摘要
茶小绿叶蝉生长发育与温度关系密切。本研究明确各发育阶段的发育起点温度（Ｃ）、有效积温常数（Ｋ）和发育数学模式（ｙ）分别为：卵期Ｃ＝９．３０±１．８４（℃），Ｋ＝１２１．０３±１３．９０（日度），ｙ＝９．３０＋１２１．０３ｘ；若虫期Ｃ＝１０．３１±３．１５（℃），Ｋ＝１７４．４１±３６．０３（日度），ｙ＝１０．３１＋１７４．４１ｘ；整个世代Ｃ＝１０．８２±１．１６（℃），Ｋ＝２９１．０７±２１．２６（日度），ｙ＝１０．８２＋２９１．０７ｘ。经推算验证，与各地实际发生世代数基本一致。鉴于生长季世代重叠严重，防治上宜药杀越冬成虫于早春产卵之前；生长季结合采摘同时治虫，则宜掌握幼龄若虫盛期及时施药控制。
Tea jassid (Empoasca vitis Gothe) is one of the most dominant pest insect in the tea gardens in China.Relationship between temperature and development of tea jassid was investigated and it was found that the threshold temperature for development (C) were 9 30±1 84 (℃),10 31±3 15 (℃) and 10 82±1 16 (℃),respectively,and the effective thermal constant (K) were 121 03±13 90 (degree days),174 41±36 03 (degree days) and 291 07±21 26 (degree days),respectively in egg stage,nymph stage and whole generation.Based on the threshold temperature for the development and effective thermal constant observed,the dynamics of generation of the pest in different regions were forecasted which agreed with the actual development of generation.
