ON THE TWO SPECIES OF BRUCHIDIUS (COLEOPTERA: BRUCHIDAE) ESTABLISHED IN NORTH AMERICA

Abstract

AbstractThe European Bruchidius ater (Marsh.), first discovered in Massachusetts in 1918, and later in Virginia, is here recorded from Rochester, N.Y. In addition to Cytisus scoparius (L.) Link, its known host in the United States, the insect was reared from seeds of Petteria ramentacea (Sieber) Presl and Laburnum alpinum Bercht. and Presl at the New York locality. All three plants are introductions from Europe. Bruchidius unicolor (Ol.) was recognized in 1965 when it was discovered in British Columbia breeding in the seed pods of Onobrychis viciaefolia Scop. A single specimen, collected in Nicola, B.C., in 1922, indicates that the insect has been present in southwestern Canada for a considerable time.
