摘要
仿生胶已成为一项防控病虫害的新技术,本文研究了仿生胶对枸杞瘿螨种群动态及空间分布型的影响。种群动态研究表明:仿生胶处理对瘿螨的发生量有着很好的控制作用,与药剂处理和对照处理差异显著;应用几种聚集度指标的计算公式和Iwao、Taylor的回归方程式,分析和测定了3种处理瘿螨的空间分布格局,结果表明在采果期仿生胶处理阶段性地改变了瘿螨的空间分布型,为聚集分布,药剂处理和对照处理均为均匀分布。
Bionic glue has become a new technology for control of diseases,insects and pests.The effects of bionic glue on wolfberry gall mite population dynamics and spatial distribution was studied in this paper.Population dynamics studies showed that bionic plastic had good control effect on the amount of gall mite,which significantly different from that of pesticide treatment and control.Several indicators of aggregation formula and Iwao,Taylor＇s regression equation were applied to analyze the spatial distribution pattern of gall mites treated with bionic glue,pesticide and control.The results show that bionic plastic changed the spatial distribution pattern of gall mites to aggregated distribution in the fruit picking period,while pesticide treatment and control are evenly distributed.
