Field evaluation of BG SentinelTM traps of four different black-and-white color combinations in Mauritius for enhanced Ae. albopictus mosquito collection

摘要

The trapping efficacy of four visually modified BG SentinelTM traps (BGS traps) baited with BG LureTM were evaluated in three rural (Notre Dame, Panchvati and PDL) and one urban (Curepipe) localities in Mauritius with the aim of determining the most effective trap for Ae. albopictus surveillance. Ae. albopictus and Cx. quinquefasciatus were the dominant mosquito species collected by the BGS traps. The impact of trap color and trap location on Ae. albopictus collection differed among localities. In the rural localities, completely black BGS traps collected significantly more Ae. albopictus males while in Curepipe, no significant differences were noted among the traps. Moreover, in Notre Dame, completely black BGS traps collected significantly more Ae. albopictus females while in the other localities traps’ performance did not differ significantly. Hence, field results indicate that completely black BGS traps could be used for an optimized monitoring of Ae. albopictus in Mauritius.
