This is a database on pest management from Cornell - my old alma matter. It's a tool for identification alerting you to many potential problems but certainly not all. If you suspect a problem bring a sample in and we will help you identify it and discuss possible controls. We will recommend an organic approach to control these pests. The letter within the ( ) stand for the stage of development of the pest. A=adult. c=crawler. E=egg. i=immature. l=larva. n=nymph m=moth. Dormant Season, March to early April: Before deciduous plants leaf out. Pest management should be accomplished at this time of the year by spraying dormant oils on the plants when temperatures are above 50 degrees Arborvitae: Fletcher scale(i)spruce spider mite(e) Azalea: azalea bark scale(a) Bittersweet: euonymus scale(a) Crabapple: European red mite(e) Deciduous plants: aphids(e) Douglas fir: cooley spruce gall adelgid(i) Euonymous: euonymus scale(a) Flowering fruit trees: lecanium scales(a) Hemlock: wooly adelgid(e)hemlock eriophyid mite(ia)elongated hemlock scale(a)spruce spider mite(e) Holly: southern red mite(e)Honneylocust: lecanium scales(a) Juniper: juniper scale(ae) spruce spider mite(e) Lilac: oystershell scale(e) Magnolia: magnolia scale(n) Maple: lecanium scale(a)maple gall mites(a) Oak:golden oak scale(a) Pachysandra: euonymus scale(a) Pine: pine bark adelgid(i) pine needle scale(e) spruce spider mite(e) Spruce: eastern spruce gall adelgid(i) spruce bud scale(i)spruce spider mite(e) White pine: white pine aphid(e) Yew: fletcher scale(n) taxus mealybug(i) cottony taxus scale(i) Early to mid April: Delayed dormant spray.
