Malaria Research
Turning Research into Action
In 2025, Blue Sands Foundation supported the field evaluation of MOSQINOk® 0.8P, a novaluron-based larvicide tablet for mosquito larval control, in irrigated rice agroecosystems in The Gambia.
The study was conducted in two communities in the Central River Region. Janjangbureh served as the intervention community, while Sankuli Kunda served as the control community.
The evaluation included mosquito larval monitoring and adult mosquito surveillance using CDC light traps.
Blue Sands Foundation funded the fieldwork and supported project implementation and coordination.

The Challenge We Address
Irrigated rice agroecosystems can contain aquatic habitats suitable for mosquito breeding.
Larval source management can complement other approaches to malaria vector control, but interventions must be evaluated under field conditions to understand their performance in real-world environments.
Operational research helps connect scientific innovation with practical public-health implementation.
Intervention and Control Communities
Janjangbureh
Intervention Community · Central River Region · 2025
MOSQINOk® 0.8P was applied to selected aquatic mosquito habitats within the intervention study area.
Researchers conducted larval monitoring and adult mosquito surveillance to assess changes during the field evaluation.
Sankuli Kunda
Control Community · Central River Region · 2025
Sankuli Kunda served as the control community, allowing researchers to compare changes observed in the intervention area against a community where the larvicide intervention was not implemented.

MOSQINOk® Malaria Research
Janjangbureh and Sankuli Kunda · Central River Region · 2025
A controlled field evaluation found a 54.1% reduction in total mosquito larval density in the intervention area beyond the change observed in the control area.

Field Implementation
Evaluating MOSQINOk® Under Field Conditions
Larvicide Application
Field teams applied MOSQINOk® 0.8P to selected aquatic mosquito habitats within the intervention study area.
Larval Monitoring
Researchers conducted routine sampling to measure total mosquito larval density during the evaluation.
Adult Mosquito Surveillance
CDC light traps were used to monitor adult mosquito populations, including adult Anopheles mosquitoes.
Comparative Analysis
Changes observed in Janjangbureh were compared with those recorded in the control community of Sankuli Kunda.
Study Results
A Measurable Reduction in Mosquito Larvae
The principal finding was a 54.1% reduction in total mosquito larval density in the intervention area beyond the change observed in the control area.
Reductions were also observed in adult Anopheles mosquitoes. However, these reductions did not reach conventional statistical significance.
The findings provide field-based evidence concerning the use of a novaluron-based larvicide tablet for mosquito larval control in irrigated rice agroecosystems.

Scientific Achievement
From Field Evaluation to Peer-Reviewed Publication
The field evaluation was conducted in 2025. Its findings were subsequently published in the peer-reviewed journal Parasites & Vectors in 2026.

Evidence That Can Inform Practice
Field-Based Evidence
The study evaluated MOSQINOk® 0.8P under real field conditions rather than only in a controlled laboratory environment.
Comparative Study Design
Using intervention and control communities allowed researchers to assess changes beyond those observed in the comparison area.
Wider Surveillance
The study assessed both mosquito larvae and adult mosquitoes.
Knowledge Sharing
Peer-reviewed publication allows findings from The Gambia to contribute to wider scientific and public-health learning.

Where Your Support Goes
Donations to the Malaria Research programme help Blue Sands Foundation support evidence generation, field implementation and collaborative public-health research.
Funds may be used for approved research activities, field materials, monitoring, transportation, data collection, community engagement, technical support and dissemination.
Where a particular study is fully funded, Blue Sands Foundation may direct additional donations to another malaria-prevention or public-health research initiative with a similar need. This should also be explained during the donation process.
