The use of traps can contribute to both the monitoring and reduction in population densities of mosquitoes 18 – 25. However, no method is employed to evaluate control measures targeting this mosquito, unlike the National Program for Dengue Control (PNCD), which promotes control actions targeting Aedes aegypti and describes evaluation methods for such actions 17. quinquefasciatus is addressed in the National Plan for the Elimination of Filariasis 16. Moreover, the mapping and treatment of preferential breeding sites for C. In the State of Pernambuco (Northeastern region of the country), the municipalities of Recife, Olinda, and Jaboatão dos Guararapes have developed control actions since 2002 as part of the Global Programme to Eliminate Lymphatic Filariasis 14 ),( 15. quinquefasciatus is determined based on local needs 14 ),( 15. Dense populations of this mosquito are found in urban areas that present artificial breeding sites such as pits, open ditches, and sewage, with large amounts of organic matter, where mosquito females prefer to lay their eggs 1 ),( 11 ),( 12. However this mosquito is distributed throughout the world and its occurrence is associated with urban areas with precarious conditions of environment and sanitation. quinquefasciatus is frequent and abundant 1 ),( 11 ),( 13. In addition, this species causes great nocturnal discomfort because of the preference of its females to feed on blood at night 1 ),( 11 ),( 12.Įspecially in regions with tropical climates, where temperature and precipitation rates are high, the presence of C. Zika virus has also recently been found in the salivary glands of this mosquito 9 ),( 10. Whereas other outcome measures include the change in density threshold of Aedes and changes in dengue-related knowledge, attitude and practice among cluster inhabitants.Culex quinquefasciatus is a mosquito with vector competence for the transmission of different pathogens, such as arthropod-borne viruses in the families Flaviviridade (Saint Louis encephalitis virus 1 and West Nile virus 2 – 4) and Bunyaviridae (Oropouche virus 5 ),( 6), as well as worms that cause lymphatic filariasis 7 ),( 8.
The primary outcome concerns the the percentage change in the (i) number of dengue cases and (ii) durations of dengue outbreaks. When a dengue-positive mosquito is detected, the community will be advised to execute vector search-and-destroy and protective measures. GOS traps are set at the apartments to collect Aedes weekly, following which dengue NS1 antigen is detected in these mosquitoes. Eight residential apartments were randomly assigned into intervention and control arms.
#New sticky gravid traps trial#
A parallel, cluster, randomized controlled, interventional trial is being conducted for 18 months in Damansara Damai, Selangor, Malaysia, to determine the efficacy of using gravid oviposition sticky (GOS) trap and dengue non-structural 1 (NS1) antigen test for early surveillance of dengue among Aedes mosquitoes to reduce dengue outbreaks.
