White grubs, the larvae of May beetles (Phyllophaga spp.), feed on the roots of newly planted red pine (Pinus resinosa Ait.) seedlings in the Lake States region. A 1/2 or 1% solution of aldrin insecticide is recommended to control these grubs (Shenefelt and Benjamin 195; Speers and Schmiege 1961). Treatments of white grubs in Michigan using a 1% solution dispersed from the planting machine (standard method) have given erratic control and therefore reevaluation appeared necessary. We decided to retest the standard application method and to test two new methods.
