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.
褐带扁股小蜂,又称亚洲玉米螟(Stål)(半翅目:五角枫科),是一种在全球范围内对农业作物造成严重危害的害虫。然而,并非所有作物都是褐带扁股小蜂的适宜宿主,因此有必要积极记录具有经济重要性的特种作物(如蔓越莓(Vaccinium macrocarpon;杜鹃花科),这是一种原产于北美的水果作物,为北美经济贡献了数百万美元)的易感性。在这项研究中,我们通过测量褐带扁股小蜂对蔓越莓果实和叶片造成的发育和取食损伤,来测试蔓越莓是否是褐带扁股小蜂的适宜宿主。我们发现,仅用蔓越莓果实或叶片不能使褐带扁股小蜂的若虫成功发育,但果实容易受到成虫取食。根据这些发现,蔓越莓似乎不是支持若虫发育的适宜宿主,但成虫取食可能会对果实质量产生负面影响。未来的研究应该考虑成虫取食对果实质量的影响,以及农业作物内和附近成虫数量的变化如何改变这种害虫的风险状况。
