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 green leafhopper growth and development and temperature are closely related. In this study, the developmental onset temperature (C), effective accumulated temperature constant (K) and developmental mathematic model (y) of each developmental stage were defined as: C = 9.30 ± 1.84 (℃), K = 121.03 ± 13.90 (day), y = 9.30 + 121.03x; nymph period C = 10.31 ± 3.15 (° C), K = 174.41 ± 36.03 (day), y = 10. 31 + 174.41x; whole generation C = 10.82 ± 1.16 (° C), K = 291.07 ± 21.26 (day), y = 10.82 + 291.07x. Proved by projections, and the actual occurrence of generations is basically the same number. In view of the serious overlap of the growing season generations, the prevention and treatment should be overwhelming winter medicine to kill overwintering adults in early spring before spawning; growth season combined with picking the same time pest control, it is appropriate to grasp the young nymphs in full bloom and timely application of pesticide control.
