A few years after the first appearance in Italy in 2012, the Asian Brown Marmorated Stink Bug (BMSB) Halyomorpha halys (Heteroptera, Pentatomidae) became a serious pest of fruit crops in Northern regions, causing up to 80% damage in some areas of Emilia Romagna pear orchards in 2015. In this Region the network between the University and the Plant Protection Services of Modena and Reggio Emilia allowed to act sinergically in carrying out a multidisciplinary applied research project on this invasive pest. A citizen science survey allowed to obtain the updated BMSB spread map and the DNA analysis of collected samples showed that Italy has the highest haplotype diversity beyond native Asian population, indicating multiple invasion pathways. A detailed life table study showed that BMSB performs two generations/year with overlapping adult and juvenile stages during summer, and has a remarkable invasive potential due to its high rate of increase and specific behavioural features. A three years monitoring program in orchards and adjacent uncultivated areas assessed various aspects of the insect biology and the applicability of active and passive monitoring techniques to estimate the presence, abundance, and seasonality of BMSB populations in the field. Presently, crop management relies on insecticides, however different IPM approaches are being evaluated, that include a survey on native natural antagonists potential, a behavior-based management of orchards boards and hedges and the use of exclusion netting.
