Abstract
OBJECTIVE
To evaluate combinations of larvicides and fish which are predators of larvae of Aedes aegypti, namely Betta splendens, Trichogaster trichopterus and Poecilia reticulata.
METHODS
We used 15 water tanks with a capacity of 250 litres of water. In 10 tanks, larvicide - Temephos, Bti and Novaluron - was added, the other five contained only one specimen of fish and unchlorinated water. The fish were monitored for a week without changing the water, and their survival recorded on a form. An estimate of the Kaplan-Meier survival was performed to determine the significance of the tests.
RESULTS
Betta splendens showed the lowest mortality range of larvicides tested.
CONCLUSION
Combined use of larvivorous fish and larvicides in large water tanks is feasible.
