The brown marmorated stink bug, (Stål), is an invasive species from Asia. This polyphagous, stink bug species has posed a serious production challenge in several crop species in the areas where established. The insect has spread to all the mainland states in the U.S. in about one and half decades after its first detection in Pennsylvania. The types of crops reported to have been infested by this stink bug have increased with its spread to new geographic locations. In this study, we report the first evidence of infestation in almond fruit in California. In Stanislaus County, an adult brown marmorated stink bug in an almond orchard was first observed in May 2017. The stink bug feeding on almond fruits caused excessive gumming to the developing fruits, and damage to the kernels along with typical necrotic feeding signs on the shell (endocarp) and hull (exocarp and pericarp) of the fruit at harvest. The infestation and damage by on almond warrants further research to develop Integrated Pest Management (IPM) strategies for this pest.
棕色入侵臭虫（Stål）是一种来自亚洲的入侵物种。这种多食性臭虫物种在其已定居的地区对多种作物品种构成了严重的生产挑战。该昆虫在宾夕法尼亚州首次被发现后的大约十五年半时间里，已扩散到美国所有的大陆州。随着这种臭虫扩散到新的地理位置，报告称受其侵害的作物种类也有所增加。在本研究中，我们报告了加利福尼亚州杏仁果实受其侵害的首个证据。在斯坦尼斯劳斯县，2017年5月首次在一个杏仁果园中观察到一只成年棕色入侵臭虫。以杏仁果实为食的臭虫导致发育中的果实过度流胶，并对果仁造成损害，同时在收获时果实的壳（内果皮）和果壳（外果皮和中果皮）上出现典型的坏死取食迹象。棕色入侵臭虫对杏仁的侵害和损害值得进一步研究，以制定针对这种害虫的综合虫害管理（IPM）策略。
