在重庆永川的自然生态茶园、有机茶园、无公害茶园中,利用黄板诱集和常规方法监测茶假眼小绿叶蝉的田间年发生消长动态。试验结果显示,两种方法监测该虫的发生趋势动态基本一致,相关系数达极显著水平;在越冬期和早春时节,黄板诱集比常规调查方法能更早和更直观地监测叶蝉的越冬虫口和残存虫量;在第1高峰始期预测中,常规方法以假眼小绿叶蝉田间百叶虫量超过10头作为入峰的临界值,对应黄板监测的临界虫口量0.124头/cm2。
In the natural ecological tea garden, organic tea garden and pollution-free tea garden in Yongchuan, Chongqing, yellow-leaf trapping and conventional methods were used to monitor the dynamics of annual growth of the tea leafhopper. The results showed that the trend of the two methods was basically the same, and the correlation coefficient reached the extremely significant level. During the wintering and early spring seasons, the yellow board trapping could monitor leafhopper earlier and more intuitively than the routine survey Overwintering insect population and remaining insects; in the first peak of the initial prediction, the conventional method of false green leafhopper field flamingo more than 10 as the threshold value of the peak, corresponding to the yellow board monitoring of the critical population of 0.124 head / cm2.
