## 1 Introduction
delicatula_ while avoiding trapping any non-target insects or debris. Taking all the information collected from their observations, they were able to determine which kinds of traps worked best and what improvements could be made to already existing traps to increase their success rates. In a similar fashion, a study conducted by [PERSON] et al. in 2018 aimed to determine if chipping could be used as a successful mitigation strategy against _L. delicatula_[7]. Their results found that there were no nymphs present in the barrels with the chipped tree material, while there were about 500 nymphs present in the control barrels with the tree material intact [7]. Based on the results of this study, researchers were able to determine that chipping the host tree _A. altissima_ during _L. delicatula_'s overwintering season would be a useful mitigation strategy against this pest [7]. Other preventative methods that have been researched include the use of various insecticides [8], as well as an innate egg parasitoid [9] to help control population numbers. Previous studies have employed similar methods to determine the odor profiles of various types of insects, including larvae, pupae, flour beetles, and maggots [10; 11; 15]. Biosecurity detection dogs have been trained to detect invasive insects and pests before; for example, in a study by [PERSON] et al. in 2020, detector dogs were trained using scent extracts and dead samples of _Musgraveia sulciventrits_ (_AFD_) [4]. The results from this study found that odor extracts could be used as a training aid for detector dogs as a substitute for live samples, with the dogs still able to be successfully trained in identifying their target odor [4]. Another study was performed to determine if dogs could be trained to detect red imported fire ants, _Solenopsis invicta_ (_Buren_), as well as locate the ants' nest in a field setting [16]. It was determined that the dogs could not only detect the fire ants, but they could also discriminate it from three other species, as well as locate the nests [16]. Dogs have also previously been trained to detect bark beetle-infested trees using a pheromone component from _Ips typographus_ (_Linnaeus_) [17]. The study found that dogs could be trained to detect and locate infected bark from 100 m or more, which showcases the diverse use of detector dogs [17]. In a similar study conducted by [PERSON] et al. in 2021, tests were conducted to determine if detector dogs could be trained with dead _L. delicatula_ egg masses and if this identification could then be transferred to detecting live egg masses [12]. The study found that the dead _L. delicatula_ eggs could be used as a potential training aid for the detector dogs; however, while these studies were also performed in a lab, there was no chemical odor profile evaluation on the utilized samples [12]. An important suggestion for future study in mitigation strategies using canine detection teams is the importance of testing alternate insects' odor volatiles to better narrow the target odor source. This work was continued in a similar study by [PERSON] et al. [14], who attempted to train detection dogs to alert to cold-killed SLF masses. Several distractor odors were used, such as crickets, red maple tree bark, grasshoppers, and tree of heaven bark. This was to ensure that the dogs were trained on the scent of the cold-killed SLF egg masses and not other insects. In this study, it was determined that detection dogs could be a valuable tool in the detection of SLF eggs, as the dogs used in their study had specificity and sensitivity rates greater than 95% [14]. Various mitigation and prevention techniques have been developed to deal with the spread of SLF, using canines as biological detectors for this invasive species as an up-and-coming technique for pest management efforts.
