Impact of soil spatial variability on spatial distribution pattern of Locusta migratoria manilensis eggpods in Nandagang reservoir,Hebei,were studied by means of geostatistical analysis and GIS techniques.Results show that soil properties,such as salt content,water content at 5 cm depth,organic matter and pH,displayed significant spatial heterogeneity,but the first two demonstrated close spatial correlation and the last two moderate spatial correlation,and the distribut ion of locust egg pods,significant spatial auto correction.Locust eggpods were mainly distributed in the central and eastern parts of the study zone,where the soil was low in salinity (<9%) and moderate in water content (10.1%~29.9%),but they were rarely found in the western and northern parts,where the soil was high in water content (>30%) and in salinity (>3%).The find ings indicate that the spatial distribution pattern of locust eggpods is mainly related to spatial variability of the soil in the study area.
