| Abstract: | Experimental population life tables of imidacloprid-resistant and susceptible BPH populations feeding on two rice varieties(TN1,IR36) were compiled and their population number tendency index(PNTI) and fitness determined.The results show that the PNTI of resistant and susceptible BPH feeding on the susceptible rice variety TN1 were 55.33 and 105.57,respectively,and that the relative fitness of resistant compared to susceptible BPH was 0.5241.However,on the pest-resistant rice variety IR36,the PNTI of resista... |
