RELATIONSHIP BETWEEN FALL CATCHES OF CAMPYLOMMA-VERBASCI (HETEROPTERA, MIRIDAE) IN TRAPS BAITED WITH FEMALES AND DENSITY OF NYMPHS IN THE SPRING

Male mullein bugs were captured in traps baited with live females in the fall within ten apple orchards in the Okangan Valley, British Columbia. When the catches of males from 14 September to 13 October 1987 were compared with limb tap samples of nymphs in the following spring, the relationships in the trap trees and trees adjacent to the trap trees were significant. When a synthetic pheromone is available for this mirid, prediction of economic injury levels may be made in the fall, 6-8 mo before egg hatch. -from Authors
