"The bark beetle antiaggregative pheromones, verbenone and ipsdienol, were tested in protecting heat-injured lodgepole pine (Pinus contorta Dougl. ex Loud.) from mountain pine beetle (Dendroctonus ponderosae Hopkins) infestation in the Sawtooth National Recreation Area in central Idaho. Peat moss was placed around 70 percent of the basal circumference of lodgepole pines. When the peat moss was ignited, it simulated the smoldering of natural duff, generating temperatures that killed the cambium. The four treatments tested were uninjured tree, heat-injured tree, heat-injured tree treated with verbenone, and heat-injured tree treated with verbenone plus ipsdienol. Treatments were replicated 20 times. Mountain pine beetles were attracted into treatment blocks by placing mountain pine beetle tree baits on metal posts 3 to 5 meters from treated trees. Fisher's Exact Test showed that treatment and beetle infestation were not independent (P

This publication supplements Wood & Bright's 1992 catalogue of the world's Scolytidae and Platypodidae (bark beetles), updating the taxonomy of these two families to nearly the end of 1995 and including all known literature references to the end of 1994 (plus references to articles missed in the earlier bibliography). References which provide new information on taxonomy, host plants, or biology of a species are also included. The format of the supplement closely follows that of the 1992 catalogue. Each genus & species is listed with its page number from that catalogue; additional information on figures, distribution, hosts, and references to other subject areas are given. The publication also includes lists of host plants, arranged by scientific name, and the beetles attacking them.
