| Summary: | The black or roof rat (Rattus rattus) was introduced by Europeans into South and Middle America in the sixteenth century, and was established in America by the beginning of the 1700s (1). Rattus norvegicus, the wharf or Norway rat, of supposed Asian origin, arrived in the United States on ships about 1775 (1). This latter species has supplanted the smaller and more urban black rat over much of its former range (2,3). |
