Field evaluation of a new light trap for phlebotomine sand flies

•A new LED trap has been tested and compared to classical model in the field.•No differences were observed between the two traps either for abundance and species.•The new trap is featured by handy design, lower weight and power consumption.•Results suggest as this new LED trap could be efficiently used in field studies.

Light traps are one of the most common attractive method for the collection of nocturnal insects. Although light traps are generally referred to as “CDC light traps”, different models, equipped with incandescent or UV lamps, have been developed. A new light trap, named Laika trap 3.0, equipped with LED lamps and featured with a light and handy design, has been recently proposed into the market. In this study we tested and compared the capture performances of this new trap with those of a classical light trap model under field conditions. From May to November 2013, a Laika trap and a classical light trap were placed biweekly in an area endemic for sand flies. A total of 256 sand fly specimens, belonging to 3 species (Sergentomyia minuta, Phlebotomus perniciosus, Phlebotomus neglectus) were collected during the study period. The Laika trap captured 126 phlebotomine sand flies: P. perniciosus (n = 38); S. minuta (n = 88), a similar number of specimens (130) and the same species were captured by classical light trap which collected also 3 specimens of P. neglectus. No significant differences in the capture efficiency at each day of trapping, neither in the number of species or in the sex of sand flies were observed. According to results of this study, the Laika trap may be a valid alternative to classical light trap models especially when handy design and low power consumption are key factors in field studies.
