The European gypsy moth has an exceptionally broad host range (>250 species). Favored host species are oak, apple, alder, basswood, birch, poplar, sweetgum, willow, and hawthorn. Less favored are hickory, maple, cherry, cottonwood, elm, blackgum, larch, sassafras, and hornbean. Some mortality even occurs in white pine.


Commodities Affected:
Forestry and Natural Areas, Nursery, Ornamentals, and Turf



The European gypsy moth causes widespread defoliation, resulting in reduced growth, loss of vigor, mortality, and reduces aesthetic, recreational, and wildlife values. Gypsy moth larvae can be a serious nuisance in urban and recreation areas.



In 2006 the European gypsy moth was found established in the following 11 Indiana counties: Allen, DeKalb, Elkhart, LaGrange, Lake, La Porte, Noble, Porter, St. Joseph, Steuben, and Whitley counties.
