Research Highlights

An Integrated Pest Management Strategy for Hemlock Woolly Adelgid (2020)
SRS-2020-23 Land managers aiming to protect hemlock trees and control hemlock woolly adelgids (HWA) have a new resource from the USDA Forest Service: a technology transfer publication with guidelines on integrating chemical and biological control of the invasive hemlock woolly adelgid. The guide synthesizes current knowledge and presents a strategy for prolonging hemlock health: limited use of insecticides combined with establishing HWA predators on untreated or previously-treated trees. It offers guidelines a for implementing, monitoring, and assessing the strategy, which can be adapted to incorporate additional management tools as they are developed.

More sunlight: a solution in the fight against an invasive tree-killing insect (2017)
SRS-2017-143 Eastern hemlock, a species with key ecological roles in eastern forests, is being killed throughout its range by an invasive insect, the hemlock woolly adelgid. Using artificial shade treatments on potted hemlocks, Forest Service scientists and their partners showed that elevated sunlight levels improved seedling growth and carbon status and dramatically reduced numbers of hemlock woolly adelgid on the branches. The findings suggest that forest management practices, such as thinning or creating small canopy gaps, that increase sunlight exposure on hemlocks could be valuable tools in the effort to manage and conserve eastern hemlock.

New Insights Into Trapping the Redbay Ambrosia Beetle (2016)
SRS-2016-176 The redbay ambrosia beetle carries the pathogen that causes laurel wilt, a disease which has killed millions of redbay and sassafras trees in the southeastern U.S. A recent study by Forest Service scientists provides new insights into how the invasive pests responds to traps that are baited with lures that smell like a host tree.

Using Predators and Chemicals together to Protect Hemlock Trees. (2015)
SRS-2015-241 A non-native insect, the hemlock woolly adelgid, is eliminating an ecologically important tree species, eastern hemlock, from southern Appalachian forests. Systemic insecticide applications and predator beetle releases are being combined to fight this invasive pest. In a study in northern Georgia, trees previously treated with imidacloprid insecticide had better crown health and eventually supported as many predator beetles as untreated trees, showing promise for an integrated pest management approach.
