Abstract
The aim of this study was to analyze the effectiveness of different control agents of Aedes aegypti and Aedes albopictus associated with ovitraps under laboratory and field conditions. Five treatments were used: grass infusion+Bacillus thuringiensis israelensis (gI+Bti), grass infusion+Saccharopolyspora spinosa (gI+Ss), grass infusion+Pyriproxyfen (gI+P), distilled water+Toxorhynchites haemorrhoidalis (dW+Th), and grass infusion (gI) (control). The highest mean number of eggs of both species were obtained with grass infusion in the laboratory. Among control agents, the lowest mean of A. aegypti eggs occurred with gI+Ss and the lowest mean of A. albopictus eggs occurred with dW+Th. There was no difference between treatments in A. aegypti (P=0.4320) and A. albopictus (P=0.7179). In the field, the highest mean number of eggs for both species were obtained with gI+Ss, and the lowest values were obtained with gI+P (P=0.0124). The treatments can be applied to both the surveillance and the control, but ovitraps with biological larvicide Bti were more effective and safer considering the number of eggs laid and selectivity of pathogens for mosquitoes.
