Abstract
Computer-monitored flight mills with tethered emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), adults to measure flight speed, duration, and periodicity showed tethered beetles flew up to 5.2 km in two days at flight speed of at least 1.5 m/sec (3.5 mph). Females fly twice as far as males (P < 0.002), and mated females fly twice as far as unmated females (P < 0.0001). The discovery that mated females fly longer, further, and faster than either males or unmated females suggests that females are programmed to make a post-teneral dispersal flight.
