The approach will be to be as rigorous as possible with chemical purity, lure dosing and assessment of pheromone release ratios and then add a graded or stepwise level of “stress” on the pheromone formulations. Lures made with rubber septa have been known to be unstable with some aldehyde-containing pheromone blends. To circumvent this problem, we will exhaustively extract rubber septa, plastic vials and tubes with a Soxhlet device or by boiling them in hot solvents to remove compounds that can catalyze aldehyde pheromone degradation. These prospective lures with then be loaded with the now known 4-component pheromone blend and their by quality and longevity testing will start in the laboratory by comparison with filter paper disks loaded with gland extract or the 4-component pheromone blend as positive controls.
