AIMSurv: First pan-European harmonized surveillance of Aedes invasive mosquito species of relevance for human vector-borne diseases

Human and animal vector-borne diseases, particularly mosquito-borne diseases, are emerging or re-emerging worldwide. Six <i>Aedes</i> invasive mosquito (AIM) species were introduced to Europe since the 1970s: <i>Aedes aegypti</i>, <i>Ae. albopictus</i>, <i>Ae. japonicus</i>, <i>Ae. koreicus</i>, <i>Ae. atropalpus</i> and <i>Ae. triseriatus</i>. Here, we report the results of AIMSurv2020, the first pan-European surveillance effort for AIMs. Implemented by 42 volunteer teams from 24 countries. And presented in the form of a dataset named "AIMSurv Aedes Invasive Mosquito species harmonized surveillance in Europe. AIM-COST Action. Project ID: CA17108". AIMSurv2020 harmonizes field surveillance methodologies for sampling different AIMs life stages, frequency and minimum length of sampling period, and data reporting. Data include minimum requirements for sample types and recommended requirements for those teams with more resources. Data are published as a Darwin Core archive in the Global Biodiversity Information Facility- Spain, comprising a core file with 19,130 records (EventID) and an occurrences file with 19,743 records (OccurrenceID). AIM species recorded in AIMSurv2020 were <i>Ae. albopictus</i>, <i>Ae. japonicus</i> and <i>Ae. koreicus</i>, as well as native mosquito species.
