At different observation intervals of 1, 5, and 10 days during a trial period of 30 days, the mortality rates of were 100, 95, and 55%, and the fecundity rates were 0.55, 8.45, and 19.35 eggs/female, respectively. At temperatures of 18, 21, 24, and 27 °C, the development time of the immature stage of was significantly shortened with increasing temperature. Furthermore, the lower developmental threshold () and thermal summation () of the immature stage were 8.91 °C and 485.44 degree-days, respectively. The greatest longevity of female and male adults reached 115.77 and 26.50 days, respectively, at 18 °C. The highest fecundity was 29.00 eggs/female at 24 °C. The population parameters of were analyzed on the basis of the age-stage, two-sex life table theory. According to the data, the parameters were significantly affected by temperature. The highest net reproductive rate () was 13.32 eggs/individual at 24 °C. The highest intrinsic rate of increase () and finite rate of increase () were calculated as 0.0401 and 1.0409 day, respectively, at a temperature of 27 °C. The shortest mean generation time () was 51.34 days at 27 °C. Overall, we provide a discussion on comprehensive biological information regarding , thus providing basic knowledge for further research on this pest.
在30天的试验期内，分别在1、5和10天的不同观察间隔下，[具体物种未给出]的死亡率分别为100%、95%和55%，而繁殖率分别为0.55、8.45和19.35枚卵/雌虫。在18、21、24和27℃的温度下，[具体物种未给出]未成熟阶段的发育时间随温度升高而显著缩短。此外，未成熟阶段的较低发育阈值（）和热常数（）分别为8.91℃和485.44日度。在18℃时，雌虫和雄虫成虫的最长寿命分别达到115.77天和26.50天。在24℃时，最高繁殖力为29.00枚卵/雌虫。基于年龄-阶段两性生命表理论分析了[具体物种未给出]的种群参数。根据数据，这些参数受到温度的显著影响。在24℃时，最高净繁殖率（）为13.32枚卵/个体。在27℃的温度下，最高内禀增长率（）和有限增长率（）分别计算为0.0401和1.0409天⁻¹。最短平均世代时间（）在27℃时为51.34天。总体而言，我们提供了关于[具体物种未给出]综合生物学信息的讨论，从而为对该害虫的进一步研究提供基础知识。
