WEST LAFAYETTE, Ind. (WLFI) – Treatment to control the gypsy moth infestation at Purdue is delayed until Monday because of weather conditions.
The treatment had been scheduled to happen on Monday, and then pushed back to Friday. But weather conditions were not adequate for either of those days, and will now take place Monday, May 19, still dependent on weather.
As News 18 originally reported in January, entomologists are working to stop the invasive gypsy moth from spreading. It was found on campus last June.
Department of Natural Resources Compliance Officer Scott Kinzie told News 18 the moth feeds on more than 500 kinds of trees, and they can kill trees if they feed for long enough.
During treatment, a plane will fly over Purdue releasing a material called BTK Foray 76-B, which DNR said disrupts the moths’ digestive systems.
Experts said they need wind speeds at 10 to 12 miles per hour or lower, and no rain for a minimum of 6 hours after the treatment.
DNR said the treatment flight will start at sunrise and be completed in 30 minutes to an hour.
A mating disruption treatment is planned for late June.
