方形黄鼠蚤松江亚种生存温区划分

Division of temperature ranges divided by survival length and mortality of Citellophilus tesquorum sungaris

摘要

摘要:
目的探讨方形黄鼠蚤松江亚种在游离状态下对温度变化的生命反应, 划分方形黄鼠蚤的生存温区。
方法观察方形黄鼠蚤松江亚种在不同温度下的存活时间, 测定其半数致死高温(TD₅₀)值, 根据存活时间和死亡率划分生存温区。
结果方形黄鼠蚤松江亚种半数致死高温雌性为40.81℃, 雄性为41.03℃; 致死高温区在42℃以上; 亚致死高温区在37.5~42℃之间; 适宜温区在2~35℃, 15~27.5℃为其最适温度范围, 20~25℃是其最适发育温度; 亚致死低温区在-2~-10℃; 致死低温区在-10℃以下。
结论温度是对方形黄鼠蚤松江亚种生存影响最大的气候因子, 游离状态下其生存温区与其他昆虫无明显区别。

Abstract:
Objective To study the effects of temperature on the flea(Citellophilus tesquorum sungaris)under the condition free of host.
Methods Different survival length was observed when the fleas were in different temperature.TD₅₀ of the flea was tested, and different temperature range was divided based on the survival length and the mortality of the fleas.
Results The TD₅₀ for the female fleas was 40.81℃, and for the male fleas was 41.03℃; lethal high temper ature was above 42℃; sublethal high temperature rnage was between 37.5℃ and 42℃; the suitable temperature range was between 2℃ and 35℃, w hile 15℃ to 27.5℃ was the optimum temperature range; sublethal low temperature range was between-2℃ and 10℃; lethal low temperature range was below -10℃.
Conclusion Temperature is the biggest climate factor for the effect on the citellophilus tesquorum sungaris, its temperature range of survival has no obviously differences with other insects under the condition free of host.
