Exploration for and importation of natural enemies of the gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), in North America: an update

A compendium report of explorations, importations, and releases of exotic natural enemies of the gypsy moth in the United States, published in 1981, is updated. Changes in scientific nomenclature of the natural enemies, and information on explorations and importations, that have occurred from 1978-1985, and literature published during that period, are reported. A complete record of importations from 1963-1985 is provided. A pupal parasite, Coccygomimus disparis (Viereck) (Ichneumonidae), is established in the United States. Meteorus pulchricornus (Wesmael) (Braconidae), has been recovered and may be considered provisionally established. Data on importations of gypsy moth natural enemies into Canada, which began in 1976, are also summarized.
