Cranberry (Vaccinium macrocarpon) Is a Marginal Host for Brown Marmorated Stink Bug.

The brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a well-documented pest of agricultural crops across the globe. However, not all crops are suitable hosts for H. halys, and it is necessary to proactively document the susceptibility of economically important specialty crops, such as cranberry (Vaccinium macrocarpon; Ericaceae), a native fruit crop that contributes millions of dollars to the North American economy. In this study, we tested whether cranberry is a suitable host for H. halys by measuring the development and feeding injury inflicted by H. halys on cranberry fruit and foliage. We found that H. halys nymphs cannot successfully develop on cranberry fruit or foliage alone, but that the fruit are susceptible to adult feeding. On the basis of these findings, cranberry does not seem to be a suitable host to support nymph development, but adult feeding could negatively impact fruit quality. Future research should consider the impacts of adult feeding on fruit quality and how adult abundance in and near agricultural crops might change the risk profile of this pest.
