Female Sex Attractant for Survey Trapping European Pine Shoot Moth

A “sticky” trap, utilizing female sex pheromone as bait, was developed for capturing males of Rhyacionia buoliana (Schiffermuller). The trap was successful for detection surveys, particularly in areas having low moth populations. The duration of the bait’s attractiveness was extended threefold by dissolving polyethylene glycol-600-disparate in methylene chloride extracts containing the sex attractant. Baits could be used up to 2 weeks in a cool, damp area such as western washington before recharging was necessary. Males responded to the female pheromone over distances of at least 85-90 m.
