Two-spotted spider mites (TSSM; Tetranychus urticae Koch) feed directly on plants and can cause damage on a range of crops, including strawberries, raspberries, blackberries, tomatoes, eggplants, and cucumbers. They can cause serious yield loss in high infestations. They are often an issue in greenhouse crops as they thrive in hot and dry conditions. Each guide contains integrated pest management (IPM) information tailored for small-scale production, but the guidelines can be applied to all operation sizes. It includes:

  • Identification and lifecycle details including photographs of pest phases
  • Information about how and when to monitor
  • Options for biological, cultural, physical and chemical control

These resources was developed as part of a 12-guide series for small-scale vegetable and berry farmers in the Fraser Valley and Lillooet-Pemberton areas. Growers in other regions of BC may also find the information applicable to their local conditions.
