Current Research
I am conducting research on an invasive insect, the hemlock woolly adelgid,
Adelges tsugae. This research is focused on developing biological controls and
host resistance to the adelgid, which is native to Asia. I spend part of each
year in China and Japan searching for its natural enemies and import those which
seem most promising for biological control to the Forest Service?s Quarantine
Laboratory located in Ansonia, CT. Several species of lady beetles have been
imported, evaluated for desirable biological traits and risk to non-targets. Two
of the lady beetles are being mass reared, released in the field and monitored
for efficacy. Research to develop host plant resistance to the adelgid is
examining the world?s hemlock species to identify tree genetics and chemistry
associated with resistance. Currently, in cooperation with the National
Arboretum, hybrids between Chinese hemlock and native Carolina hemlock are being
developed for both resistance to the adelgid and desirable growth
characteristics.
Why is This Important
The hemlock woolly adelgid is a serious threat to the two hemlock species in
the eastern United States, Tsuga canadensis and T.
caroliniana. Because these hemlocks are long-lived and have dense plant
canopies, they provide a unique habitat and have a role in eastern forests which
cannot be duplicated by other tree species. Without co-evolved resistance or
natural enemies, the adelgid quickly attains high densities which cause a slow
decline in hemlock health and eventual tree death. This research will establish
the natural balance between the insect that will maintain it below damaging
thresholds
Future Research
This research to establish natural controls of an accidentally, introduced
pest insect will continue. This is a difficult task which requires cooperation
with researchers overseas. Recent advances in communication technology and GIS
provide increased opportunities that were not available a few years ago.
Hopefully, I will be able to utilize this increased capacity to share knowledge
globally to prevent potential and reduce the threats of other nonnative insects
to our forests.
