Abstract
Ten plants of pesticidal value, suggested by a
group of organic farmers in Perambalur district of Tamil Nadu, were subjected
to laboratory bioassay to validate their anti- insect potency against Spodoptera frugiperda. Out of those ten plants, at 5% aqueous extract, Cleistanthus
collinus showed the maximum antifeedancy. The highest larval malformation
of 33.33% was observed at 5% aqueous extract of N. nucifera. The maximum
of 26.67% pupal malformation was recorded in W. tinctoria and M.
dubia. The highest adult deformity was noted in N. nucifera, E.
agallocha and M. dubia (33.33% each) extracts. After observation
taken on malformation, about 86.67% deformity were recorded at various stages
in N. nucifera and M. dubia, and exhibited the lowest
normal adult emergence of 13.33% was observed,
