Batocera lineolata is an important wood\\borer pest in China, mainly attacking the trunk of ash trees Fraxinus velutina, a predominant forest species in the Yellow River Delta, causing severe damage. In the present study, the spatial distribution patterns of eggs, larvae, and adults or pupae of the B. lineolata population were analyzed using geostatistical methods. The egg niche, frass hole, and emergence hole at four ash tree sample plots, including a city road greening forest, yard greening forest, highway forest, and patch forest, were investigated. The results showed that the semivariogram curve models of eggs, larvae, and adults (pupae) of B. lineolata populations in different types of ash forests were all spherical, except the adults (pupae) in the patch forest plot were exponential, and the spatial distribution patterns were all aggregated. There were no obvious correlations between the aggregated behavior and living habitat of B. lineolata populations. However, the geostatistical parameters of the spatial correlation of B. lineolata populations in different types of ash forests were obviously different. The range (a), nugget (C₀), sill (C₀+C) of eggs, larvae, and adults (pupae) in the patch forest were lower than those of the other three types of forests. At the same time, the semivariogram model of adults (pupae) at the patch forest was exponential.
