Balsam woolly adelgid is associated with which host and origin?

Explanation:
Balsam woolly adelgid targets true firs, especially balsam fir, and is not native to North America. It originated in Asia and was introduced into the United States, with the first detections in New Hampshire, then spreading west to Oregon. That combination—a true fir host and an introduction from Asia that began in New Hampshire and moved to Oregon—best matches the grown knowledge of this pest. The other hosts listed (Douglas fir, hemlock, ponderosa pine) are not the primary hosts, and the insect is not native to the Pacific Northwest.
