Design and evaluation of an ovitrap for the monitoring and control of Aedes aegypti, dengue fever vector

Abstract

Objective. To design and evaluate in field conditions an ovitrap with chemical attractants and a population regulator for the monitoring and control of dengue vectors. Materials and methods. CRISPP ovitrap (OC) effectiveness was evaluated in comparison with a standard ovitrap (OE). A septum containing two chemical attractants and a mesh tricot on the surface of the water was collocated in the OC. The number of eggs in both ovitraps and the mortality of the emerged adults were counted. Also the residual effect was determined. Results. There were a total of 7 168 eggs, 4 659 (65%) were layed in the OC and 2 509 (35%) in the OE and the emergence of adults in the OC was 0% compared with 93% in the OE. The residual effect was four days. Conclusions. The OC contained more eggs and caused minor emergency dengue vector adults in comparison with the OE.
