  1. Introduced Beetles in the United States By Matthew Reitzel

  2. Asian Longhorned Beetle • The scientific name is Anoplophora glabripennis. • Native to China and Korea • First Found infestation in the United States was in New York in 1996 • Then found in Chicago in 1998

  3. Identification • The adult is over an inch in length • Coal black body with yellow or white spots • Long antennae with white bands

  4. Trees affected • Yellow-poplar • Willow • Elm • Maple • Horsechestnut • Ash • There are many more but these are just a few

  5. Egg laying • The female beetle chews a small hole into the cambium through the bark and lays a single egg that is about the size of a grain of rice right under the inner bark onto the surface of the wood. • The hole is filled up with digested wood which is know as frass. • One female beetle can lay about 35 eggs in their 42 day life cycle

  6. Larva • the incubation period is about 11 days • After they hatch they feed off of the cambium layer • After they shed their skin twice they start boring into the wood of the tree into the water transporting vessels deeper inside of the tree

  7. Detection of infestation • They only way of detection is by visual examination of the tree checking for sawdust or sap coming from slits left by the female

  8. Treatment • The only way to treat an infected tree is to cut down the infected tree. • Some places even chip up the trees and incinerate the chips.

  9. Japanese Beetle • Popillia japonica • First found in the United States in Philadelphia, PA in a nursery near Riverton, NJ in 1916 • It is believed that they came into the United States in a shipment of iris bulbs that came from Japan

  10. Identification • The adult beetles are about 3/8th of a inch long with a copper-brown color on their wings • They also have 5 small white tufts project from under the wing cover on each side and a 6th pair at the tip of the abdomen.

  11. Larva • The larva develop in the earth and as they are growing they eat the roots of various plants • They eat the roots of turf and grass to destroying some yards.

  12. Life Cycle • Adults emerge from the ground in late May or early June • They live about 30 to 45 days • Numbers start to decline in late July but can still be found as late as September

  13. Trees affected • They feed on almost any tree ranging from roses to poison ivy. • Odor and location in direct sun light seem to play an important role in plant selection

  14. Signs of Infestation • Skeleton looking appearance of the leaves • They start at the top of the plant working their way down eating all of the tissue between the veins.

  15. Treatment • Insecticides • Natural predators • Collecting beetles in traps • Plant selection

  16. Emerald Ash Borer • Agrilus planipennis • Discovered in Detroit Michigan in the summer of 2002. • The natural range is eastern Russia to northern China, Japan, and Korea

  17. Identification • Adults are dark metallic green about ½ inch in length and about a 1/16th of a inch wide • The larvae are creamy white and found under the bark

  18. Life Cycle • They are only present from mid May to late June • Life span is about 3 weeks • Eggs are laid soon after emerging. Each egg is laid by its self • One female can lay 60-90 eggs

  19. Larva • Spend the winter months inside the tree feeding in the cambium layer. • As they emerge out of the tree in early summer they leave a D shaped exit hole

  20. Damage done • The damage done to the tree is not done by the adult form but by the larva • The larva feeds on the inner bark of the tree disrupting the ability of nutrient and water transport. • The adults just eat the parts of the leaves

  21. Signs of Infestation • The first sign is the upper third starts to die back, next year the rest of the tree dies back which is followed by shoots growing below the dead trunk sections • They only attack ash trees

  22. Treatment • You can spray but it does not work 100% of the time • Any trees that if affected is cut down and disposed of • Also there is a program that replaces the open spaces made from the dead trees

  23. Why Care • We should care because if we do not these beetles will consume the entire country killing off almost every tree to the point where our landscape will become barren and dead trees everywhere.
