【摘要】 本文通过五个不同温度的实验,编制成蚊生命表。说明:①成虫前期发育历期随温度的上升而缩短;卵的存活率是影响成虫前期存活率的主要因素;②各个实验温度的成蚊存活率随年龄的增长呈恒定的百分率下降,其存活率曲线都与SlobodkinⅢ型相似;③成蚊预期寿命与温度呈负相关,回归系数b值均有显著性(P<0.001);④不同温度的成蚊预期寿命,用生殖营养周期换算为生理龄期,更能说明寿命与流行病学的关系,并在五个实验温度中,25℃似乎更有利于登革热的传播。更多还原

【Abstract】 The life table of laboratory Aedes albopictus was constructed under various temperatures, from 20-30℃. The developmental duration of immature instars is decreased with Increase of temperature, and their survivoships are influenced chiefly by the survival rate of the egg stage. The decrease of adult survival rate is constant in related to age, similar to survival curve Slo-bodkin Ⅲ. The life expectation is corrlated to temperature in negative linear regression (P< 0.001). Basing on the duration of gonotrophic cycle in different temperatures, the life expectation was in terms of physiological age suggesting that 25C is favorable for transmitting dengue fever.更多还原
