Potential use of Piper nigrum ethanol extract against pyrethroid-resistant Aedes aegypti larvae

Utilização em potencial do extrato alcoólico de Piper nigrum como larvicida em Aedes aegypti resistente a piretróides

Authorship SCIMAGO INSTITUTIONS RANKINGS

Fractionation of Piper nigrum ethanol extract, biomonitored by assays on pyrethroid-resistant Aedes aegypti larvae yielded isolation of the larvicidal amides piperolein-A and piperine. Comparing LC50 values, the ethanol extract (0. 98 ppm) was the most toxic, followed by piperolein-A (1. 46ppm) and piperine (1. 53ppm).
