Research programs to date in British Columbia on the biology, damage and control of the white pine weevil, Pissodes strobi (Peck), a pest of spruce, Picea spp. and pine, Pinus spp., are reviewed. Significant progress has been made in the areas of genetic resistance, silvicultural and chemical control. An integrated pest management (IPM) system is formulated which combines silviculture-driven and resistance-driven tactics. The system relies on accurate hazard rating of plantation sites and requires continuous monitoring of attack levels and the forecasting of plantation productivity under various IPM tactics through the use of a decision support system. Research needs which would increase effectiveness of the IPM system are reviewed and organized in the context of the plantation productivity cycle.

White Pine Weevil

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.

Analysis of relevant data for the last 11 years improved the precision of zoning for white pine vulnerability to blister rust in Quebec. The validity of the existing approach for the area under study was confirmed. White pine located in zones 1 and 2 usually indicated less than 15% stem infections by the blister rust. Distribution of the white pine weevil damage in the zones is presented. Key words: Pinus strobus L., Cronartium ribicola J.C. Fisher, Pissodes strobi Peck, blister rust vulnerability.

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

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.
