The objective of this investigation was to determine if external factors such as phototaxis and geotaxis determine oviposition site location by reproductively active female white pine weevils, Pissodes strobi (Peck), on intact trees or cut treetops.

The white pine weevil’s [Pissodes strobi (Peck)] choice of bark tissue for ovarian maturation feeding was determined. In addition, the thicknesses of primary cortex tissue were determined to ascertain if primary cortex thickness was positively corr

Available information on the interaction between Sitka spruce weevil, Pissodes strobi (Peck), and its host Sitka spruce, Picea sitchensis (Bong) Carr., is examined. Based on a theoretical consideration of this information, a new mechanism is proposed

Associations between the density and distribution of cortical resin canals of host trees and their resistance against insects have been the subject of many studies (Stroh and Gerhold 1965; Wilkinson 1983; Tomlin and Borden 1994a, 1994b). None, howeve

To distinguish between western (Pinus monticola) and eastern (P. strobus) white pines, foliage, buds, and cones were examined and foliar terpenes were extracted and analyzed from representative samples. Needles of P. monticola were heavier, wider (>0
