摘要
2009—2010年于河北省廊坊市对棉田绿盲蝽Apolygus lucorum(Meyer-Dür)的空间分布型及其抽样模型进行了研究。结果表明,绿盲蝽成虫空间分布型与其种群密度有关,当种群密度大于百株1.6头时呈随机分布,当小于百株1.6头时一般呈聚集分布;绿盲蝽若虫在不同种群密度下均呈聚集分布;绿盲蝽整个种群呈Possion分布。应用Iwao的抽样模型建立了棉田绿盲蝽的理论抽样数公式:N=(1.35/x珋)/D2。
We studied the spatial distribution of Apolygus lucorum (Meyer-Dtlr)in cotton fields in Langfang, Hebei Province in 2009 and 2010. The results show that the spatial distribution of adult A. lucorum usually fitted a uniform distribution when population density was higher than 1.6 individuals per 100 cotton plants, and changed to a clumped distribution if the density was lower than this. The spatial distribution of A. lucorum nymphs was clumped, whereas that of the population as a whole approximated the Possion distribution. The formula of the optimum theoretical sampling model constructed using Iwao' s method was N = ( 1.35/x)/D2.
