Figure 3
Characterization of dead trees used by Halyomorpha halys for overwintering sites in the forested areas identified by human surveyors.
Numbers in the parentheses are the number of dead trees with given characteristics. aLarger refers to trees with diameter at breast height (DBH) >19 cm; smaller refers to tree with DBH ≤19 cm. nbug = number of trees harboring H. halys.
