Beneficial insects; Insect pests. - 100 - SUMMARY OF INSECT CONDITIONS IN THE UNITED STATES V 1959 INSECTS AFFECTING MAN AND ANIMALS FACE FLY (Musca autumnalis) became abundant and seriously annoying to cattle in several states during 1959. Specimens were collected in 13 states for the first time during the year. The states, in order, according to when they were reported, were Virginia, Ohio, Indiana, Illinois, Pennsylvania, Michigan, Massachusetts, New Hampshire, Delaware, New Jersey, West Virginia, Vermont and Wisconsin. The pest became quite heavy in western Pennsylvania, although it was present in all parts of the State, and caused much concern to cattle and home producers. In New Jersey, face fly appeared statewide as an annoying pest of dairy cattle, particularly in clustering about the eyes of animals and producing irritation. First collections of face fly were made in August in New Castle County, Delaware, and in Chittenden County, Vermont. Infestations were reported moderate through- out Maine during August, and were heavy on the faces and eyes of cattle during late summer in Bath, Highland and Montgomery Counties, Virginia. Face fly was first reported in Indiana at Randolph on June 3. It spread rapidly and generally over the State and caused extreme annoyance to cattle in the northern half, where it also entered houses. The first record in Illinois was on June 3 at St. Joseph, Champaign County. Since that date, the species was collected in 53 counties in the northern two-thirds of the State. One hundred or more flies per animal were observed in some herds in the eastern portion of the State north of Champaign and also in Whiteside County in the northeast. Much annoyance was caused to cattle, particularly around faces and heads. The introduction, wide distribu- tion and abundance of face fly in Ohio was one of the outstanding features of the season in that State. Adults of this species accumulated on the faces of cattle
