蚜虫是重要的经济害虫，造成广泛的摄食损害和传播病毒。虽然有些物种有广泛的宿主范围，并对各种作物造成损害，但其他物种仅限于密切相关的植物物种。蚜虫在探测和取食时，会分泌含有效应物的唾液进入宿主体内，以操纵宿主细胞过程并促进侵染。蚜虫效应发现研究指出了植物病原体和蚜虫的感染和侵染策略之间的相似之处。有趣的是，已知对一些蚜虫物种的抗性涉及具有典型NB-LRR结构域结构的植物抗性蛋白。这些抗性蛋白是否真的识别蚜虫效应子以触发ETI仍有待阐明。此外，最近显示，未知的蚜虫衍生的激发子可以启动活性氧（ROS）产生和胼胝质沉积，并且这些反应依赖于BAK 1（油菜素不敏感1-相关受体激酶1），BAK 1是植物免疫系统的关键组分。此外，巴克-1有助于非主机抗蚜虫指向植物病原体和蚜虫之间的相互作用的另一个平行。了解植物免疫和非宿主抗性对蚜虫的作用对于制定持久和可持续的蚜虫控制策略至关重要。虽然昆虫行为在寄主选择和非寄主抗性中起作用，但一个重要的观察结果是蚜虫通过探测叶面与非寄主植物相互作用，但不能进食或建立定殖。因此，我们假设蚜虫在分子水平上与非宿主植物相互作用，但在抑制植物防御和/或释放营养物质方面可能不会成功。
Aphids are economically important pests that cause extensive feeding damage and transmit viruses. While some species have a broad host range and cause damage to a variety of crops, others are restricted to only closely related plant species. While probing and feeding aphids secrete saliva, containing effectors, into their hosts to manipulate host cell processes and promote infestation. Aphid effector discovery studies pointed out parallels between infection and infestation strategies of plant pathogens and aphids. Interestingly, resistance to some aphid species is known to involve plant resistance proteins with a typical NB-LRR domain structure. Whether these resistance proteins indeed recognize aphid effectors to trigger ETI remains to be elucidated. In addition, it was recently shown that unknown aphid derived elicitors can initiate reactive oxygen species (ROS) production and callose deposition and that these responses were dependent on BAK1 (BRASSINOSTERIOD INSENSITIVE 1-ASSOCIATED RECEPTOR KINASE 1) which is a key component of the plant immune system. In addition, BAK-1 contributes to non-host resistance to aphids pointing to another parallel between plant-pathogen and – aphid interactions. Understanding the role of plant immunity and non-host resistance to aphids is essential to generate durable and sustainable aphid control strategies. Although insect behavior plays a role in host selection and non-host resistance, an important observation is that aphids interact with non-host plants by probing the leaf surface, but are unable to feed or establish colonization. Therefore, we hypothesize that aphids interact with non-host plants at the molecular level, but are potentially not successful in suppressing plant defenses and/or releasing nutrients.
