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...
