| Summary: | Both seed and root extracts of the medicinal plant, Ashwagandha, Withania somnifera exhibit
insect growth regulatory activity against the polyphagous pest, Pericallia ricini. Topical
administration of W. somnifera seed and root extracts to last instar larvae of P. ricini
disrupted moulting and metamorphosis, leading to a number of developmental abnormalities
such as delay in larval-pupal and pupal-adult ecdysis, formation of larval-pupal, pupal-
-adult and larval-pupal-adult mosaics/chimeras, ecdysial failure, suppression of pupation
and adult emergence and formation of abnormal pupae and adultoids. The treatment with
seed extracts was more severe than that of root extracts as it completely suppressed the
pupation and adult emergence. The results clearly suggest that the medicinal plant, W. somnifera
acts as a potential insect growth regulatory (IGR) disrupting the moulting and metamorphosis
as a consequence of interference with the endocrine system. |
