Abstract

Abstract The larvicidal activity of 18 phenylpropanoids, 1–18, including phenylpropenoate, phenylpropenal, phenylpropene, and their semisynthetic analogues, were evaluated against the tobacco armyworm, Spodoptera litura (Fab.), to identify promising structures with insecticidal activity. Amongst various phenylpropanoids, isosafrole, a phenylpropene, showed the best activity, with an LC 50 value of 0.6 μg/leaf cm 2, followed by its ...
