“…Discussion 141 Liebhold, 1998;Bossenbroek et al, 2001). However, given the difficulty in empirically measuring long-distance dispersal events, recent efforts have focused on developing a more thorough understanding of local dispersal since effective management strategies depend on behavior locally (Mercader et al, 2009(Mercader et al, , 2011bMcCullough and Mercader, 2012). The modeling framework in this dissertation not only provides a thorough description of local dispersal, but also provides some insight into the influence that local dispersal behavior has on non-local dispersal.…”

In this dissertation, we study integrodifference equations in patchy landscapes. Specifically, we provide a framework for linking individual dispersal behavior with populationlevel dynamics in patchy landscapes by integrating recent advances in modeling dispersal into an integrodifference equation.First, we formulate a random-walk model in a patchy landscape with patchdependent diffusion, settling, and mortality rates. We incorporate mechanisms for individual behavior at an interface which, in general, results in the probability-density function of the random walker being discontinuous at an interface. We show that the dispersal kernel can be characterized as the Green's function of a second-order differential operator and illustrate the kind of (discontinuous) dispersal kernels that arise from our approach. We examine the dependence of obtained kernels on model parameters.Secondly, we analyze integrodifference equations in patchy landscapes equipped with discontinuous kernels. We obtain explicit formulae for the critical-domain-size problem, as well as explicit formulae for the analogous critical size of good patches on an infinite, periodic, patchy landscape. We examine the dependence of obtained formulae on individual behavior at an interface. Through numerical simulations, we observe that, if the population can persist on an infinite, periodic, patchy landscape, its spatial profile can evolve into a discontinuous traveling periodic wave. We derive a dispersion relation for the speed of the wave and illustrate how interface behavior ii

“…However, since control strategies focus on satellite populations in an effort to slow the spread, a better understanding of local dispersal behavior in these satellite populations is required (Mercader et al, 2009(Mercader et al, , 2011bMcCullough and Mercader, 2012).…”

“…In 2008, a pilot project to slow the impact of EAB, called SLAM (SLow Ash Mortality) was initiated as an integrated strategy for dealing with recently established outlier sites [100]. The SLAM pilot project used girdled ash trees, a systemic insecticide, and removal of ash trees [100]. Long-term conservation of ash by reducing EAB populations in North America have invested in classical biological control and three parasitoids native to China are currently being released in the United States [105].…”

“…The manufactured sticky prism traps currently used for EAB are visually attractive purple and green made from corrugated plastic covered in sticky glue, which are typically baited with host volatile lures [88,90]. Efforts in the United States include deploying thousands of these baited purple prism traps [100,101]. Purple traps generally catch more females than males, and green prism traps (when hung~13 m in the canopy) will catch more males than females [90].…”

“…These insecticide treatments are most effective when applied as soon as possible to relatively healthy trees, as trees that have lost more than 50% of its crown are usually too far gone to save [104].

Abstract:The objectives of this review paper are to provide an overview of issues related to forest health and forest entomology, explain existing methods for forest insect pest detection, and provide background information on a case study of emerald ash borer. Early detection of potentially invasive insect species is a key aspect of preventing these species from causing damage. Invasion management efforts are typically more feasible and efficient if they are applied as early as possible. Two proposed approaches for detection are highlighted and include dendroentomology and near infrared spectroscopy (NIR). Dendroentomology utilizes tree ring principles to identify the years of outbreak and the dynamics of past insect herbivory on trees. NIR has been successfully used for assessing various forest health concerns (primarily hyperspectral imaging) and decay in trees. Emerald ash borer (EAB) (Agrilus planipennis), is a non-native beetle responsible for widespread mortality of several North American ash species (Fraxinus sp.). Current non-destructive methods for early detection of EAB in specific trees are limited, which restricts the effectiveness of management efforts. Ongoing research efforts are focused on developing methods for early detection of emerald ash borer.
