Harmful Insects


Many damaging insects and diseases can be anticipated either because they have been previously identified as harmful or because of the  environmental conditions. TREE MEDIC uses preventative treatments that are best applied before damage to your trees and shrubs occur. Problem pests common pests in the Western NY region are as follows:



Leaf-feeding aphids are very damaging and but large populations cause leaf changes and stunting of shMore than 100 soybean aphids collect on the underside of a soybean leaf. Pest feeding can inhibit the plant's ability to make grain, or kill it outright.oots. Aphids also produce large quantities of a sticky exudation known as honeydew, which often turns black with the growth of a sooty mold fungus. Some aphid species inject a toxin into plants, which further distorts growth. Around western New York we find the highest abundant of aphids in our locust trees.





Gypsy Moth
The gypsy moth is one of the most notorious pests of hardwood trees in the Eastern United States. Since 198gypsy0, the gypsy moth has defoliated close to a million or more forested acres each year. In 1981, a record 12.9 million acres were defoliated. This is an area larger than Rhode Island, Massachusetts, and Connecticut combined.








Japanese Beetles
Adult Japanese beetles feed on broad-leaved trees and plants and can cause significant Japanese-Beetle-Picturedamage as they defoliate the plants. The grubs will also feed on a wide variety of plant roots, including ornamental trees and shrubs, garden and truck crops, and turf grasses. We usually find these feeding on linden and birch trees especially.









Scale is a problem with many trees. Scale insects suck sap from plants, robbing them of scaleessential nutrients. They develop a hardened shell to protect them after they latch on to the newly devolved tree branches of certain trees, especially magnolia trees. Scale may be one of the more difficult insects to control in our area and is always best to be treated for as early as possible before their hardened armor takes form later in the growing season.











Bronze Birch Borer
4544.birch_die_back_2The bronze birch borer is a serious secondary pest of white, paper, and cut-leaf weeping birches. This native flat headed borer will attack yellow, gray, and other species of birch. It has also been reported on beech. Bronze birch borer adults are slender, dark, iridescent, often greenish-bronze, beetles, 7-12 mm long . A fully grown larva is slightly longer than 12 mm, very slender, and has a flattened, enlarged area behind its head.

Galls are abnormal plant growth or swellings comprised of plant tissue. Galls are usually foGouty_Horned_Gall4und on foliage or twigs. These unusual deformities are caused by plant growth-regulating chemicals or stimuli produced by an insect or other arthropod pest species. The chemicals produced by these causal organisms interfere with normal plant cell growth.

Gall can cause leaves to drop prematurely, or distort them so that photosynthesis (the plant’s food-making process) is interrupted. Galls generally are aesthetically objectionable to homeowners who find them unattractive and fear that galls will cause damage to the health of their oak trees.
