Description |
In the light of recent increased interest in
developing plant based secondary chemistry into
products suitable for integrated pest management,
the objective of the present study was to investigate
the bioactivity in Weld simulated conditions and structure–
activity relationship of some natural phenylpropenes
and their related analogues (1–6) against
Aphis craccivora. The activities of different compounds
varied depending on the substitution of the
functional groups and the side chain attached to the
aromatic ring of the phenylpropene. Dimethyleugenol
(5) showed maximum activity among all tested
phenylpropenes with LC50 values 880 and 2,047 ppm
against nymphs and adults respectively. Present study
showed that phenylpropenes appear to be promising
natural insecticides and may hold potential for identi-
fication of new lead structures against A. craccivora.
The activity of the most active phenylpropene (5) was
comparable with that of the chemical pesticide
(dimethoate)
