Abstract
In the absence of secondary attraction, 2 species of Scolytidae,
Ips latidens (LeConte) and
Hylastes gracilis LeConte, showed significant preference while in flight for high-girdled over non-girdled lodgepole pines,
Pinus contorta var.
latifolia Engelmann. In contrast, beetles in 2 genera of Elateridae,
Ampedus and
Ctenicera , showed significant preference for non-girdled over high-girdled lodgepole pines. Beetles in 12 other families, as well as other scolytids and elaterids, did not show any significant preference or aversion to high-girdled trees. This is the first clear demonstration of primary attraction for a North American
Ips species and the second for an
Hylastes species.
