Larvicidal effect of pepper plants on Aedes aegypti (L.) (Diptera: Culicidae)
Journal of Vector Ecology
Ethanolic extracts derived from three species of the Piperaceae (pepper) family, Piper longum L., P. ribesoides Wall., and P. sarmentosum Roxb. ex Hunt., were evaluated for efficacy against early 4 th instar larvae of Aedes aegypti mosquitoes using larvicidal bioassays. The highest larvicidal efficacy was established from P. longum, followed by P. sarmentosum and P. ribesoides, with LC 50 values of 2.23, 4.06, and 8.13 ppm, respectively.
