Abstract:The pine tortoise scale, Lecanium Numismaticum Pettit and McD., has recently caused serious injury to plantings of Jack pine and Scotch pine in the sandhill region of Nebraska.
An application of a commercial white oil emulsion used at 2% to 3% strength during the first two weeks of July, gave excellent control of the insect without injury to the trees.
