Abstract: In the present study, we investigated the systematically induced production of defenserelated compounds, including DIMBOA, total phenol, trypsin inhibitors (TI) and chymotrypsin inhibitor (CI), by Tetranychus cinnabarinus infestation in Zea mays. The first leaves of two corn inbred line seedlings, the mitetolerant line ‘H1014168’ and the mitesensitive line ‘H1014591’, were sucked by T. cinnabarinus adult female for seven days, and then the contents of DIMBOA, total phenol, TI and CI were measured in the second leaf and in the roots, respectively. Results showed that as compared to the unsucked control, all contents of DIMBOA, total phenol, TI and CI induced by T. cinnabarinus sucking were significantly higher in the second leaf of both inbred lines as well as in the roots of the mitetolerant ‘H1014168’. However, in the roots of ‘H1014591’, these defense compounds had different trends, where there was a higher induction of TI and a lower level of total phenol than that of the healthy control, while had almost no difference in DIMBOA and CI. These findings suggested that the infestation of T. cinnabarinus could systematically induce accumulation of defenserelated compounds, and this effect was stronger in the mitetolerant inbred line than in the mitesensitive inbred line.
