摘　　要：本文利用两性生命表技术开展了3种水稻材料对白背飞虱生长发育及繁殖的影响研究.结果表明,相较于感虫材料“TN1”,抗虫材料“79-1163”和“S1022”显著影响白背飞虱发育历期和成虫寿命,其中,“79-1163”显著延长白背飞虱成虫前期,“S1022”和“79-1163”显著降低成虫寿命.取食79-1633的白背飞虱若虫存活率、繁殖值、内禀增长率、周限增长率、净增殖率等均显著低于“TN1”,也低于“S1022”. 3种材料饲喂的白背飞虱多发育为长翅型.除“79-1163”饲喂的白背飞虱性比小于1外,其余两种材料均大于1.本研究表明,水稻材料“79-1633”与“S1022”对白背飞虱均表现出抗生性,“79-1633”抗生性较“S1022”更明显,研究结果为解析白背飞虱的抗性机理、挖掘抗性基因具有重要意义.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.
