Our work has substantially advanced our knowledge of native and invasive forest insect ecology, impacts and management. Recent research on EAB, in particular, has contributed to understanding the population dynamics, economic and ecological impacts, and host preference of this invader. Other studies on management strategies and control options have substantially improved the outlook for landscape and urban ash trees. Results from our EAB projects have contributed to federal, state and municipal policies and decisions across much of the US, as well as Canada and Europe.

Program Description


Nearly all students in 407 plan to work in forestry or natural resource management or in arboriculture/ landscaping. This is typically the first and usually the only exposure to entomology these students encounter. My goal is to ensure students can effectively identify and distinguish between major and minor insect pests affecting trees, accurately diagnosis insect-related damage and distinguish tree problems caused by non-insect factors (pathogens, abiotic problems). I try to provide students with a solid understanding of pest management options, exposure to pros and cons of commonly used pesticides, biocontrol, silvicultural or cultural tactics, and basic IPM. I build a substantial amount of ecology (e.g., population dynamics, bottom up- and top-down regulation of herbivores, invasion ecology, climate change impacts) to provide students with the background they need to make sound decisions and develop effective strategies to protect trees or manage healthy forests. I draw on real-life examples from my research and extension experiences to challenge students to consider how politics, economics and public perception can affect forest pest management. In the ENT labs, we use a collaborative, active learning process to engage students while covering a considerable amount of information in a short time frame. We do three joint entomology-pathology field trips in spring that enable students see interactions of insects, pathogens and site conditions.

My research, which focuses on forest insect ecology and management, runs along a continuum of relatively basic to applied studies that enhance our understanding of insect and forest ecology while generating practical information to address important problems. Most activities in recent years have involved invasive forest insects, largely because of the economic and ecological costs associated with several major insect pests. Over the past decade, I led numerous projects related to EAB, ranging from detection and survey methods, population dynamics and spread, host range and interspecific host preference, ecological and economic impacts, systemic insecticides to protect landscape trees, and strategies for area-wide EAB management. In recent years, I participated in interdisciplinary working groups to address invasion pathways, geographic distribution and economic impacts of invasive forest pests in the US, and factors related to successful invasive pest eradication, Other recent and current efforts include studies related to beech bark disease spread and impacts in Michigan and potential control options for beech scale, which is of interest to landscapers and arborists. We are also using data collected from a statewide survey for targeted exotic pests to evaluate multi-species attraction of cerambycid pheromones and species composition of woodborer communities in different forest cover types.


My extension program is highly integrated with my research on forest insect ecology and management. Nationally, I continue to provide practical advice and objective information related to EAB and invasive forest insect ecology to a wide range of groups, including federal, state and municipal resource managers, regulatory officials, private arborists and landscapers, and property owners. These activities have played a major role in changing perceptions of EAB, particularly in recently infested states and municipalities, where EAB “management” is replacing the doomsday scenarios of a few years ago. I also provide EAB-related information to scientists in Russia, the European Union and Canada. Much of this information was generated by the research conducted by my students, collaborators and myself. I continue to direct the national website, regarded as the primary source of objective EAB information. Within Michigan, I work frequently with MDARD and MDNR personnel to address issues related to invasive and native forest insects (e.g., federal and state quarantines, exotic pest surveys, silvicultural tactics to reduce pest damage). We recently began a major project that links MSU Extension foresters, risk modeling and public education to expand awareness of specific high risk pests that are likely to cause serious damage if they become established in Michigan. I also answer questions and provide management suggestions for a variety of tree-feeding insects including gypsy moth, Christmas tree pests, control of insect pests on landscape trees and silvicultural management for bark beetles, woodborers and conifer defoliators.
