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 can feed on and cause damage to strawberries (Fragaria × ananassa Duch.). metabolic response of attacks studied. Brown bugs attacked strawberry fruit which had 18% lower total sugar content compared the control treatment. However, organic acid no significant difference among three treatments, with exception shikimic acid, highest fruit. Thirty-one phenolic compounds were identified. Results showed a strong effect secondary metabolites due H. attacks. Halyomorpha treatment 27% higher analyzed indirect significantly increased ellagic derivatives (33.1% 37% higher), hydroxycinnamic acids (22.3% higher) anthocyanins’ (39% contents. Fruit by also catechin epicatechin than treatments. This influence plant’s metabolism, this improved our understanding how plant reacts very pest. halys-infested are not suitable for commercial production, production off-flavors.
