Effects of transgenic Bt rice on non-target pests following pesticides applications play an important role in evaluating the ecological safety of transgenic rice. Changes of the life history parameters of laboratory population of Nilaparvata lugens feeding on transgenic Bt rice T2A-1 and its parental line cv. MH63 as the control, and the contents of oxalic acid and soluble sugar following three pesticides (triazophos, jinggangmycin and chlorantraniliprole) treatments were investigated in this

Results showed that the population parameters of N. lugens and the physiological and biochemical parameters of rice did not differ significantly between T2A-1 and MH63 without pesticide application.. But, the ER (emergence rate), the NN (nymphal number of next generation), and the IP (index of population trend) on T2A-1 treated with 10 ppm of triazophos were significantly higher than those on MH63, respectively, while the HB (hatchability) on T2A-1 treated with the three pesticides were lower obviously than those on MH 63 (Table 1-3) . Furthermore, the content of oxalic acid in MH63 treated with 20 ppm triazophos and, 40 and 80 ppm chlorantraniliprole was significantly higher than that in T2A-1, while the content of soluble sugar in T2A-1 treated with 400 ppm jinggangmycin was significantly higher than that in MH63, The results above indicated that triazophos in a low dose could cause a more favor of T2A-1 to population growth of N. lugens compared with MH 63. . 2003.
