Introduction: Culex quinquefasciatus is a mosquito of importance to public health, as it represents a potential risk for the transmission of pathogens to humans, such as some arthropod-borne viruses and nematodes that cause filariasis. In Brazil, three municipalities in Pernambuco (state of Northeast of Brazil) that are endemic for lymphatic filariasis conducted control actions targeting this vector. With the aim of contributing novel C. quinquefasciatus collection strategies, a sticky trap capable of collecting eggs and imprisoning mosquitoes was investigated.
Methods: We adapted the oviposition BR-OVT trap to collect culicids eggs and adult C. quinquefasciatus and evaluated the performance of the sticky BR-OVT trap in two neighborhoods of Olinda-PE-Brazil (Caixa d’Água and Passarinho) between August 2011 and June 2012. Sixty traps were installed in the indoor areas of residences in the two districts.
Results: During the 11-month study, more than 100 Culex egg rafts, 1,430 C. quinquefasciatus. Additionally, 363 Aedes mosquitoes were caught by sticky BR-OVT traps. In these collections, female specimens were predominated in the traps: 59% of C. quinquefasciatus and 96% of Aedes spp. Conclusions: The results demonstrated that the sticky BR-OVT trap is a useful tool for the collection of adult culicids of medical importance and offers an innovative way to collect C. quinquefasciatus eggs and adults in a single trap.
