摘要
为明确茶小绿叶蝉在豫南地区的发生规律及温度对种群数量的影响,通过茶园悬挂黄板诱捕及室内温度梯度处理相结合的方法,研究温度在其发生中的作用。结果表明,成虫在该地区每年均有2个高峰期,分别出现在6月下旬—8月上旬和9月上旬—11月下旬。室内研究表明,极端温度胁迫下,短期内即可造成茶小绿叶蝉叶蝉成虫大量死亡。因此,适宜茶小绿叶蝉发生温度为16.79-22.78℃,平均温度低于10℃或高于29℃,则虫口数量急剧下降。
In order to study the occurrence regularity and the influence of temperature on the populationdynamics of Empoasca onukii, yellow sticky traps were hung in tea plantation to trap Empoasca onukii, andtemperature gradients were set up in the laboratory to determine the survival rate. The results showed that thepopulation of adults had two peaks every year in this region, appearing from late June to early August and fromearly September to late November. Laboratory research showed that a mass mortality of Empoasca onukii appeared under extreme temperature stress in the short term. So the suitable temperature for Empoasca onukii was 16.79-22.78℃. A massive mortality would appear when the average temperature was below 10℃ or above 29℃.
