摘要

The brown plant hopper (BPH) is an economically important insect pest of rice. Herbivore induced plant volatiles (HIPVs) have greater role in plant defense as repellents or feeding inhibitors or cues for natural enemies. In this study, volatiles induced after BPH infestation from susceptible (TN1) and resistant (Ptb33) rice varieties were identified using Gas Chromatography Mass Spectrophotometer (GCMS) and NIST MS 2 library. Ptb33 infested samples had defensive volatiles like stigmasterol, p-sitosterol, hexadecenoic acid, benzothiazole, phytol, nonanal with highest peak area %. In infested samples of TNI, only a few defense related volatiles like a-copaene were found. Eleven and sixteen overlapping volatiles were identified in infested and uninfested samples of TNI and Ptb33, respectively. In addition to the host plant resistance in Ptb33 to BPH, induced volatiles provide indirect defense.
