通过1960—1976年的研究,基本探明茶小绿叶蝉发生发展规律与环境条件的关系,提出了一套包括农业措施和合理用药的综合防治措施。冬春气温的高低和低温期的长短,是虫口消长的主导因子,冬、春气温高则为早发多发年份,夏茶、秋茶采摘期间分别形成一个高峰(双峰型)。冬春气温低且持续时间长,则为迟发少发年份,仅在秋茶及其后期形成一个高峰(单峰型);夏季长期高温干旱是虫口数量下降的原因;在温度适宜(22—26℃)季节,少雨是
Through the research from 1960 to 1976, the basic research on the relationship between the occurrence and development of the green leafhopper and the environmental conditions was made, and a set of comprehensive prevention and control measures including agricultural measures and rational drug use was put forward. The temperature of winter and spring and the length of the low temperature period are the dominant factors in the growth and decline of insects. The high temperature in winter and spring is the year of frequent occurrence of early onset and the peak (bimodal pattern) is formed respectively in the summer tea and autumn tea picking. The low temperature and long duration of winter and spring, the late onset and the late onset, only formed a peak in autumn tea and its later stage (unimodal type). The long-term high temperature and drought in summer was the reason of population decline. 26 ℃) season, less rain is
