Abstract:: The mountain pine beetle has impacted over 5 million hectares of pine forests in the Rocky Mountains region in the United States. Although some beetle-killed stands are available for salvage harvesting, there are many uncertainties in harvesting beetle-killed stands including safety, costs, recoverable products and their values. These uncertainties impose...

Abstract:: Populations of Dendroctonus ponderosae Hopkins from three pine hosts, Pinus ponderosa Laws., P. contorta Dougl. and P. monticola Dougl., were sampled with regard to their acoustic signals, the morphology of their stridulatory apparatus and some aspects of their emergence behavior. Comparisons of these characteristics were made between samples from different...
