Blueberry was firstly domesticated almost 100 years ago. In the past century, the cultivated blueberries have gradually owned some desirable characteristics by selection. Field observations on blueberry revealed differences in insect selection preference exhibited between cultivated and wild highbush blueberries. However, little is known about the link between insect selection and domestication. There are a number of pests that can infect blueberries, and the brown marmorated stink bug (BMSB) is a potential serious pest for them. Some studies have focused on the blueberries feeding injury caused by BMSB, few works have studied the response of the blueberry plant to this pest, so little is known about influence of BMSB infestation on blueberry secondary metabolites, especially anthocyanin and phenolics accumulation. In this research, cultivated and wild highbush blueberries in New Jersey were analyzed comparatively to determine their quality attributes including pH, total soluble solids and individual weight, as well as their content of anthocyanin and phenolics. Samples were collected from 8 different locations to determine the interaction between domestication and location. Result showed that cultivated highbush blueberry had bigger fruit weight and higher pH value than wild blueberries, while wild blueberries were with higher anthocyanin and phenolic content. The growing location also affected pH and phenolic content of blueberry. The influence of BMSB infestation on highbush blueberry sugar, anthocyanin and phenolic accumulation was also determined in this experiment. Blueberries provided by the Marucci Blueberry and Cranberry Research and Extension Center in New Jersey were either mechanically damaged or infected by 0, 2, 5 or 10 adult or nymph BMSB and were collected at select time points from 3 different plots. UV-Vis spectrophotometry was applied for anthocyanins and phenolics quantitative analysis. The HPLC chromatographs were recorded to determine compositional differences among samples. The results showed that when samples were compared at similar maturity degree, the 2 or 5 nymph BMSB infestation stimulated blueberries to produce more phenolic compounds, and modified the proportion of certain individual anthocyanins, with little effect on anthocyanin content and sugar profile.
