To check grain storage insects for resistance, follow these instructions to send samples for testing.

  • Use a small, strong plastic container or two zip-lock bags that are well sealed.
    Do not provide air holes – insects will escape.
  • Place 20-100 insects with clean untreated grain into container or bags.
  • Do not overfill the container – leave some air space.
  • Label container with the date, your name and the silo / storage identification.
  • Provide all your contact details (address, phone and email) and a brief explanation of why you are seeking a resistance test, the storage type and details of any grain treatments.
  • If possible post early in the week so the insects are not left in the mail over the weekend.
