quinquefasciatus, will not be able to transmit other diseases in the country, such as West

Nile. Currently, the vector control program does not monitor the vectors in space and time,

limiting itself to intervention measures, with intra-household spraying (PID) (deltamethrin)

for adults, and with temephos and diesel for the treatment of breeding sites. Larvivorous

fish are also used as biological control agents in irrigation water tanks [6]. Experiments

have been conducted in the country of monitoring populations of Ae. aegypti with ovitraps

[18], but it is necessary to develop and adapt tools that serve, at the same time, to monitor

and control of potential vectors in the country.

Methods that use biolarvicides (Bacillus thuringiensis israelensis (Bti)) with the BR-

OVT trap, for Culex, have proven to be efficient, safe and operationally simple [25, 26].
