Abstract: To illustrate the spatial pattern of Laelaps echidninus and Laelaps nuttalli (two important species of gamasid mites in the indoor and outdoor cultivated habitats in western Yunnan, China) among the individuals (point plots) of their dominant rodential hosts, Rattus flavipectus, Rattus norvegicus and Rattus nitidus, Iwao's regression model and the significance test of random deviation for the model were used.In the light of Iwao's model, tworegressionequations, M※= 4.9985 + 3.0248M(α= 4.9985, β = 3.0428,r= 0.6979, P<0.05) for Laeleps echidninus and M※= 2.9258 + 4.8130M (α= 2.9258, β = 4.8130, r =0.7767, P< 0.01) for Laeleps nuttalli were established.Both α and β in the equations were considerably higher than 0 or 1, the border values for determining spatial patterns of populations.The F values were 13.3256 (P< 0.01) for Lateleos echidninus and 10.1000 (P<0.01) for Laeleps nuttalli respectively in the significance test of random.The results proved that the spatial patterns of Laeleps echidninus and Laelaps nuttalli among the different individuals (poit plots) of their dominant hosts be aggregate distribution.
摘要: 目的:分析两种革螨的空间分布型。方法:用Iwao模型,对云南西部毒厉螨及纳氏厉螨两种主要革螨在其主要寄生宿主黄胸鼠、褐家鼠及大足鼠个体样方间的空间分布型进行了测定,并对其进行了随机分布偏离度检验。结果:在Iwao模型所建的回归方程中,毒厉螨(M※=4.9985+3.0428M,α=4.9985,β=3.0428,r=0.6979,p<0.05)及纳氏厉螨(M※=2.9258+4.8130M,α=2.9258,β=4.8130,r=0.7767,P<0.01)的α、β值均高于判定界线的0或1,经随机偏离度检验,P<0.01。结论:这两种革螨在其所寄生的各主要宿主个体样方间里聚集型分布。
