NCDA&CS to treat gypsy moth infestations
in Rockingham and Warren counties

RALEIGH - The N.C. Department of Agriculture and Consumer Services will soon treat a localized gypsy moth infestation in Rockingham and Warren counties in cooperation with the U.S. Forest Service and the Gypsy Moth Slow the Spread Foundation Inc. The treatments are anticipated to take place between June 2 and 12, depending on weather conditions and insect development. Follow @ncagriculture on Twitter for treatment updates.

Last summer and fall, field monitoring activities at these three locations showed that a reproducing population of the highly destructive gypsy moth exists and represents a threat to deciduous forests at the following locations:

  • Two blocks will be treated in Rockingham County, including a 174-acre block two miles west of Madison and a 517-acre block two miles northwest of Eden.
  • A 1,804-acre block in northwest Warren County about five miles south of the Virginia-North Carolina line.

Treatment will focus on disrupting mating patterns. Prior to normal gypsy moth mating periods, low-altitude fixed-wing aircraft will disperse miniature plastic flakes infused with the naturally occurring gypsy moth pheromone.

The pheromone saturates the treatment block so that male gypsy moths are not able to follow the natural pheromone scent trails released by the females.This decreases mating success and reduces the gypsy moth population. The pheromone is not harmful to humans, animals or plants, and it will not affect other insect species.

Gypsy moths feed on the leaves of more than 300 different species of trees and shrubs, predominantly hardwoods. When areas become heavily infested, trees may be completely stripped of foliage, leaving yard trees and entire forests more susceptible to attacks from other pests. Severe infestations often lead to tree death, especially of the more favored host species such as oaks.

Gypsy moth caterpillars can also pose health concerns for people with respiratory problems. The caterpillar hairs and droppings may cause severe allergic reactions in areas with a high density of gypsy moths.

NCDA&CS has addressed spot introductions of the gypsy moth across North Carolina since the 1970s. The department is working with 10 other states through the Gypsy Moth Slow the Spread Foundation Inc., and with other state and federal agencies to reduce the spread of the gypsy moth into uninfected areas in North Carolina.

Public hearings were held prior to the scheduled aerial treatment to receive input from landowners in and near the treatment block.
