  • The Stink Bug

  • Description

    Adults are approximately 17 mm long (25 mm = one inch) and are shades of brown on both the upper and lower body surfaces (Fig. 1).

  • It is known to be established in Pennsylvania, New Jersey, and Oregon

  • The eggs are elliptical (1.6 x 1.3 mm), light yellow to yellow-red with minute spines forming fine lines. They are attached, side-by-side, to the underside of leaves in masses of 20 to 30 eggs

  • The Brown Marmorated Stink Bug has a "shield" shaped body that is characteristic of all stink bugs.

  • Since 2000, the Brown Marmorated Stink Bug has been confirmed in several Mid-Atlantic States and in Oregon and California.

  • The Brown marmorated stinkbug is native to Asia

  • Hosts include maple, serviceberry, birch, butterfly bush, pepper, pecan, catalpa, hackberry, redbud, citrus, dogwood, cucumber, fig, sunflower, honeysuckle, tomato, apple, plum, pear, rose, lilac, linden, viburnum and grape.

  • The bug is indigenous to Asia and is considered an agricultural pest in Japan. The insects have been found in trees and in houses, where they produce a pungent, malodorous chemical.


  • The insect can be an agricultural pest, threatening apples, pears, peaches, figs, mulberries, citrus, persimmon and soybeans. It was found in Allentown, PA in October, 2001.

  • It shows 6 last or 5th instar nymphs, you can also see feeding damage on the leaf. There is also one last instar or 5th instar of another stink bug, Acrosternum hilare, or the green stink bug.

  • a polyphagous pest species and we can expect similar damage and eventually the brown marmorated stink bug will also have a similar distribution (found throughout southern Canada and US). Photo Taken in August.


  • they seek overwintering sites in households in the fall and re-emerge in the spring, which makes them a nuisance to homeowners

  • First reported in Lehigh County in September 1998, these exotic stinkbugs are now officially reported in 26 Pennsylvania counties

  • They can find their way through cracks around windows, doors, siding, utility pipes

  • Behind chimneys and underneath wood fascia and other openings should be sealed with silicone or silicone-latex caulk.

  • Life CycleAdults over-winter in structures and protected sites; they emerge in April to mate.1 generation in PA, up to 5 in S. China!Fall temperatures chase adults indoors.,8,Life Cycle
