Abstract

A study was made of white pine weevil attack occurring on 266 one-tenth acre sample plots of white pine over 16 feet tall in New York. Tree data collected included measure of weevil damage to the main stem in relation to height, and frequency of weevil attack. Plot data included information pertaining to drainage, exposure, elevation, tree growth, tree distortion due to weeviling, silviculture, soil litter, soil characters, and root penetration. Analysis of the data showed that only soil mottling and hardpan were correlated with stand damage, and that there was significantly more weevil damage in stands where these factors occurred in a 3-foot soil profile. Also, there was a direct correlation between weevil attack on the main stem and tree height at time of attack. Frequency of attack reached a peak at the 10- to 20-foot height level and then declined as height increased.
