The effect of temperature on the development and fecundity of Sancassania polyphyllae fed on tissues of Polyphylla fullo larvae was studied at 15, 20, 25, 30, and 35 ± 1°C and 65 ± 10% RH in a dark incubator. Mean developmental period of immature stages decreased significantly with increasing temperatures from 15 to 30°C. Developmental periods at 30-35°C were not significantly different. The estimated lower developmental thresholds of the various immature stages ranged between 10.1 and 11.5°C. The thermal constant for the egg-to-female adult was 93.5 degree-days. The pre-oviposition, oviposition, and post-oviposition periods and female longevity were significantly longer at 15°C than at higher temperatures. Mean total and daily fecundity were the highest at 25°C, which were significantly different from those obtained at 15, 20 and 30°C. The net reproductive rate (R (0)) was the highest at 25°C (588.3 ♀/♀). The longest mean generation time (T (0)) occurred at 15°C (36 days) and the shortest occurred at 30°C (9.2 days). The highest intrinsic rate of increase (r (m)) for S. polyphyllae was observed at 25 (0.61 ♀/♀/day) and 30°C (0.62 ♀/♀/day).
在黑暗培养箱中，相对湿度为 65±10%，温度分别为 15、20、25、30 和 35±1°C 的条件下，研究了温度对取食 Polyphylla fullo 幼虫组织的 Sancassania polyphyllae 的发育和繁殖的影响。从 15 到 30°C，未成熟阶段的平均发育时间随着温度的升高而显著降低。30-35°C 之间的发育时间没有显著差异。各未成熟阶段的估计下限发育温度在 10.1 到 11.5°C 之间。从卵到雌成虫的热常数为 93.5 度天。15°C 时，预产卵、产卵和产卵后时期以及雌虫寿命明显长于高温时。25°C 时总产卵量和日产卵量最高，与 15、20 和 30°C 时获得的产卵量有显著差异。净生殖率（R（0））在 25°C 时最高（588.3♀/♀）。平均世代时间（T（0））最长发生在 15°C（36 天），最短发生在 30°C（9.2 天）。S. polyphyllae 的最高内禀增长率（r（m））出现在 25（0.61♀/♀/天）和 30°C（0.62♀/♀/天）。
