Large Outdoor Cage Tests with Eastern White Pine Being Tested in Field Plots for White Pine Weevil Resistance

A study made by Connola and Wixson (1963) in New York from 1954 through 1958 on white pine weevil, Pissodes strobi (Peck), attack in 266 one-tenth acre sample plots of eastern white pine, Pinus strobus L. throughout the State showed that there was more weevil damage in the southern half of the State than in the northern half. Statistical analysis of the data showed that heavy weevil damage was significantly related to the presence of hardpan in the soil within 3 feet of the surface. Hardpan was prevalent in the heavy soils in the southern half of the State.
