Emerald Ash BorerEmerald Ash Borer

In North America the borer is an invasive species, highly destructive to ash trees in its introduced range. The damage of this insect rivals that of Chestnut blight and Dutch Elm Disease. To put its damage in perspective the number of chestnuts killed by the Chestnut Blight was around 3.5 billion chestnut trees while there are 3.5 billion ash trees in Ohio alone. Dutch Elm Disease killed only a mere 200 million elm trees while EAB threatens 7.5 billion ash trees in the United States. The insect threatens the entire North American Fraxinus genus, while past invasive tree pests have only threatened a single species within a genus.

pineshoot

Pineshoot Beetle

The Common Pine Shoot Beetle is a serious foreign pest of pines, which attacks new shoots of pine trees, stunting the growth of the trees. The Pine Shoot Beetle also might attack stressed pine trees by breeding under the bark at the base of the trees. The beetles can cause a severe decline in the health of the trees, and possibly kill the trees when high populations exist.

gypsy-MothGypsy Moth

The gypsy moth is the most destructive forest insect pest to infest New Jersey’s forests. Repeated defoliation by the gypsy moth represents a serious threat to New Jersey woodland and shade tree resources.

The New Jersey Department of Agriculture promotes an integrated pest management approach, which encourages natural controls to reduce gypsy moth feeding and subsequent tree loss. However, when gypsy moth cycles are at a peak, natural controls have difficulty in preventing severe defoliation. In these special cases, the Department recommends aerial spray treatments on residential and recreational areas.

hemlock_woody_adelgid5Hemlock Woolly Adelgid

Adelgids are aphid-like insects. The hemlock woolly adelgid is a tiny exotic invasive species that gets its name from its woolly white appearance and because its host is the hemlock tree (Tsugae species). The hemlock woolly adelgid has a complex life cycle and produces two generations per year. Eggs are brownish-orange and wrapped in a white fluffy substance secreted by an adult female. Reddish-brown nymphs (or crawlers) hatch from the eggs and use their thread-like mouthpart to pierce a hemlock branch and suck sap from the branch. These nymphs go through four stages before becoming adults and also wrap themselves with a white, fuzzy covering. Adults are reddish-purple and some have two pairs of wings. The flying adults leave the hemlock in search of a secondary oriental spruce host (which does not occur in the United States). The wingless adults stay on the hemlock host and produce 50-300 eggs. Adults, as well as the nymphs, suck sap from young twigs on hemlock trees and cause the hemlock needles to dry out and drop. This defoliation can cause the hemlock tree to die in only a few years.

Asian Longhorn BeetleAsian Longhorn Beetle

While the Asian Longhorn Beetle (ALB) may appear threatening, it is harmless to humans and pets. The adult ALB is a distinctive-looking insect with the following unique characteristics

  • 1 to 1 ½ inches in length. Long antennae banded with black and white (longer than the insect’s body)
  • Shiny, jet black body with distinctive white spots
  • Six legs
  • May have blue feet

Adult beetles are most active during the summer and early fall. Throughout the summer, they can be seen on tree branches, walls, outdoor furniture, cars and sidewalks. If you see the beetle or any signs of infestation, you need to report it immediately.

You won’t see the beetle after the first frost until it emerges again in the summer. During the winter months, the beetle’s larvae tunnel deep into the trees they infest. Although you can’t spot it, you can still be a beetle buster by not moving firewood. Moving firewood can spread the beetle, its larvae and its eggs to healthy trees. So buy it locally and burn it locally, and don’t move firewood off of your property.
