Although spreading rapidly through the Great Smoky Mountains and through
the rest of the south, there are several methods that can be used to
treat
and control the infestation of the Hemlock Woolly Adelgid (HWA), both chemical
and biological. Chemical controls primarily include insecticides, which can be difficult to administer to widespread and remote populations. Biological control of the serious HWA problem may be attained by use
of predatory insects. The most effective biological weapon against
HWA currently known is the tiny Japanese ladybird beetle, Pseudoscymnus tsugae, or, the P.t. Beetle. Links to information on control of the HWA can be found by clicking on the "hot spot" links in the iPIX™ picture below.
