Detection of Halyomorpha halys by detector canines from dead trees in the natural landscape.

1Yes refers that canines indicated the presence of H. halys; No refers that canines indicated the absence of H. halys.2Dead trees with the favorable characteristics (standing, DBH >19 cm, oak or locust) were identified as likely overwintering sites of H. halys based on the results from human surveyors.3All trees indicated by canines were destructively sampled during the survey (n = 11). For trees that canines did not show positive indications (n = 176), 50 of them were randomly selected and destructively sampled after the survey.
