“…As noted above, populations of the brown marmorated stink bug are bivoltine or partially bivoltine throughout most of the species’ native [ 12 , 17 , 18 , 30 ] and invasive [ 11 , 23 , 28 , 29 , 33 , 34 , 35 , 36 , 37 ] geographic ranges, although in some colder regions only one generation per year is produced [ 19 , 25 , 30 , 56 , 57 ]. The results of the regular field sampling during the four consecutive years and the monitoring of several morphological, physiological, and demographic parameters clearly indicate that in the Sochi region, H. halys is at least partially bivoltine: the main period of mass oviposition (by the overwintered females) occurs in June–July; the second much shorter period of egg-laying (by females of the new, i.e., the first, generation) followed by a new peak in the abundance of early instar nymphs occurs in August ( Figure 2 ).…”
