Officials Are Warning People About Gypsy Moth Caterpillars And The Serious Rashes They Cause by Ileana Paules-BronetAuthor: Ileana Paules-Bronet. Results from 15 published field and laboratory studies were used to construct a table showing the suitability to gypsy moth (Lymantria dispar) of foliage of all trees native or common in the USA. Foliage suitability to the moth is a trait that is correlated among closely related species. It is thus possible to extrapolate foliage suitability of North American tree species for which no Cited by: 9.

Abstract The gypsy moth,Lymantria dispar, and the northern tiger swallowtail,Papilio canadensis, overlap geographically as well as in their host ranges. Adult fe-male swallowtails are incapable of distinguishing be-tween damaged and undamaged leaves, and the opportu-nities for competition between these two species are nu-merous. Gypsy Moth Regulations When Moving to California. Gypsy moth caterpillars can be extremely destructive to trees, including hardwoods, though anything with leaves is game to these pests. They were brought to the U.S. in by a French scientist.

The best way to attack a gypsy moth problem is to attempt non-chemical pest management strategies first. There are inherent risks associated with all pesticides, and a number of steps that can be taken as alternatives to chemical insecticides. Gypsy moth caterpillars prefer to eat oak, birch, apple, willow, linden, hawthorn, and sweet gum trees.
