Brown Marmorated Stink Bug Arrives

It is official. The brown marmorated stink bug, Halyomorpha halys, has been identified in North Carolina. First detected about two weeks ago in the Winston-Salem area, there has been another report in the coastal plain region. Originally found in Allentown, Pennsylvania in 2001, it is now established in many states across the country especially along the east coast. It is an easy traveler in things like motor homes. There is a long list of hosts, both ornamental and agricultural from maple and birch to pecan, peach, apple and cucumber. Adults emerge from overwintering about April. All instars have deep red eyes. Early nymphs are red, then almost black, and finally brown in color as adults. They are typical stink bugs in most ways and damage fruit and foliage with their feeding (proboscis) and saliva. There is a single generation in northern states. To add to their annoyance, they like to overwinter in protected places such as structures. This is where you are most likely to first notice them.
