Trap-based monitoring and citizen reports indicate that stink bug numbers increased substantially in 20. Since then it has been detected in a number of areas throughout Minnesota and reproducing populations have been confirmed in several areas of the Twin Cities. The first find of BMSB in Minnesota was in 2010. Large numbers will congregate and invade buildings in search of overwintering sites. Significant injury caused by brown marmorated stink bug in orchards can result in large economic losses.ĭue to unpleasant odor, large size, and sheer numbers, BMSB can be a nasty home invader as well. Most damaged fruit is sent off for processing. All damage done is superficial and the fruit is safe to eat, however not preferred by consumers. In apples, feeding by this insect creates cork-like dead spots that can become sunken and render the fruit unsuitable for market. Injury caused by feeding produces small necrotic areas on the outer surface of fruits and leaves. Possible target crops in Minnesota include: apple, grape, soybean and other vegetables commonly grown in private and community gardens.īrown marmorated stink bug prefers fruits as a food-source, but will feed on nearly all plant parts. Plants with fruits, buds, and pods in places such as orchards tend to attract this insect more often than plants without those reproductive structures. Plants located near overwintering sites are a common place to find adult insects early in the season. After emerging in spring, adults are found on almost any plant exposed to the sun. Brown marmorated stink bug tends to congregate on tall plants and trees rather than plants lower to the ground. It has been observed on hundreds of tree species in the Mid-Atlantic States but it is unclear what species will be preferred in Minnesota. Over 300 plant species in agricultural, horticultural, and natural settings are susceptible to attack. Brown marmorated stink bug (BMSB) has a wide range of host plants.
