Abstract

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.

探测犬在翡翠灰蛀虫监测中的应用进展
早期发现绿宝石灰螟虫(EAB), Agrilus planipennis的侵扰是极其困难的;因此,开发其他方法是必要的。在犬类气味检测技术成功应用于入侵型光肩天牛(Anoplophora glabripennis)和中国天牛(Anoplophora chinensis)的基础上,对6只犬进行了EAB检测训练。进行了第一个系列测试,以评估其中5只狗的检测准确性。在单盲条件下测试了七种不同的实验设置:(1)森林苗圃,(2)柴火堆,(3)地上柴火,(4)地上白蜡树原木,(5)城市老白蜡树,(6)城市白蜡树森林,(7)白蜡树天然林。总共有214个阳性样本提供给狗,其中20个未被检测到。实验确定的灵敏度(所有阳性的正确阳性)范围为73.3%至100%,特异性(所有阴性的正确阴性)范围为88.9%至99.8%。这项初步研究表明,经过训练的狗能够从树皮/木材、杂草、活的或死的幼虫或死的干甲虫等来源中探测到EAB的气味。测试犬的数量和测试系列有限,需要进一步的研究来证实初步结果。然而,初步调查结果表明,该方法具有潜力,特别是在入境点检查木材或植物。

期刊介绍: The journal is inclusive of all subjects, geographical zones and study locations, including trees in urban environments, plantations and natural forests. We welcome papers that consider economic, environmental and social factors and, in particular, studies that take an integrated approach to sustainable management. In considering suitability for publication, attention is given to the originality of contributions and their likely impact on policy and practice, as well as their contribution to the development of knowledge. Special Issues - each year one edition of Forestry will be a Special Issue and will focus on one subject in detail; this will usually be by publication of the proceedings of an international meeting.
