Return of the Gypsy Moth

Like zombies that never die, gypsy moths are back on the Purdue campus. Gypsy moths were first reported in 2013 in an area known as Duhme Woods. In 2014, the State of Indiana conducted a gypsy moth eradication program. Eradication consists of treatments to reduce the larval population followed by pheromone mating disruption treatments to prevent mating. If successful, no viable eggs are laid and the population is eradicated. Eradication is followed by monitoring with pheromone traps. If no male gypsy moths are captured, the population is at least at an undetectable level and perhaps eradicated.

In 2016, pheromone monitoring traps detected male gypsy moths. This suggests that the population was not eradicated or that the area has been reinvested. This summer (2017) another eradication effort is planned starting with a public hearing on January 30.
