Summary
A new updraft trap effectively samples sandflies from animal burrows in Kenya, providing consistent results. This trap aids in understanding sandfly populations and disease vector distribution.
Area of Science:
- Medical entomology
- Vector-borne disease research
Background:
- Sandflies are vectors for leishmaniasis.
- Accurate sandfly sampling is crucial for disease control.
Purpose of the Study:
- To develop and evaluate an updraft trap for sandfly sampling.
- To compare the updraft trap's efficacy with existing methods.
- To analyze sandfly species composition and sex ratios.
Main Methods:
- Development of a novel updraft trap using a plastic pipe, electric motor, fan, and collection cage.
- Field testing in Marigat, Kenya, comparing the updraft trap with CDC and sticky traps.
- Collection and identification of sandflies, with analysis of species and sex distribution.
Main Results:
- The updraft trap demonstrated greater consistency in sampling sandflies from animal burrows compared to CDC and sticky traps.
- Eleven sandfly species were identified, with Sergentomyia bedfordi and Phlebotomus martini being the most abundant.
- Different traps showed variations in species composition and sex ratios, with CDC traps attracting known leishmaniasis vectors.
Conclusions:
- The developed updraft trap is a reliable tool for consistent sandfly sampling, particularly from burrows.
- Trap efficacy influences the capture of specific sandfly species and their sex ratios.
- Findings contribute to understanding sandfly ecology and leishmaniasis transmission dynamics in the study area.
