摘要

Wood cockroaches in the genus Parcoblatta, comprising 12 species endemic to North America, are highly abundant in southeastern pine forests and represent an important prey of the endangered red-cockaded woodpecker, Picoides borealis. The broad wood cockroach, Parcoblatta lata, is among the largest and most abundant of the wood cockroaches, constituting >50% of the biomass of the woodpecker's diet (1). Because reproduction in red-cockaded woodpeckers is affected dramatically by seasonal and spatial changes in arthropod prey availability, monitoring P. lata populations could serve as a useful index of habitat suitability for woodpecker conservation and forest management efforts. Current efforts to assess habitat quality and prey availability entail exceptional investment in broad-scale monitoring with nonselective traps such as burlap bands on trees or cardboard, pitfall, and light traps. A synthetic sex pheromone of P. lata, a major prey, holds promise as an important economically and ecologically sound tool to monitor the quality and suitability of foraging habitats for red-cockaded woodpeckers. We describe here the identification, synthesis, and confirmation of the chemical structure of this pheromone.
