ABSTRACT
Abstract

INTRODUCTION:

Bioprospection of plant products is used to discover new insecticides.

METHODS:

The larvicidal activity of ethanolic extract and triterpene (tingenone B) from the bark of Maytenus guianensis and their effect on pupation and emergence were evaluated against Aedes aegypti.

RESULTS:

Crude extract LC50 was 11.3 ppm and caused ejection of the larvae intestine; tingenone B LC50 was 14.8 ppm. Pupation was reduced by 20% and 10%, respectively; however, the emergence was not affected.

CONCLUSIONS:

The crude bark extract exhibited a higher larvicidal effect against the vector.
