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

在全年种植植物的温室中，种植者必须持续监测病虫害。 这种监测目前是通过视觉搜索错误来执行的，因此害虫冲刷是一个非常重要的问题。 这是一项劳动密集型任务，需要人工检查叶子的顶部和底部是否有害虫。视觉 在作物冠层的顶部、中部和底部进行检查。在一个普通大小的温室里， 对温室内的所有植物进行物理检查。在全球市场保持竞争力 因此，重要的是找到更有效和劳动强度更低的监测协议。大多数植物都是 能够对周围环境的变化做出反应，并能准确地传达有关其整体状况的信息。 健康状况通过这些反应。植物感知外界刺激并将其转化为 传输到远处的、未受刺激的器官的信号早已为人所知。之一 植物对生物胁迫的一种有据可查的反应是由食草动物诱导的植物挥发物的释放 （HIPV）-也被称为信息化学品，因为它们携带了一些关于 发射器。HIPV可以强烈影响自然界中捕食性和草食性节肢动物的行为， 一些植物在强烈的选择压力下释放这些挥发物。最近的研究表明，植物可以 通过一系列的化学和电子反应， 在启动防御机制之前。植物的反应开始于侵染的早期阶段， 症状变得明显。在这项研究中，这是我们最近与 生态创新解决方案公司(EIS)通过NSERC Engage基金，我们将进一步开发EIS的 该技术将监测模式从对植物进行物理检查以发现小虫子， 植物作为关于其自身健康和福祉的可靠信息来源， 健康指标信号。

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.
