DISTRIBUTION,BIOLOGY,KEYCHARACTERISTICS
DistributionofBMSBinMichiganBrownmarmoratedstinkbug(BMSB),Halyomorphahalys,isatree-lovingpestnativetoAsia.ItwasfirstdetectedintheU.S.mainlandinPennsylvaniain1996.By 2006, it was causingmajor damage to apple and peach crops in themid-Atlantic region. The first Michigan detection was in Berrien County in 2010,followed several years later by reports of suspected BMSB fruit damage.Nuisance reports fromseveral thousandMichigan residents asof Spring2016indicate that BMSB populations are well-established in the southern LowerPeninsula. All together BMSB has been reported in 55 Michigan Counties,includingtwocountiesintheUpperPeninsula.
KeyfeaturesforidentificationAdultBMSBhaveseveralkeyfeaturestohelp distinguish them from nativebrownstinkbugs(Fig.1).Adultsare½inch long by 5/8 inch wide, with abanded pattern along the margin oftheir abdomen and banding on theirantennae and legs; they also havesmooth shoulders rather than toothedlikesomeofournativespecies.Eggsaregreenish-white in color and laid in acluster of up to 28 eggs on a leaf of apreferred host. There are five nymphalstages.The firstnymphal stage isblackandred.Theotherfournymphalstagesarebrownliketheadult(Fig.2).
BiologyandlifecycleBMSB adults emerge from overwintering sites (e.g. woodlots, manmadestructures) in response to a day length of 13.5 hours, which is late April inMichigan(Table1).Egglayingbeginsafter135degreedays(DD=base57.2°F)have accumulated, around the end of May. Females lay clusters of up to 28greenish-white eggs on the undersides of leaves of preferred host plants, andbetween10-20eggclustersintheirlifetime.Feedinganddevelopmentcontinuethrough fivenymphal stagesbeforemolting into theadult stage in late JulyorearlyAugust.HighdensitiesofBMSBandthepotentialfordamagebecomemorelikelyat this time.Thesummergenerationcontinues to feedbeforemoving tooverwinteringsitesbeginninginearlySeptemberthroughNovember.Theadultproducesanattractant, calledanaggregationpheromone,whichattractsotheradultstothesamelocation.Thisiswhyclustersofadultscanbefoundgatheringonbuildings.OnegenerationisthoughttooccurinMichigan(Fig.2).
