The brown marmorated stink bug, Halyomorpha halys, is an invasive pest species, first detected in Italy in 2012. Only 2 years after this first detection, increasing damage was reported in fruit orchards in the Emilia Romagna region, the first invaded area, which is one of the most important regions for the Italian and European fruit production. In the present study, life table parameters of H. halys populations were investigated in Italy under typical temperate/Mediterranean climate conditions representative of southern Europe. Our findings indicate that in Italy H. halys has two generations/year and very high reproductive rates for both generations (R0 = 24.04 and 5.44 for the overwintering and summer generation, respectively). The huge growth rates explain why in 2015 a massive outbreak of H. halys was observed in Italy, and these rates confirm that the pest is a threat for agricultural production in southern Europe. The parameters obtained in this study are essential for the development and optimization of sustainable management strategies.

Abstract

The brown marmorated stink bug, Halyomorpha halys, is an invasive pest species, first detected in Italy in 2012. Only 2 years after this first detection, increasing damage was reported in fruit orchards in the Emilia Romagna region, the first invaded area, which is one of the most important regions for the Italian and European fruit production. In the present study, life table parameters of H. halys populations were investigated in Italy under typical temperate/Mediterranean climate conditions representative of southern Europe. Our findings indicate that in Italy H. halys has two generations/year and very high reproductive rates for both generations (R0 = 24.04 and 5.44 for the overwintering and summer generation, respectively). The huge growth rates explain why in 2015 a massive outbreak of H. halys was observed in Italy, and these rates confirm that the pest is a threat for agricultural production in southern Europe. The parameters obtained in this study are essential for the development and optimization of sustainable management strategies.
