    Sensor-based plant diagnosis techniques to monitor plant physiological status are important for agricultural production in highly sophisticated greenhouses. Plants emit a broad range of volatile organic compounds and its emission profile changes depending on the plant's physiological status. We demonstrated a detection of tomato russet mite damages occurred on stems of tomato plants grown in a semi-commercial greenhouse with an inexpensive- And handy- gas analysis instrument. The results proved that the tomato russet mite damage significantly decreased the amount of terpenes stored in trichomes on the main stem
