Botanic Gardens as early detection sites

This article in Insects journal, documents the aphid fauna recorded in five European botanic gardens in 2022 and 2023. Several alien aphid species were detected, including multiple new national records. Alien taxa were found both in outdoor living collections and in controlled environments such as glasshouses, nurseries, restricted areas, and plant shops, which may function as entry points as well as locations for early intervention. These findings illustrate the value of botanic gardens for documenting aphid diversity and supporting early detection of non-native species relevant to plant health and biosecurity.
