Haack: Bark- and Wood-Infesting Insects Collected on Drummond Island 2020 THE GREAT LAKES ENTOMOLOGIST 73 Buprestidae, Cerambycidae, and Siricidae Collected in Baited Funnel Traps on Drummond Island, Chippewa County, Michigan Robert A. Haack USDA Forest Service, Northern Research Station, 3101 Technology Blvd., Suite F, Lansing, MI 48910 (e-mail: [email protected] (emeritus)) Abstract Trapping of bark- and wood-infesting insects in 2015 and 2016 at multiple locations on Drummond Island in northern Lake Huron, using baited multi-funnel traps, yielded 4 species of Buprestidae, 24 Cerambycidae, and 4 Siricidae. In 2015, all funnel traps were baited with the plant volatiles α-pinene, ethanol, and cis-3-hexenol, and were either black or green in color, and placed either at heights similar to the lower canopy of nearby trees (4-5 m) or at 1-2 m above groundline. In 2016, all traps were green, hung at 1-2 m above groundline, and baited with the cerambycid pheromones fuscumol acetate, monochamol, and syn-(2,3)-hexanediol. In 2015, 29 species of Buprestidae, Cerambycidae, and Siricidae were captured, compared with 9 cerambycids in 2016. The original target insect, emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive pest from Asia, was not trapped in either year.
