The principal focus of my research
is to investigate the bionomics
of the sweet potato whitefly, as
well as other whiteflies, in order
to devise methods of control that
are not pesticide dependent. To
this end, my laboratory has largely
focused on examining their migratory
patterns. We have discovered that
there are both migratory and nonmigratory
forms within some whitefly populations.
We have examined the morphology,
behavior and physiology of each.
It is our goal to generate the biological
information necessary to construct
predictive models for the time,
direction and distance of whitefly
migration between crops. We are
also interested in investigatining
the biology of their natural enemies,
particularly dispersal by their
parasitoids.
