Corn plant damage (an index of SCB density) in fields with different cropping histories was initially concentrated either on the field edge next to last year's corn in rotated fields, or the edge next to the overwintering site in nonrotated fields. Although damage patterns and trapping studies suggested that SCB dispersal into fields was primarily by walking, SCB are capable of strong flight. Weevils of both the overwintered and summer generations were caught in flight traps. Diurnal activity patterns of adult SCB were often bimodal; peak numbers of adults were found on plants and caught in pitfall traps in late morning and mid- to late afternoon. Changes in adult activity appeared to be better explained by changes in temperature than by changes in light intensity. Least activity occurred when temperatures were above 30°C or below 20°C.}, number={4}, journal={ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA}, author={WRIGHT, RJ and VANDUYN, JW and BRADLEY, JR}, year={1983}, pages={572–581} } @article{wright_van duyn_bradley_1983, title={Seasonal phenology and biology of the Southern corn billbug in eastern North Carolina}, volume={18}, number={3}, journal={Journal of the Georgia Entomological Society}, author={Wright, R.
