摘要
该文研究了黄板对茶园绿盲蝽种群动态及空间分布型的影响。在绿盲蝽高发期,黄板处理对绿盲蝽的发生量有着很好的控制作用,与对照处理差异显著;应用几种聚集度指标的计算公式和Iwao、Taylor的回归方程式,分析和测定结果表明在绿盲蝽高发期,黄板处理改变了绿盲蝽的空间分布型,为均匀分布,对照处理为聚集分布。
Yellow sticky traps has been used to control pests in tea garden. The effects of yellow sticky traps on green plant bug population dynamics and spatial distribution were studied in this paper. Population dynamics studies showed that yellow sticky traps had effective control effect on the amount of green plant bug in high-incidence season, which was significantly different from that of control. Several indicators of aggregation formula and Iwao, Taylor＇s regression equation were applied to analyze the spatial distribution pattern of green plant bugs treated with the yellow sticky traps and control. The results showed that yellow sticky traps changed the spatial distribution pattern of green plant bug to evenly distribution in high-incidence season, while the control was aggregatively distributed.
