AbstractFeeding preferences of the white pine weevil, Pissodes strobi (Peck), for resistant or susceptible Sitka spruce, Picea sitchensis (Bong) Carr., were investigated using three types of laboratory bioassay. In paired-twig bioassays, fall weevils were significantly deterred from feeding up to 80% by resistant clones from four British Columbia provenances: Green Timbers, Cedarvale, Haney, and Big Qualicum. Females showed greater discrimination than males. Spring weevils were deterred from feeding by clones from the Green Timbers and Big Qualicum provenances by up to 60%. Fall males were more consistently deterred than spring males, suggesting that some host selection occurs in the fall. Females were significantly deterred from ovipositing on twigs from one clone from Big Qualicum, and stimulated by clones from Cedarvale when given a choice. Given no choice, however, they were significantly deterred from ovipositing, but not feeding by several resistant clones. In agar-disc bioassays, spring weevils were significantly deterred from feeding by bark from the provenances of Cedarvale and Big Qualicum by up to 86%. Trees from the provenances of Big Qualicum and Green Timbers caused the most consistent feeding or oviposition deterrency and may rely on this in part as a resistance mechanism. Because not all resistant clones and provenances were deterrent, we hypothesize that these trees may employ other resistance mechanisms which could be incorporated along with feeding and oviposition deterrency into breeding for resistance.

White Pine Weevil

This paper presents the results of quantitative studies designed to determine, under field conditions, the influence of weather on the activity and development of adults and larvae of the white pine weevil, Pissodes strobi (Peck). The investigation forms part of a general program to determine the physical and biological requirements of the insect, with the ultimate objective of assessing the role of the environmental complex in limiting weevil development and survival to particular stand conditions. The problem arose when it became apparent that this information was pertinent to studies designed to determine the effectiveness of applied silviculture in the control of the insect. In addition, it provided the opportunity of assessing the effectiveness of applying quantitative bioclimatic methods in the field.

White Pine Weevil

The lodgepole terminal weevil, Pissodes terminalis Hopping, is the only member of its genus that consistently oviposits in the expanding terminal shoots of its hosts (Stark and Wood 1964). The white pine weevil, Pissodes strobi (Peck), oviposits in the year old shoot of spruce and pine (Wallace and Sullivan 1985) and other Pissodes species have their oviposition sites on boles, root collars, and slash (Furniss and Carolin 1977). In southern British Columbia, P. terminalis is primarily univoltine although adults may live and oviposit for 2 or more years. Although its life cycle is closely synchronized with terminal phenology, its life history is extremely variable (Cameron and Stark 1989). Adults are active in late spring to early summer, when they can be found feeding on the tissues of the developing terminal shoot and foliage. Soon after this maturation feeding, mating occurs, and oviposition punctures are excavated in the bark of the new terminal. Usually a single egg is deposited into each puncture (Drouin et al. 1963; Stark and Wood 1964; Maclauchlan 1992).

White Pine Weevil

Past infestations of the white pine weevil, Pissodes strobi (Peck), were reconstructed by examining standing and felled trees in naturally regenerated interior spruce stands in the McGregor Model Forest in northern B.C. Infestations were common in both the Sub-Boreal Spruce (SBS), wet cool (SBSwk) and very wet cool (SBSvk) biogeoclimatic subzones, demonstrating that frequent weeviling is a natural event that predates human intervention. Approximately one-third of all stem defects in 32 felled trees were verified as caused by the weevil. In the SBSwk and SBSvk 56.3% and 81.3% of felled trees contained weevil-caused defects, with 1.9 and 2.1 defects per tree, respectively. Trees in the SBSvk had significantly more weevil attacks high on the bole than trees in the SBSwk.

White pine weevil (Pissodes strobi Peck) damage was evaluated in one white pine (Pinus strobus L.) and four jack pine(Pinus banksiana Lamb) half-sib family test sites to determine the role of tree genotype in resistance to the weevil. Halfsibfamily explained a significant proportion of the variation in weevil attack at all sites. Estimates of family (0.16-0.54)and individual (0.09-0.24) heritabilities of jack pine resistance to white pine weevil were moderate. Estimates of family(0.37) and individual (0.22) heritability of resistance of white pine to the weevil were also moderate when the percentageof test trees damaged by the weevil was relatively low, but were insignificant four years later when more than three-quartersof trees were damaged. Significant positive correlations between mean tree height and mean incidence of trees damagedby the weevil were observed for four of seven site-years but relationships were weak, suggesting that any cost, withrespect to height growth, to breeding weevil resistant trees may be small.Key words: Pinus, Pissodes strobi, trade-offs, tree improvement, tree resistance, white pine weevil.

Cortical resin acids were analyzed both quantitatively and qualitatively among 10 provenances and 11 genotypes of Sitka spruce, Picea sitchensis Bong (Carr.), putatively resistant to the white pine weevil, Pissodes strobi (Peck), and compared with susceptible trees. Trees in 5 of the 11 resistant genotypes had significantly greater amounts of cortical resin acid than susceptible trees. Of seven individual acids analyzed, pimaric, isopimaric, levopimaric, dehydroabietic, abietic, and neoabietic acid, but not palustric acid, were found in significantly greater amounts in trees from resistant than susceptible provenances. Eighteen percent of the variation in resin acid content could be accounted for by variation in the capacity of cortical resin ducts, indicating that the other 82% of variation is a result of differences in resin acid concentration in the resin. Trees with very high resin acid levels may have a greater capacity for resinosis than susceptible trees, may deter feeding, or may produce resin that is toxic to eggs and larvae. Canonical discriminant analysis revealed that several resistant clones, particularly two from the Kitwanga provenance, could be distinguished from others on the basis of their resin acid profiles. Because it separated trees on the basis of genotype, but not according to degree of resistance, canonical discriminant analysis may be more useful in "chemotyping" trees than in screening for resistance.
