VKM has assessed the environmental and health risks associated with the use of the mite Lepidoglyphus destructor as feed. Background Anso-Mite Plus consists of the biological control agent Amblyseius andersoni and the feed organisms Carpoglyphus lactis and Lepidoglyphus destructor. Amblyseius andersoni and C. lactis have previously been assessed by VKM. VKM has now assessed the environmental and health risks of L. destructor. Conclusions Lepidoglyphus destructor has been found in homes, agricultural environments, and stored products in Norway. The species is well established in Norway, and introduced individuals are expected to be able to establish and spread. Lepidoglyphus destructor is widespread and common in Norway, and it seems unlikely that further introductions via Anso-Mite Plus will have any additional effects on biodiversity. Several studies report allergies to mites, including to L. destructor. The likelihood of developing mite allergies after handling the product is therefore high. However, the likelihood of allergic reactions after consuming plants treated with the product appears to be low. Lepidoglyphus is not a species-rich genus, and there is no documentation suggesting that L. destructor can be confused with other species. The risk assessment is approved by VKM's Panel on Plant Health.

VKM has assessed the environmental and health risks associated with the use of the mites Acarus siro and Suidasia pontifica as feed for various predatory insects and mites. Background POWERFOOD 3.0 is used as feed for various predatory mites and predatory insects. Acarus siro, Suidasia pontifica, and Carpoglyphus lactis constitute the product. Carpoglyphus lactis has previously been assessed by VKM. VKM has now prepared an environmental and health risk assessment of A. siro and S. pontifica. Conclusions Acarus siro occurs naturally in Norway, and new introductions will most likely be able to establish and spread in Norway. Suidasia pontifica, on the other hand, has never been recorded in the wild in Norway, and its tropical origin suggests that it will not establish and spread in Norway. No records of negative effects of A. siro and S. pontifica on biodiversity were found. Several studies report allergies to mites, including the species in the product POWERFOOD 3.0. The likelihood of developing mite allergies after handling the product is therefore high. However, the likelihood of allergic reactions following consumption of plants treated with the product appears to be low. Regarding taxonomic challenges that may affect the risk assessment, VKM found out that A. siro can be mistaken for A. farris and A. immobilis. These species differ only slightly in development and ecology. From the limited available knowledge about their biology, these three species are expected to have similar effects on biodiversity and human health. There are no known problems with species identification for Suidasia pontifica. The taxonomic issue with this species is that much of the literature uses an invalid name; S. medanensis. The risk assessment is approved by VKM's Panel on Plant Health.

It is highly unlikely that Anagyrus vladimiri will be able to establish or spread in Norway. There are no native host organisms, and winter temperatures are too low. Therefore, it is likely that the parasitic wasp will not affect local biodiversity. Thus concludes the Norwegian Scientific Committee for Food and Environment (VKM). Background VKM has assessed the environmental risk of using the product Citripar in Norway. The risk assessment was carried out at the request of the Norwegian Food Safety Authority. Citripar, a product for biological control, is being sought for approval for use in Norway. The product contains the parasitic wasp Anagyrus vladimiri and is intended to be used against mealybugs, especially the species Planococcus citri and P. ficus, on fruits, berries, vegetables, and herbs in greenhouses and plastic tunnels, as well as on indoor plants. Conclusions There have been no reported observations of Anagyrus vladimiri in Norway. VKM assesses that Anagyrus vladimiri will not be able to establish and spread in Norway under current conditions. Anagyrus vladimiri will have no effect on biological diversity in Norway, as there are no known native host organisms that the wasp can parasitize. Individuals of what is now known as Anagyrus vladimiri were for many years identified as belonging to the species Anagyrus pseudococci. Anagyrus pseudococci and A. vladimiri belong to a complex of species that are almost impossible to distinguish from each other and are informally referred to as the Anagyrus pseudococci complex. The risk assessment is approved by VKM's Panel on Plant Health.
