The bacterium known as Bt produces a toxin that has long
been used to control some insect pests. Researchers at the University
of Wisconsin-Madison have found the ability of Bt to kill gypsy moth
caterpillars is helped by the bacteria that are found in the guts of
Graduate student Nichole Broderick is the lead author of
the study, which is published in the Proceedings of the National
Academy of Sciences. Broderick says knowledge of how Bt kills
caterpillars could lead to better use of Bt in the environment.
“It would be useful in terms of improving the effectiveness in field
applications and making perhaps methods of control more specific to
the pest that you’re going after.”
That could help target the nasty insects without harming the beneficial
