Summary

  1. An EF 3 tornado developed a 63-km route by way of city and forested spots of western Massachusetts, U.S.A., on 1 June 2011.
  2. We collected ash, birch, maple, oak and pine logs from the tornado blowdown, after for every yr, about a 3-yr period and break up these into firewood sized items. Firewood was then positioned into rearing barrels and insects have been collected for 1 year.
  3. An estimated 38 121 beetles from forty two species of Buprestidae, Cerambycidae and Curculionidae: Scolytinae have been reared from firewood about the 3-yr period. The most abundant species collected involved Hylesinus aculeatus Say (85% of complete), Xyleborinus attenuatus (Blandford) (3.9%) and Monarthrum mali (Fitch) (3.6%).
  4. The major abundance of insects was found from ash in 2012 and 2014, and from maple in 2013. Species richness was best in oak in 2012 and 2013, and in birch and pine in 2014.
  5. 4 species of exotic xyleborines [Cyclorhipidion pelliculosum (Eichhoff), X. attenuatus, Xyleborinus saxesenii and Xylosandrus germanus (Bladford)] have been reared out of each firewood genus and accounted for a massive proportion of the Scolytinae captured.
  6. Probable new host associations incorporate the Cerambycidae Astylopsis macula (Say) in pink pine, the Scolytinae Gnathotrichus materiarius (Fitch) in hardwoods, and M. mali, X. attenuatus and X. saxesenii in ash.
  7. Firewood harvested from a massive scale disturbance in northeastern hardwood forests produced massive numbers of insects, even 3 years after the disturbance.
