Mosquito Collections and Malaria Vector Dynamics Around the Soum Dam, Burkina Faso

11,378 Anopheles mosquitoes were collected from five villages near the Soum Dam in Burkina Faso between March 2022 and February 2023. The dataset, created by Hamidou Ilboudo and shared on figshare, characterizes species composition, blood meal sources, and Plasmodium falciparum sporozoite infection rates. It aims to understand how dam construction influences mosquito ecology and malaria transmission.

Use Cases

• Modeling the relationship between distance from a dam and vector density based on collection data from five villages.
• Analyzing species-specific anthropophilic behavior based on PCR-identified blood meal sources.
• Comparing sporozoite infection rates across different Anopheles species and geographic locations.
• Studying seasonal transmission dynamics using monthly collection data spanning a full year.

Strengths

• Contains data on 11,378 individual mosquitoes, providing a substantial sample for analysis.
• Includes detailed species breakdowns, such as 86.5% An. gambiae s.l. and 91.5% of that complex being An. coluzzii.
• Reports specific metrics like an overall sporozoite rate of 6.2% and human blood meal rate of 34.7%.
• Covers a full annual cycle with monthly collections from March 2022 to February 2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific five villages studied.
