Simulated damage (artificial debudding) was used to establish preliminary economic injury threshold for Amathes c-nigrum (L.) in ‘Red Delicious’ apple trees. Production was unaffected by 2 levels of debudding. 50 and 75%, but the debudding produced a significant increase in fruit size and number of new shoots. Injury at the high level for 2 consecutive years caused a substantial (97%) loss of return bloom the 3rd year; however, there were sufficient blossoms to set a normal crop the 3rd year.
