The purpose of this study was to explore the potential of monitoring field populations of the NCR and WCR beetles with pheromone baited sticky traps. Predictions of CRW infestations in corn fields on a single field basis have yet to be achieved. The objectives of this study were: 1. To determine the effects of trapping procedures on CRW beetle trap catch variability: trap design, trap height, pheromone age, pheromone concentration and beetle density. 2. To determine the impact of environmental factors on daily trap catch variability: temperature (OC), wind speed (m/sec), and relative humidity (%) taken at hourly intervals. 3. Correlate CRW beetle-per-plant counts with daily trap catch on a field-to-field basis for control recommendations.
