20.500.12556/RUL-136640 Brown marmorated stink bug (Halyomorpha halys Stål.) attack induces a metabolic response in strawberry (Fragaria × ananassa Duch.) fruit The polyphagous brown marmorated stink bug (Halyomorpha halys Stål.) is an important pest in many countries. Recently it was noticed that it can feed on and cause damage to strawberries (Fragaria × ananassa Duch.). The metabolic response of strawberries to brown marmorated stink bug attacks was studied. Brown marmorated stink bugs attacked strawberry fruit which had 18% lower total sugar content compared to that of the control treatment. However, organic acid content had no significant difference among the three treatments, with the exception of shikimic acid, which had the highest content in the attacked fruit. Thirty-one phenolic compounds were identified. Results showed a strong effect on secondary metabolites due to H. halys attacks. Halyomorpha halys treatment had 27% higher total analyzed phenolic content compared to the indirect Halyomorpha halys treatment. The brown marmorated stink bug significantly increased total ellagic acid derivatives (33.1% to 37% higher), hydroxycinnamic acids (22.3% higher) and anthocyanins’ (39% higher) contents. Fruit attacked by Halyomorpha halys also had higher catechin and epicatechin content than that of the control treatments. This pest had a significant influence on the plant’s secondary metabolism, and this improved our understanding of how a strawberry plant reacts to the attacks of this very important pest. H. halys-infested fruit are not suitable for commercial production, due to the production of off-flavors. anthocyanins ellagic acid derivatives hydroxycinnamic acids strawberry total sugars total organic acids antocianini derivati elagične kisline hidroksicimetne kisline jagode sladkorji organske kisline Halyomorpha halys Stål.
