Abstract:
The sweet flag Acoruscalamus L (vernacular: Bach) is a perennial herb belonging to the family Araceae. The main constituents of Acoruscalamus L, is β-asarone.β-Asaroneexhibits a broad range of biological activities. It is an insect growth regulator, we observed the effect of different concentrations (2, 4, 6, 8 and 10 μg / μl doses) of β-Asarone on the growth and development of Corcyra cephalonica, in our observations various morphological abnormalities like deformation and degeneration were observed in the larval and pupal stages. The untreated Corcyra cephalonica showed normal in the developmental stages with the larval instar stages and henceforth developimg into pupa without any deformities. However β-Asarone affected larval instars showed disrupted structures of the cuticle like tanning of cuticle and abnormal larvae over-aged larva with either complete or partial damage of pupa. The results demonstrated that β-Asarone causes rapid cessation of growth due to disruption of larval structure and inhibition of growth following topical treatment on 4th 5th instar and pupae of Corcyra cephalonica.
