Diurnal and seasonal flight patterns of bark beetles (Coleoptera : Scolytidae) associated with Douglas-fir forests of western Oregon

Creator:: Daterman, Gary E.
Abstract:: The study was undertaken to determine the seasonal and diurnal flight patterns of scolytid beetles inhabiting a second growth forest of Douglas-fir (Pseudotsuga menziesii (Mirb.)Franco) in western Oregon. Air temperatures, relative humidity, light intensity, and wind velocities were recorded for evaluation of their influence on flight activity. The insects were...

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...
