Does Pheromone Trap Placement Height Change Bollworm Catch Accuracy?
A controlled field trial across 24 cotton plots finds trap height a stronger predictor of catch accuracy than trap density.
- ▸Canopy-height trap placement outperformed both above- and below-canopy placement at every density level tested.
- ▸Trap density had no statistically significant effect on catch accuracy once height was controlled for.
- ▸Findings suggest extension guidance should prioritize placement height over simply adding more traps.
