Abstract: In this paper, the effect of three rice materials on the growth, development and fecundity of white-backed planthopper was studied based on the Two-sex life table technique. The results showed that compared with the insect-susceptible material ‘TN1’, the insect-resistant material ‘79-1163’ and ‘S1022’ significantly affected the development duration and adult life span of white-backed planthopper. ‘79-1163’ significantly prolonged the pre-adult stage, and ‘S1022’ and ‘79-1163’ significantly reduced the adult life span. The nymph survival rate, fecundity, intrinsic increase rate, finite increase rate, and net reproductive rate of white-backed planthopper fed on ‘79-1633’ were significantly lower than those of on ‘TN1’, also ‘S1022’. The white-backed planthopper fed on the three materials mostly developed into long-winged type. The sex ratio of white-backed planthopper fed on ‘TN1’ and ‘S1022’ were higher than 1, except for ‘79-116’. Both rice materials ‘79-1633’ and ‘S1022’ showed antibiotic resistance to white-backed planthopper, and ‘79-1633’ showed more obvious antibiotic resistance than ‘S1022’. The results are of great significance for the analysis of resistance mechanism to white back planthopper and discovery of resistance genes in rice.
