Evaluation of the aphicidal activity of Salvia microphylla (Lamiaceae) aqueous extracts against Aphis pomi (Aphididae)

Abstract

The aphid Aphis pomi represents an important pest of apples. The use of botanical extracts may be a safe and effective way to control this pest. In this context, we studied the aphicidal and repellent effects of aqueous extracts of Salvia microphylla against A. pomi. Five concentrations were tested on two main aphid parameters: mortality rate and percentage of repellency. The results showed that concentrations of 10% recorded the highest mortality rate (73.33%) and percentage of repellency (62.59%). After further field investigations, the use of S. microphylla may constitute a component of the integrated management of aphids.
