Environmental and human health risk assessment of Lepidoglyphus destructor in the product Anso-Mite Plus

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 provides independent scientific assessments of issues that are important for the environment and safe food. VKM does not give advice or take a position on how the risk should be managed. We can investigate the consequences of various alternative actions, but our commissioners decide how to manage risk.
