Hyadaphis tataricae (Aizenberg). an aphid known from eastern Europe, is rapidly becoming a pest on ornamental honeysuckles (Lonicera spp.) throughout the north-central states.
The source of the infestation is not known but it could have been introduced from eastern Canada where it has been present since 1976 (Boisvert et aI. 1981), or by separate introduction from eastern Europe. The first observations in the United States were made in the north-eastern corner of Illinois (Lake County) in 1979 (Voegtlin 1981). Observations of damage levels in that area support the hypothesis that its introduction to the north-central states originated there
