Asian Hornet Invasion Prompts Caution and Control Measures in Germany

The Asian hornet (Vespa velutina) has spread across several German states since its first detection in 2014, prompting the EU to list it as an invasive species. The hornet preys on native insects, including honey‑bees and wild bees, and can cause crop losses by feeding on grapevines and other fruit. While its sting is not considered more dangerous than that of native hornets, authorities warn against attempting to remove nests oneself, as this can harm protected European hornets and pose safety risks. Sightings should be reported to regional environmental agencies, which provide identification guidance and manage control efforts.

The green peach aphid (Myzus persicae), a 2‑mm insect also present in German gardens, feeds on plant sap and transmits viruses and bacteria that can damage fruit and vegetable crops. Infestations are identified by sticky honeydew, curled yellow leaves, and reduced yields. Control methods include encouraging natural predators such as ladybird larvae, lacewings, and parasitic wasps, and using plant‑friendly practices to attract these beneficial insects.
