我国茶园总面积为1615.9万亩,有山地、丘陵和平坦地三类茶园组成,分布在不同的海拔。国营茶场栽培管理好,施药水平高,茶园产量高,害虫种类少,优势种突出;社、队所属的茶园,管理粗放,用药水平低,甚至常年不用药,茶园产量低,害虫种类多,优势种不明显,以体形大的鳞翅目害虫为主。茶园害虫的优势种群,在五十年代前,因生态环境稳定,很少发生变化。五十年代起,由于科学技术的迅速发展,茶园受到了外界人为因素的剧烈干扰,改变了茶园的生态环境,加速了害虫种群的演替。五十年代有机氯农药的使用,诱使蚧类上升为重要的害虫种群,而
The total area of tea plantations in China is 16,159 mu, with three types of tea gardens, including hills, hills and flat terraces, distributed at different elevations. The management of state-run tea farms is good, the level of pesticide application is high, the output of tea plantations is high, the pest species are few, and the dominant species are prominent. The tea plantations belonging to the clubs and teams have extensive management, low drug levels and even no perennial use. The dominant species are not obvious, with large lepidopteran pests mainly. The dominant species of tea plantation pests rarely changed before the 1950s due to the stable ecological environment. Since the 1950s, due to the rapid development of science and technology, the tea plantation has been violently disturbed by human factors, changing the ecological environment of the tea plantation and accelerating the succession of pest populations. The use of organochlorine pesticides in the 1950s induced the scale to rise as an important pest population
