Developing Novel Molecular Detection Techniques For Hemlock Woolly Adelgid (Adelges Tsugae), Meg Sanders

Masters Theses

Hemlock forests in eastern North America face a deadly threat: the invasive insect, hemlock woolly adelgid (HWA), Adelges tsugae. Early detection of this pest remains a key focus for management groups to ensure rapid response to control and stop the spread of HWA. In Chapter II, our goals were to develop an affordable, easy-to-use trap that is compatible with airborne eDNA sampling techniques and assess its efficiency as a monitoring tool for HWA. We tested three potential trap designs (i.e., passive trap, funnel trap, and motorized trap) against a standard sticky trap. Our passive, funnel, and motorized traps estimated …

Invasive species are a major issue around the world and more specifically in our U.S. National Parks. Ranging from plants to insects to animals, invasive species are a greater threat than many may imagine. The impact that invasive species have on an ecosystem encompasses more than taking over a native species’ environment; it includes competing for food, water, and other resources, as well as having an adverse effect on our economy and threatening us with deadly diseases. Many factors lead to the cause of spread of invasive species, but all point back to human interference, from purposely spreading invasive species …
