BROWN MARMORATED STINK BUG

BROWN MARMORATED STINK BUG
This is another new invasive species. The Brown Marmorated Stink Bug first appeared in 1998, and has spread slowly over the eastern half of the state. They are brown colored with streaks, and about 3/4ths inch in size. It is an agricultural pest in eastern Asia, and can also be a nuisance pest as it enters houses in the fall seeking a warm place to overwinter. It is most active in the spring and summer, however. This stink bug is a true bug, and attacks fruit trees, ornamentals, and soybeans. It can make the fruit unmarketable. When squashed or captured, it can release a very noticeable odor from its scent glands.

Life Cycle
During the summer, females attach about 20-30 eggs in two rows underneath leaves. They hatch later in the summer, and the nymphs go through five instars, growing from 1/10th to ½ inch in size. Some adults appear as early as mid-August, and by late September to early October they start their flights seeking overwintering locations. There is only one generation per year
