Living With Gypsy Moth Eradication

Gypsy Moth has become a perennial pest in most of the Northeastern United States. It has been slowed from establishing in Indiana by an effective program of monitoring followed by eradicating small populations such as the recent Gypsy Moth eradication at Purdue. Eradication does not work for large populations but is effective against small ones. The key is to find them when the population is small and eradicate before the population gets out of hand.

Gypsy Moth eradication is also used by the Canadian Government to slow the spread. An infestation in Surrey, British Columbia is expanding and will be targeted for eradication. The projected cost is $1 million. The benefit? CBC has this quote from Tim Ebata of the Ministry of Forests &c,

Because we have agreed to be gypsy moth-free in Western North America, our trading partners in the U.S. would quarantine us—or impose some kind of trade restriction if we had infested material that would move across the border.

Invasive species are an economic threat that keeps entomologists busy.
