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 [...]
