The status of brown marmorated stink bug, Halyomorpha halys, in Bucharest area

Halyomorpha halys was first time discovered in Bucharest in September 2014, in the Botanical Garden of Bucharest. The authors of the first report state that the entrance in the country could happen at least 1-2 years before, due to the fact that individuals of Halyomorpha halys were found in a range of several kilometres. Our observations in Bucharest area in 2016 show an alarming exponential spread of the H. halys, mainly in the USAMV Bucharest corn testing fields, goji testing fields, jujube experimental field and edible roses testing fields. Halyomorpha halys and Nezara viridula were always observed in cohabitation and they produced crop losses of 100% to goji , starting with the month of august and major quality depreciation in the corn field
