Key message:
VKM shall assess the risk to biodiversity posed by using the predatory mite Stratiolaelaps scimitus to combat varroa mites (Varroa destructor) in apiaries.
The risk assessment has been commissioned by the Norwegian Environment Agency.
Background
Stratiolaelaps scimitus are small predatory mites that live in soil. Preparations with S. Scimitus is currently approved for biological control of Sciaridae (flies commonly known as dark-winged fungus gnats) found in greenhouses, plastic tunnels, and indoor planting. Such preparations are used especially for the cultivation of poinsettias and mushrooms, which are often susceptible to Sciaridae.
The Norwegian Environment Agency has requested a risk assessment since it has received an application for the use of the predatory mite to combat varroa mites in apiaries. The Agency has therefore asked VKM to assess the risk to biodiversity associated with new use of the predatory mite.
The Agency will use the report to determine whether they should permit the introduction and establishment of the species for use in apiaries as a biological control against varroa mites.
