The invasive brown marmorated stink bug (BMSB), Halyomorpha halys Stål, and the southern green stink bugs (SGSBs), Nezara viridula L., are widely distributed in Europe, even if the date of introduction and the diet differ. Saliva of Hemipteran pests plays essential roles in the interaction between insects and their host plants. The salivary proteomes of several aphid species have been studied and found to differ according to the species, while no comparative investigation between phytophagous stink bugs has been performed yet. Here, the salivary proteins from two bugs, BMSB and SGSB, are analyzed using LC-MS/MS. Data are available via ProteomeXchange with identifiers PXD011920 and PXD011976. A total of 238 and 305 proteins are identified in salivary glands of BMSB and SGSB, respectively. In comparison with salivary proteome from other Hemiptera, the most striking feature of the salivary gland proteomes of SGSB and BMSB is the similar pattern of protein functions between both species. Some of the proteins are speculated to play a significant role in plant-insect interactions. The results herein provide a framework for future research to elucidate the molecular basis of differential impact of piercing-sucking insects on host plants.
入侵性的褐纹东方蝽（BMSB）和南方绿蝽（SGSB）在欧洲广泛分布，尽管引入时间和饮食习惯不同。半翅目害虫的唾液在昆虫与其宿主植物的相互作用中起着至关重要的作用。已经研究了几种蚜虫的唾液蛋白质组，并发现它们因物种而异，而尚未对植食性蝽类进行比较研究。在这里，使用 LC-MS/MS 分析了两种昆虫，BMSB 和 SGSB 的唾液蛋白。数据可通过 ProteomeXchange 获得，标识符为 PXD011920 和 PXD011976。在 BMSB 和 SGSB 的唾液腺中分别鉴定出 238 种和 305 种蛋白质。与其他半翅目昆虫的唾液蛋白质组相比，SGSB 和 BMSB 的唾液腺蛋白质组最显著的特征是两种物种之间蛋白质功能模式相似。一些蛋白质被推测在植物-昆虫相互作用中发挥重要作用。本研究结果为阐明刺穿性吸食昆虫对宿主植物的不同影响的分子基础提供了一个研究框架。
