Table 3: Index of association of _B. olease_ males and female spatial clusters, calculated for each sampling date and the total catches, following the SADIE procedure. Values in bold are significant at \(p\) \(<\) 0.05. In the case of Italy, male and female distributions overlapped in most of the experimental plot, with extended areas of positive association (Figure 6). Hot spots in both sexes were limited to BT traps. Negative association was observed mostly in low-density areas. In Lebanon and Spain, population levels were high, with some male hot spots reaching 450 trapped individuals. In Lebanon, female and male distributions were strictly associated and each BT corresponded to a hot spot. No negative association was observed (Figure 7). Figure 5: Contour maps of the male and female distributions and their spatial association calculated with SADIE in the experimental site located in Greece. The grey scale indicates the number of captured individuals in male and female maps. In the association map, red and blue colours correspond to areas with positive and negative association, respectively. Red squares indicate baieted traps and black circles indicate unbaieted traps. Coordinates are expressed in the UTM geographical system. Figure 6: Contour maps of the male (on the left) and female (on the right) distributions and their spatial association (in the middle), calculated with SADIE in the Italian experimental site. The grey scale indicates the number of captured individuals in male and female maps. In the association map, red and blue colours correspond to areas with positive and negative association, respectively. Red squares indicate baieted traps and black circles indicate unbaieted traps. Coordinates are expressed in the UTM geographical system. Figure 7: Contour maps in grey report the male and female distributions in the Lebanon site; in the middle the map of their spatial association calculated with SADIE. The grey scale indicates the number of captured individuals in male and female maps. In the association map, red colours correspond to areas with positive association. Red squares indicate baieted traps and black circles indicate unbaieted traps. Coordinates are expressed in the UTM geographical system. In Spain, the areas with the highest concentrations of both sexes generally overlapped with the locations of baited traps (BTs), confirming their effectiveness as attraction hot spots in the field.
