The Brown Marmorated Stink Bug is a pest to a large variety of fruit-bearing trees and plants. Accidentally imported from Asia, the Brown Marmorated Stink Bug made its way to North America's east coast and has been establishing populations there and beyond ever since.
They are known to damage fruit in appearance (not flavor or by adding toxins), rendering the fruit less likely to see at market. The Brown Marmorated Stink Bug uses its proboscis to poke a hole through the skin of a piece of fruit (still growing on the tree) and it sucks out the fruit's juices. The depletion of juice and penetration to the skin of the fruit results in creating a dimple, which continues to deform the fruit as it grows to a picking age. A series of these bites can cause the fruit to look quite deformed and renders it useless to try and sell.
Their color makes them effective camouflaged insects. Both the nymphs and adults feed off of the leaves or on orchard tree's fruit. The nymph looks very unlike the adult. It is shaped more like a ladybug and is red and black with distinctive black bands running down its back.
Members of the Stink Bug family are capable of emitting a foul-smelling odor that the insect produces when threatened, disturbed, or touched. This smelly chemical is produced by specialized stink glands in both the male and female. The Brown Marmorated Stink Bug may find its way into buildings or homes in the winter, seeking warmer temperatures that allow it to hibernate, not freeze. They can and do emit their odorous secretions inside, making them a nuisance indoors as well as outdoors.
