The aim of this study was to assess the population density of the first generation of C. ohridella at eight sites in the urban area of České Budějovice, Czech Republic in two consecutive years. The results revealed high variability in the mean percentage of the leaf area damaged ranging from 1.43% to 31.00% and from 0.26% to 23.40% in 2012 and 2013, respectively. Spatial analysis revealed no autocorrelation in damage among sites indicating that the distribution of C. ohridella is random and not affected by the level of infestation at neighbouring sites. The number of moths that emerged in spring was positively correlated with the damage done by the first generation of C. ohridella the previous year. Similarly, the total number of parasitoids that emerged was correlated with the number of moths that emerged.
