对新疆吐鲁番地区葡萄斑叶蝉在葡萄园葡萄上的发生规律及种群空间分布型进行了研究。结果表明,该蝉在吐鲁番地区1年发生4代,1代高峰在5月中旬,其余各代世代重叠。其空间分布和温度变化关系密切,在春季平均气温20~30℃之间,种群趋于分布在藤架的中、高部位,而随着夏季温度的升高,种群向中、低位较荫蔽的部位转移,并通过在遮蔽物下躲藏或在阴凉湿润的土壤表面停留降温等措施度过极端温度。采用Taylor幂法则、Iwao的m*-m回归分析法分析表明,吐鲁番地区葡萄斑叶蝉发生活动期为聚集分布,并且随种群密度的变化,呈现扩散-聚集-扩散-聚集-扩散-聚集的变化规律。
The occurrence regularity and spatial distribution pattern of grape leafhoppers on grapes in the Turpan region of Xinjiang Autonomous Region were studied. The results showed that the cicada occurred in Turpan region 1 year 4 generations, the first generation peak in mid-May, the remaining generations of overlapping generations. The spatial distribution was closely related to the temperature change. At the average temperature of 20 ~ 30 ℃ in spring, the population tended to distribute in middle and high parts of the rattan frame. However, with the increase of the summer temperature, the population was shaded to the middle and lower parts Site transfer, and through the shelter under shelter or stay cool in the cool wet soil surface temperature and other measures to spend extreme temperatures. Using Taylor’s law of power and Iwao’s m * -m regression analysis, it showed that the active period of the grape leafhopper in Turpan was aggregated distribution, and with the population density change, it showed the characteristics of diffusion-aggregation-diffusion-aggregation-diffusion- aggregation The law of change.
