Feeding rates of adult Sitona cylindricollis Fahraeus collected at different seasons and maintained at different temperatures and light regimes were compared in the laboratory. Feeding rates were highest for Weevils collected in fall and lowest for those collected in midsummer. Weevils collected in spring and summer ate more when the temperature was 75°F, and fall-collected weevils ate more when the temperature was between 75° and 90°F. Weevils when exposed to complete darkness, but newly emerged weevils collected in July fed significantly more in the dark than in the light. These responses to light corresponded also with their daily period of activity in the field. Results of this study will be applied in the search for resistance in sweet lover.
