Design and development of a high-resolution sensory system for detection of biogenic signals

在常年种植植物的温室里，种植者必须持续监测病虫害。 这种监控目前是通过视觉搜索错误来执行的，因此有害程序清洗是非常重要的 人工检查树叶顶部和底部是否有害虫的劳动密集型工作。视觉效果 在作物冠层的顶部、中部和底部进行检查。在一个中等大小的温室里，需要五个人 到六周内对温室内的所有植物进行物理检查。在全球市场上保持竞争力 因此，重要的是找到更有效、更少劳动密集型的监测方案。大多数植物都是 能够对周围环境的变化做出反应，并能够传达有关其总体情况的准确信息 通过这些反应了解健康状况。植物感知外界刺激并将其转化为 信号被传输到遥远的、非刺激的器官已经知道很长时间了。其中一个 植物对生物胁迫的反应是草食动物诱导的植物挥发物的释放，这是有充分证据的 (HIPV)-也称为信息化学品，因为它们携带一些关于 发射器。HIPV可以强烈影响捕食性和草食性节肢动物在自然界和 一些植物面临很大的选择压力，需要释放这些挥发物。最近的发现表明，植物可以 通过发生的一系列化学反应和电反应来识别食草动物并评估它们的威胁 在启动防御机制之前。植物的反应在感染的早期阶段就开始了，在 症状变得明显起来。这项研究是我们最近与 Ecoation Innovative Solutions Inc.(EIS)通过NSERC Engage基金，我们将进一步开发EIS 将监测范式从对植物的小细菌的物理检查转变为使用 植物作为有关自身健康和福祉的可靠信息来源，并远程监测 健康指示器信号。

In greenhouses where plants are grown year round, growers must continuously monitor for pests and diseases. This monitoring is currently performed by visually searching for bugs and thus pest scouring is a very labor-intensive task where the top and underside of the leaves are manually checked for pests. The visual inspection is done at the top, middle and bottom of the crop canopy. In an average size greenhouse, it takes five to six weeks to physically inspect all plants inside the greenhouse. To remain competitive in the global market place, it is important to find more effective and less labor-intensive monitoring protocols. Most plants are capable of responding to changes in their surroundings and can convey precise information about their overall health status through those responses. The ability of plants to sense external stimuli and translate them into signals that are transmitted to distant, non-stimulated organs has been known for a long time. One of the well-documented responses of plants to biotic stressors is the emission of herbivore induced plant volatiles (HIPVs) - also known as info-chemicals due to the fact that they carry some information about the status of the emitter. HIPVs can strongly affect the behaviour of both predatory and herbivorous arthropods in nature and some plants are under strong selection pressure to release these volatiles. Recent findings show that plants can recognize the herbivores and assess their threat via a series of chemical and electrical reactions that occur before activation of defensive mechanisms. The plant responses commence at early stages of infestation before the symptoms become visible. In this research, which is the continuation of our recent collaboration with Ecoation Innovative Solutions Inc. (EIS) through an NSERC Engage funding, we will further develop EIS's technology that shifts the monitoring paradigm form physical inspection of plants for small bugs to use the plants as reliable source of information about their own health and well-being and remotely monitor such health indicator signals.
