Evaluation of insecticidal properties of sage, Salvia officinalis leaves against Aphis fabae Scopoli, 1763 (Homoptera: Aphididae)

Active and non-polluting natural substances are a promising alternative solution for the protection of crops. This is the context of this study, which aims to evaluate the insecticidal potential of sage in order to control the black bean aphid. The aqueous solution of faba bean, Salvia officinalis was tested at different doses (10, 20, 30, 40 and 50%) on batches consisting of different larval stages of A. fabae. The results obtained indicate that this plant has a toxic effect on the aphidian populations with a high mortality of 98.54% at a dose of 40%. The highest mortality is noted 9 days after treatment. The insecticidal effect of sage seems to depend on the dose and time.
