US researchers identify stinkbug pheromones
USDA researchers have identified the aggregation pheromones of the brown marmorated stinkbug (Halyomorpha halys), which could lead to the development of traps and control technologies. The scientists synthesised two pheromones produced by adult male stinkbugs and used them in traps to attract males, females and nymphs. The pheromones were three times more effective when combined in one trap than when used individually. The study was conducted by scientists from the USDA Agricultural Research Service's Invasive Insect Biocontrol and Behavior Laboratory in Beltsville, Maryland. It has been published in the Journal of Natural Products. Another study published in the Journal of Economic Entomology found that one of the pheromones could be combined with another attractant and attracted more insects than either used alone. It could be used in commercial traps and lures throughout the growing season.
