During the summer of 1949 an outbreak of flea beetles on both sweet and silage corn occurred at Armstrong, British Columbia. The first damage to the corn was noticed by the growers in early July, and by mid-August was so severe in some instances that the crop had to be cut for ensilage before the cobs were mature. The adult beetles confined their feeding to the leaves and cob husks, causing decided browning and drying out of these areas.
