USDA Develops Hemlock Hybrids Tolerant of HWA

New hemlock hybrids that are tolerant to the invasive insect known as hemlock woolly adelgid have been created by U.S. Department of Agriculture (USDA) scientists. Geneticist Richard Olsen and horticulturist Sue Bentz of USDA’s Agricultural Research Service (ARS) teamed up with Forest Service entomologist Mike Montgomery to breed and select these tolerant hybrids. Olsen and [...]

Investigating Host Resistance Using Scanning Electron Microscopy

by Kelly F. Oten1, Allen C. Cohen2, John B. Strider1, and Fred P. Hain1 Abstract This study uses scanning electron microscopy (SEM), a surface-imaging technique, to investigate feeding behaviors of the hemlock woolly adelgid (HWA), Adelges tsugae Annand. Understanding feeding behavior directly relates to the pest-host interactions which can elucidate resistance mechanisms in hemlocks. Salivary [...]

Golden Leaf Foundation Provides Support for Christmas Tree and Hemlock Research

A collaboration of scientists joining forces against the balsam and hemlock woolly adelgids, insects that threaten Fraser fir and eastern hemlock trees, respectively, recently got new ammunition. A $65,000 grant from the Golden Leaf Foundation will allow the scientists to start developing gardens of woolly adelgid-resistant trees. Chaired by Dr. Fred Hain, forest entomologist at [...]
