摘  要  【目的】 明确温度对中国梨木虱Psylla chinensis生长发育和繁殖的影响。【方法】 室内条件下, 16、20、24、28、32和36 ºC分别测定中国梨木虱各阶段发育历期、产卵量和存活率等，制定其年龄-龄期两性生命表，利用两性生命表计算其存活率、繁殖力、寿命期望、繁殖值和种群参数。【结果】 16-24 ℃，中国梨木虱随温度升高，其生长速度加快、发育历期缩短；24-32 ℃其发育历期变化不显著；36 ℃条件下不能完成整个生长发育。24 ℃时产卵量最高，为281.50粒/雌。16-24 ℃，中国梨木虱的年龄特征存活率、种群特定年龄净繁殖力、平均贡献度均随温度升高而增加，24-32 ℃，均随温度升高而下降。24 ℃处理的内禀增长率、周限增长率和净增值率均最高，28 ℃处理的平均世代周期最短。【结论】 结果表明中国梨木虱生长发育和繁殖适宜温度为24-28 ℃。

Abstract  [Aim]  To determine the influence of temperature on the growth, development, and fecundity of Psylla chinensis. [Methods]  In a controlled laboratory environment, the developmental period, oviposition rate, and survival rate of P. chinensis were measured at 16, 20, 24, 28, 32 and 36 ℃. An age-stage two-sex life table was constructed and used to determine the survival rate, fecundity, life expectancy, reproduction value, and population parameters of P. chinensis. [Results]  Between 16-24 ℃, the growth rate of P. chinensis increased, whereas the developmental period decreased with increasing temperature. In contrast, temperatures between 24-32 ℃ had no significant effect on the developmental period. At 36 ℃, the development of P. chinensis was inhibited. The highest number of eggs were produced at 24 ℃ with 281.50 eggs per female. Between 16-24 ℃, the age-stage survival rate, population age-stage specific net reproductive rate, and the reproduction value increased with increasing temperature. However, they decreased as temperatures increase between 24-32 ℃. At 24 ℃, the intrinsic rate, net reproduction rate, and finite rate peaked, while the mean generation time reached a minimum value at 28 ℃. [Conclusion]  Based on the findings of this study, the optimal temperature range for the growth and development of P. chinensis is 24-28 ℃.
