Brown Marmorated Stink Bug
Brown Marmorated Stink Bug
The Brown Marmorated Stink Bug comes from Asia. It was first found in Pennsylvania in the fall of 1996, but was not fully recognized or identified until 2001.
Here in the United States, Brown Marmorated Stink Bugs become active around April. Their mating season beings right after in May and continues through August. Eggs are laid underneath leaves in clusters of 20 to 30 eggs. In just four to five days after being deposited, the nymph will go through five instars. Brown Marmorated Stink Bugs create just one generation per year.
How to Identify a Stink Bug
Nymphs body size ranges from 2mm-12mm during all five stages of instar. Their bodies are yellowish red and they have red eyes. The color of their body changes as they grow to adult.
As an adult, the Brown Marmorated Stink Bug grows to be about 12-17 mm in length. Their color marking is marbled brown and white and the outer bands are white and broad. They do have wings, but they do not completely cover their abdominal region, which leaves the alternating dark and pale colors visible. The shape of their body is almost triangular.
Why is The Stink Bug Considered a Pest?
Even though the Brown Marmorated Stink Bug is fairly new to the United States, they have since become an infestation here. Although they are harmless to humans, they do wreck havoc on your plant, fruit and vegetable gardens.
Brown Marmorated Stink bugs, as nymphs, feed on leaves. As they grow, they begin to feed on ornamental plants and trees such as- the Crab Apple, American Holly, Norway Maple, and more. Fruits they enjoy to feed on are raspberries, pears, and peaches. Vegetable wise, they feed on asparagus, and string beans.
Another reason Stink Bugs are considered a pest, is in their name. They stink. Especially when smashed. The foul odor they excrete comes from three different sections of their body- one on top and two from their abdomen. Beware because their odor is pungent and it lingers.
