Efficiency of oviposition traps with biolarvicides for monitoring Aedes aegypti and Aedes albopictus (Diptera, Culicidae), northeast Brazil

Abstract

This study verified the efficiency of ovitraps combined with Saccharopolyspora spinosa and Bacillus thuringiensis israelensis for monitoring Aedes aegypti and Aedes albopictus in laboratory and field conditions. In the laboratory, for A. aegypti, there was no difference in eggs number between treatments and grass infusions. For A. albopictus, the average of eggs was higher in the grass infusion. In the dry season, there was no difference in the average of eggs between treatments and control. In the rainy season, grass infusion resulted in a higher egg density, in both areas. Ovitraps combined with biolarvicides are efficient in dengue vector monitoring.
