Abstract—Terpenoid compounds in resistant rice varieties that acted as allelochemicals affecting feeding behavior of the brown planthoppers (BPHs) were extracted by solid phase microextraction (SPME) and analyzed by using gas chromatography-mass spectrometry (GC-MS). Comparative study of terpenoid profiles of susceptible Khao Dawk Mali 105 (KDML105), resistant Rathu Heenati (RH), and their isogenic lines (IL) IL162, IL302, and IL283, was performed. Six monoterpenoids which were (E)-citral, citronellal, (E)-geraniol, β-citronellol, citronellyl acetate and geranelyl acetate, were detected only in leaves of the resistant and their 3 isogenic line rices. Antibiosis, antixenosis and tolerance experiments suggested that the RH and its 3 isogenic line rices had higher level of antibiosis, antixenosis and tolerance against BPHs than KDML105. Moreover, spraying 6 standard monoterpenoids on susceptible Taichung Native 1 (TN1) rice could decrease feeding activity of BPHs.
