Rautapaa, M.; Markkula, M., 1972: Acclimation of Sitona hispidulus Fabr. and Sitona decipiens Lindb. (Col. Curculionidae) to falling temperatures. Annales Entomologici Fennici 38(1): 51-59
In a further study of Sitona hispidulus (F.) and S. decipiens Lindberg in Finland, seasonal variations in activity and cold-hardiness were investigated in 1966, weevils being collected from clover in August and September and kept with leaves of red clover in an insectary from which adults were taken for laboratory testing at intervals of about three weeks.
