Transmitted Light as Attractant with Mechanical Traps for Collecting Nocturnal Mosquitoes in Urban Bangkok, Thailand

ABSTRACT Mosquito surveillance is the cornerstone for determining abundance, species diversity, pathogen infection rates, and temporal spatial distribution of different life stages in an area. Various methods are available assessing adult mosquito populations, including mechanical trap devices using forms attractant cues (chemical visual) to lure mosquitoes trap. So-called “light traps” use various electromagnetic wavelengths produce a variety visible spectral colors attract mosquitoes. However, this type trapping technology has not been widely used Thailand. This study compared efficacy 4 light-emitting diodes (LEDs) (blue, green, yellow, red) 2 fluorescent (ultraviolet [UV] white) lights collecting urban Bangkok. Using Latin square experimental design, 6 light traps equipped with were rotated between site locations within Kasetsart University (KU) campus. Each location received replicate collections (6 consecutive trap-nights represented 1 replicate) over 36 collection nights total 216 trap-nights. Traps operated simultaneously (1800 0600 h), captured removed at 3-h intervals. In total, 2,387 consisting 11 across 5 genera (Aedes, Anopheles, Armigeres, Culex, Mansonia) captured. Collectively, Culex predominant group sampled (2,252; 94.4%). The UV source 1,544 (64.7%) collected, followed by white 389 (16.3%), LED sources 6.8% (blue) 1.9% (yellow). clearly most effective capturing nocturnally active on KU
