Chemical constituents of Piper betle extract were studied to identify the active component that could be responsible for any attractant property on the Oriental Corn Borer, Ostrinia salentialis. Extraction process was conducted on locally collected Piper betle leaves using petroleum ether and methanol. Essential oil was also extracted using hydrodistillation and analysed by GC-MS. Two major components isolated from the petroleum ether extract were identified as chavibetol [2-methoxy-5-(2-propenyl)phenol] and β-sitosterol while one major component isolated from methanol extract was identified as allylpyrocatechol [4-(2-propenyl)- 1,2-benzenediol]. All the three components were identified based on their GC-MS, ¹³C and ¹H NMR data and also by comparison with literature. Field evaluation using traps containing petroleum ether extract, methanol extract and essential oil of Piper betle were conducted in a cornfield and adult moths of Ostrinia salentialis were not detected.
