In this study, the spatial distribution of the larvae of three Artemisia ordosica (Krasch 1946) boring species (Sphenoptera sp, Holcocerus artemisiae (Chou & Hua 1986) and Adosomus sp) was analyzed using geostatistical methods. The best-fitted isotropic semivariogram model for Sphenoptera sp, H artemisiae and Adosomus sp was the spherical model. The results showed that the degree of spatial autocorrelation among the populations of the three species was high and their spatial distribution was aggregated. The degree of aggregation was highest for Sphenoptera sp larvae, followed by the H artemisiae and Adosomus sp populations, which in absolute terms showed a medium degree of spatial aggregation. Isovalue maps of the spatial distribution of interpolated population densities of these borer populations were generated with the Kriging method. The results indicated that the linear association between measured and estimated population densities was weak in the entire study are. These results provide a new theoretical tool for the study of pest species, which enables the forecast of changes and trends in population density on a large scale, as well as the implementation of suitable strategies for control.
