The intrinsic rate of increase (r) of the SBPH was the highest (0.1067 d(-1)) on cultivar SD15, which was similar to the rate on SD14 (0.1029 d(-1)), but was significantly higher than that occurring on ZXN (0.0897 d(-1)) and SD13 (0.0802 d(-1)). The differences of the finite rate of increase (lambda) on the four rice cultivars were consistent with the r values. Population projection predicted an explosive population growth of the SBPH occurring in a relatively short time when reared on SD14 and SD15. These findings demonstrated that the SBPH can successfully survive on the four rice cultivars, although there were varying host adaptabilities.eninfo:eu-repo/semantics/openAccessAge-StageLaodelphax-StriatellusHemiptera Delphacidae2-SexResistanceHomopteraDipteraHostTemperaturePerformanceArticle710.1038/srep42399282055222-s2.0-85012285139Q1WOS:000394328300001Q1
