Freshly planted red pine (Pinus resinosa Ait.) seedlings are vulnerable to injury by several agents. White grubs -- the larvae of May beetles (Phyllophaga spp.) -- are among these agents and sometimes must be controlled in areas scheduled for pine planting. A study was begun in 1967 to evaluate the effectiveness of applying three levels of aldrin for controlling white grubs in the Upper Peninsula of Michigan. After two years white grubs were satisfactorily suppressed by the three treatments tested (Fowler and Wilson 1971a). Reported here is a continuation of that study for five years following planting. We wanted to learn the effect of the aldrin treatments on the subsequent growth and survival of young red pine trees and to what extent white grubs and other agents injured or killed the red pine during the five years of treatment.
