Studies on the olfactory behavior of the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins

Creator:: Jantz, Orlo Kenneth
Abstract:: Behavioral responses exhibited by the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, to various attractant sources were investigated under both laboratory and field conditions. Tests were designed to observe olfactory responses. Results were correlated and compared with collections from sampling nets and with emergence patterns. Field data were collected during the flight...

Certain biotic factors influencing the invasion and survival of the Douglas-fir beetle Dendroctonus pseudotsugae Hopkins (Coleoptera : scolytidae) in fallen trees

Creator:: Hendrickson, William Henry
Abstract:: Factors considered were phloem moisture, sour-phloem (which may be furthered by the presence of ample phloem moisture), oleoresin of the host, and the presence of unmated female beetles in suitable host material. Levels of phloem moisture present in variously prepared logs in the field ranged from about 100 to upwards...

Geographic factors as retardants to the development of Alaska's mineral industries

Creator:: Francis, Karl Earvil
Abstract:: The various elements of physical geography are commonly entertained as factors retarding the mineral industries of Alaska. It has been shown by numerous writers that the mineral industries of Alaska are, indeed, in a difficult situation. Only the petroleum industry and sand and gravel for construction are of much significance...
