Larvicidal activity of oils, fatty acids, and methyl esters from ripe and unripe fruit of Solanum lycocarpum (Solanaceae) against the vector Culex quinquefasciatus (Diptera: Culicidae)

Rev Soc Bras Med Trop. 2015 Sep-Oct;48(5):610-3. doi: 10.1590/0037-8682-0049-2015.

Abstract

Introduction: The larvicidal activity of oils, fatty acids, and methyl esters of Solanum lycocarpum fruit against Culex quinquefasciatus is unknown.

Methods: The larvicidal activity of samples of ripe and unripe fruit from S. lycocarpum was evaluated against third and fourth instar larvae of C. quinquefasciatus .

Results: The oils, fatty acids, and methyl esters of S. lycocarpum showed the greatest larvicidal effect (57.1-95.0%) at a concentration of 100mg/L (LC 50values between 0.70 and 27.54mg/L).

Conclusions: Solanum lycocarpum fruit may be a good source of new natural products with larvicidal activity.
