气象因素对白纹伊蚊生态学变化的影响
Effects of meteorological factors on the ecological changes of Aedes albopictus
【摘要】 白纹伊蚊是一种重要的媒介昆虫,可传播登革热、寨卡病毒病和基孔肯雅热等疾病。近年来,其在中国的分布范围显著扩展,与全球气候变化密切相关。本文综述了气象因素(温度、降水、相对湿度和光周期)对白纹伊蚊生态学变化的影响。温度是影响白纹伊蚊种群动态和病毒传播效能的关键因素,白纹伊蚊卵的孵化和发育的最适温度为20~30℃,但温度超过30℃后幼虫至成虫的发育速度会降低,极端高温(≥40℃)对白纹伊蚊生存和繁殖具有严重影响,卵无法孵化,幼虫及成蚊发育停滞。降水和相对湿度对白纹伊蚊的繁殖和存活也有显著影响,适宜的降水和高湿度环境有利于其种群增长。光周期则通过诱导滞育影响白纹伊蚊的季节性动态。气象变化如温度升高和降水模式改变可能进一步扩大白纹伊蚊的适生区,增加疾病传播风险。温度、相对湿度和光周期的交互作用可以影响白纹伊蚊的生长、发育和繁殖。了解白纹伊蚊对气象变化的响应对于制定有效的防控策略至关重要。
【Abstract】 Aedes albopictus is an important vector that can transmit diseases such as dengue fever, Zika virus disease and chikungunya fever. In recent years, its distribution in China has expanded significantly, closely linked to global climate change. This paper reviews the impact of meteorological factors(temperature, precipitation, relative humidity and photoperiod) on the ecological changes of Ae. albopictus. Temperature is a key factor affecting the population dynamics and viral transmission efficiency of Ae. albopictus. The optimal temperatures of egg hatching and development are between 20 ℃ and 30 ℃.However, when the temperature exceeds 30 ℃, the development rate from larvae to adults will decrease. Extreme temperatures(≥40 ℃) have a serious impact on the survival and reproduction of Ae. albopictus, preventing egg hatching and causing developmental stagnation in larvae and adults. Precipitation and relative humidity substantially influence Ae. albopictus reproduction and survival, with favorable conditions driving population growth. Photoperiod regulates seasonal dynamics by inducing diapause. Meteorological change, such as increased temperatures and altered precipitation patterns, may expand the habitat of Ae. albopictus and increase the risk of disease transmission. The interaction of temperature, relative humidity and photoperiod significantly affects the growth, development and reproduction of Ae. albopictus. Understanding the response of Ae. albopictus to meteorological changes is essential for developing effective control strategies.
