Results of studies on the biology and injuriousness of Dasyneura ignorata Wachtl., Diptera, Cecidomyidae

, : Results of studies on the biology and injuriousness of Dasyneura ignorata Wachtl., Diptera, Cecidomyidae. Prace Naukowe Instytutu Ochrony Roslin 1974; 15(1): 11-57

An account is given of field and laboratory studies in Poland in 1965-69 on the biology and injuriousness of Dasineura ignorata (Wachtl) on lucerne there. The larvae overwinter in a coccoon just below the soil surface and pupate there in spring. The first adults are present from late April or early May, and adults of this generation are present until about mid-June. Adults of the summer generations emerge in July and August and are present throughout the growing season.
