Activity of Fenusa dohrnii (Hymenoptera: Tenthredinidae) on Alnus in the northcentral United States
Environmental Entomology 20 (2), 534-539
Abstract: Seasonal activity of the European alder leaf miner, Fenusa dohrnii (Tischbein), on Alnus was examined at Midland, Mich., and Rhodes, Iowa. Oviposition activity, adult trap catch data, and leaf-mining activity all indicated the presence of three generations of leafminer per year. Changes in population levels seemed to correspond with weather phenomena, especially rainfall. The presence of five feeding instars was confirmed.
