Community of potential predators of hemlock woolly adelgid (HWA) in an
eastern hemlock forest
eastern hemlock forest
Project Description: In 2000,
Sasajiscymnus tsugae, a predatory lady
beetle of HWA was released into the
MRGP. The biocontrol agent was not
observed following 2001. However, the
MRGP hemlock forest is relatively healthy
and how S. tsugae and other potential
predators contribute to our hemlock’s
survival is unknown. In this exploratory
study, Wynter will be “hunting” for our
lady bird beetle, while surveying the
community of potential other HWA
predators across hemlock stands varying
in infestation.
