Abstract:

This article is the first report in Idaho of 4 particular beetle species, which were encountered after the upper 25–25% of the canopy was removed from 30 ponderosa pines and 28 western white pines on the University of Idaho’s Experimental Forest. Volatiles that are released from the severed stems when the tops of trees are removed, a practice to increase the efficiency and economy of orchard cone harvesting, may attract insects to the treated trees. A total of 13,547 beetles representing 47 families were captured during two years (2003–2004) of study. The four beetle species never before reported in Idaho were Chrysobothris californica LeConte, Laricobius nigrinus Fender, Cimberis turbans (all three captured in only 2004), and Podapion gallicola Riley (captured both years). All nine pine gall weevils (P. gallicola) captured are reported to occur throughout the eastern United States and southeastern Canada. L. nigrinus, a predator of hemlock woolly adelgid, is being introduced in the eastern United States in a biological-control effort against the invasive forest pest. The Experimental Forest has a small component of western hemlock (Tsuga heterophylla). All seven specimens of L. nigrinus were captured in western white pine during the year after upper canopy removal of treatment trees.
