Systems and methods for determining a location of a pest infested and/or diseased plant

A system for determining a location of a pest infested and/or diseased plant, the system comprising:

• a plurality of spatially separated VOC sensors for detecting volatile organic compounds, VOCs, among a plurality of plants, the plurality of spatially separated VOC sensors adapted to be spatially distributed across a sensing area substantially corresponding to an area comprising the plurality of plants, and
• a database system having stored thereon a plurality of indications of respective distress VOCs and/or response VOCs, wherein each distress VOC is a VOC that is emitted by a pest infested and/or diseased plant and each response VOC is a VOC that is emitted by a plant in response to the plant detecting a distress VOC from a pest infested and/or diseased plant, and
• a data processing system that is configured to:
• receive from the plurality of sensors one or more signals indicative of a detected VOC and indicative of at least one location where the detected VOC is detected, and to
• based on the one or more signals from the plurality of VOC sensors, determine that the detected VOC corresponds to a distress VOC stored in the database system or determine that the detected VOC corresponds to a response VOC stored in the database system, and to
• based on determining that a distress VOC or response VOC has been detected, and based on the at least one location as indicated in the one or more signals, determine a location of a pest infested and/or diseased plant.
