Acclimatization of Tarachidia candefacta Hubn. (Lepidoptera, Noctuidae) in the south of the European part of the USSR


, : Acclimatization of Tarachidia candefacta Hubn. (Lepidoptera, Noctuidae) in the south of the European part of the USSR. Entomologicheskoe Obozrenie 52(4): 759-767

The main ecological features of a population of Tarachidia candefacta (Hb.) introduced from southern Canada into the Soviet Union for the biological control of the weeds Ambrosia artemisiifolia and A. psilostachya were studied under laboratory and field conditions in the Black Sea coast area of the Krasnodar region. The low temperature threshold for development was found to be 11 deg C, and the sum of effective temperatures needed for completion of a generation 440-470 degree-days.
