Early detection of infestation by the emerald ash borer (EAB), Agrilus planipennis is extremely difficult; hence developing additional methods is desirable. We built on the successful use of canine scent detection for the invasive long-horned beetles Anoplophora glabripennis and Anoplophora chinensis and trained six dogs in detection of EAB. A first test series was performed to evaluate detection accuracy of five of these dogs. Seven different experimental settings were tested under single blind conditions: (1) forest nursery, (2) piles of firewood, (3) firewood on the ground, (4) ash logs on the ground, (5) old urban ash trees, (6) urban forest with ash trees and (7) natural forest with ash trees. In total, 214 positive samples were presented to the dogs, out of which 20 remained undetected. The experiments ascertained sensitivity (correct positives of all positives) ranging from 73.3 to 100 percent and specificity (correct negatives of all negatives) from 88.9 to 99.8 percent in the tested settings. This initial study demonstrates that trained dogs are able to detect EAB scent from sources such as larval galleries in bark/wood, frass, living or dead larvae or dead dry beetles. The numbers of tested dogs and test series were limited, and further studies are needed to confirm the initial results. However, the preliminary findings demonstrate the potential of the method particularly for inspection of wood or plants at entry points.

利用探测犬监测翡翠bore虫的研究进展

尽早发现翡翠bore虫（EAB）的侵袭性极难。因此，需要开发其他方法。我们基于成功地将犬用气味检测技术用于侵入性长角甲虫Anoplophora glabripennis和Anoplophora chinensis并训练了六只狗来检测EAB。进行第一个测试系列以评估其中五只狗的检测准确性。在单盲条件下测试了七个不同的实验设置：（1）森林苗圃，（2）柴堆，（3）地面上的柴火，（4）地面上的烟灰原木，（5）旧的城市烟灰树，（ 6）带有灰树的城市森林和（7）带有灰树的自然森林。总共向狗提供了214份阳性样品，其中20份仍未被发现。实验确定灵敏度（所有阳性的正确阳性）在73.3％到100％之间，而特异性（所有阴性的正确阴性）在测试环境中从88.9％到99.8％。这项初步研究表明，训练有素的狗能够从诸如树皮/木材，草皮，活的或死亡的幼虫或死的干燥甲虫。受测试的狗和测试系列的数量是有限的，需要进一步的研究以确认初步结果。但是，初步发现证明了该方法的潜力，尤其是在入口处检查木材或植物时。
