The Influence of Temperature and Humidity on the Population Dynamics of Small Green Leafhopper at Tea Garden
-
摘要: 探讨茶园假眼小绿叶蝉的成虫、若虫及茶梢内着卵量的种群动态,以及温湿度对茶园中叶蝉种群数量的影响。结果表明,①成虫、若虫及梢内着卵量均有2个高峰期,分别出现在5月中旬至6月中旬和9月下旬至10月中旬,且成虫、若虫和卵三者都呈显著的正相关。②假眼小绿叶蝉的成虫、若虫虫口数量受田间气候条件影响较大,温度对假眼小绿叶蝉的影响最大,茶梢内假眼小绿叶蝉的着卵量与温度关系很密切,气温高于28℃或者低于20℃都不适宜小绿叶蝉产卵繁殖。③对温度和田间假眼小绿叶蝉成、若虫种群数量及梢内着卵量进行统计分析,结果表明,温度与假眼小绿叶蝉的成、若虫虫口数量、茶梢内着卵量呈现Yield Density模型变化规律。

Abstract: The paper discusses the population dynamics of the adult, nymph and egg density of small green leafhopper (SGL), the influence of temperature and humidity on the population dynamics of the SGL at the tea garden of Fujian Agriculture & Forestry University, Jinshan, Fuzhou, Fujian, 2007. The results showed:①The population dynamics of the SGL had two peaks, a significant positive correlation was shown among the population dynamics of the egg, nymph and adult of the SGL.②The population dynamics of the adult, nymph and egg density of the SGL was significantly affected by the temperature during the occurrence. While the average temperature above 28℃and lower 20℃ condition, the population dynamics of the SGL were declined rapidly.③The temperature for the dynamics of the adult, nymph population and egg density of the SGL were coincided with the Yield Density model.-
