for malaria vector control. But field evidences for this approach remains scarce.
