. Cooperative economic insect report. Beneficial insects; Insect pests. - 1028 Plantations Damaged By Many Insects The European pine shoot moth, Rhyacionia huoliana (Schiff.), continued to damage valu- able plantings of red and Scotch pines in the western two-thirds of the Northeastern States. Another shoot moth, Eucosma gloriola Hein., caused substantial twig killing of red, Scotch, white, and Austrian pines in several counties in Pennsylvania. The Nan- tucket pine moth, R. frustrana (Comst.), se- verely attacked many young loblolly pine plantations along the eastern shore of Maryland. Scattered infestations were reported elsewhere in the eastern part of the State. The pine engraver, /ps fini (Say), continued its depredations throughout the Northeast. Increasing populations were found in west- ern New York. If rainfall deficiencies con- tinue, more serious trouble may develop. The balsam gall midge, Dasyneura balsamicola (Lint.), troubled Christmas tree growers in Vermont, and the pales weevil, Hylobius â pales (Hbst.), severely damaged Scotch and white pine Christmas tree plantings in Pennsylvania and New York. Heavy attacks by the pine root-collar weevil, H. radicis Buch., occurred in red and Scotch pine plantations in Warren, Saratoga, and Lewis Counties, New York, and almost wiped out a Scotch pine Christmas tree plantation at Shelton, Connecticut. Conspicuous browning of pitch pine and Virginia pine resulted from feeding by the pine needle miner, Exoteleia pinifoKella (), in Kent and Newcastle Counties, Delaware; southern New Jersey; and, the Myles Standish State Park, Massachusetts. The eastern spruce gall , Chermes abietis L., was active in New York, Pennsylvania, Maryland, and Maine. The Cooley spruce gall aphid, C. cooleyi Gill., was abundant on introduced Colorado blue spruce, Engelmann spruce, and Douglas-fir throughout New York; 50 percent of the spruce twigs were distorted in some areas.
