Different susceptibilities of Aedes aegypti and Aedes albopictus larvae to plant-derived products

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

INTRODUCTION:

Aedes aegypti and Aedes albopictus are important vectors that transmit arboviruses to human populations.

METHODS:

Natural products were obtained and tested against larvae collected from the field in Fortaleza, capital of Ceará state.

RESULTS:

The essential oils of Syzygium aromaticum (Ae. aegypti LC₅₀ = 32.7 ppm and Ae. albopictus LC₅₀ = 138.1 ppm) and Croton nepetaefolius (Ae. aegypti LC₅₀ = 81.7 ppm and Ae. albopictus LC₅₀ = 76.1 ppm) showed the most intense larvicidal activity.

CONCLUSIONS:

The essential oils and methyl esters showed greater larvicidal activity than did the ethanol extracts.

Keywords:
Larvicidal activity; Aedes; Botanical products; Mosquito-borne virus
