Toxicity of Pine Monoterpenes to Mountain Pine Beetle

open access: yesScientific Reports, 2017
AbstractThe mountain pine beetle (Dendroctonus ponderosae; MPB) is an eruptive bark beetle species affecting pine forests of western North America. MPB are exposed to volatile monoterpenes, which are important host defense chemicals. We assessed the toxicity of the ten most abundant monoterpenes of lodgepole pine (Pinus contorta), a major host in the ...
