A new study finds that brown marmorated stink bug (Halyomorpha halys) doesn’t respond to its own aggregation pheromone until spring arrives—specifically, when daylight reaches 13.5 hours. As a result, common monitoring traps that use the insect’s pheromone to attract it prove unreliable during its overwintering period. (Photo credit: Rob Morrison, Ph.D.)
