What is it about?

The study evaluates the efficacy of the chemical larvicide Temephos for the control of potential vector mosquitoes in Cape Verde, demonstrating its inefficiency for the control of the malaria vector and the loss of susceptibility to the insecticide of the other potential vectors in the country. In turn, the study presents the biological larvicide Bti as an alternative, with 100% efficacy.

Why is it important?

The findings found in this study are relevant to the proper functioning of the national vector control program by warning of the loss of effectiveness of one of the main routine strategies used while pointing to an alternative, more effective, and respectful of the environment.


This publication reinforces the importance of local applied research to solve problems and improve public policies in the area of ​​vector control and vector-borne diseases in Cape Verde. In turn, it brings preliminary positive results on the biological larvicide Bti, which is pointed out as an alternative that, after being confirmed with other complementary studies, could be used as a vector control strategy in the country.
