The Scope of the Problem

• Many Threats– Insects– Diseases– Invasive Plants

• Many Efforts– Eastwide, FS-wide– Much needs to be done

Southern Research StationSRS Mission: To create the science and technology needed to sustain and enhance southern forest ecosystems and the

benefits they provide.

Southern Pine Beetle and Invasive Insects

- Ambrosia beetles, hemlock woolly adelgid, emerging threats

Termites

Diseases and Invasive Plants

- Sudden Oak Death, Cogongrass

Page 5: Invasive Species in Eastern Forests: Forest Service Research Efforts and Strategies

The Scope of the Problem• Current efforts

– Redbay Ambrosia Beetle– SPB

• Protection

• Detection

– Cogongrass• Biology

• Eradiction

What lies ahead– Sirex Woodwasp

Redbay Ambrosia BeetleXyleborus glabratus

Female

- Native of southeast Asia

- First in US in Georgia 2002

- Uncommon, not deadly in Asia

- Carries a wilt fungus

SRS Research on RAB

• Studying biology and host associations of RAB• Identifying hosts susceptible to wilt fungus• Developing baits and trapping system for RAB• Evaluating RAB population trends over time • Developing control strategies utilizing chemical

attractants and insecticides.• Movement into other hosts (avocado)
