Invasive mosquito surveillance in the United Kingdom 2020 to 2024: First detection of Aedes aegypti eggs in the UK and further detection of Aedes albopictus.

ABSTRACT: Here, we provide an update on invasive mosquito surveillance activities coordinated by the UK Health Security Agency (UKHSA) between May 2020 and November 2024.

In 2024, vector surveillance to detect and limit the establishment of invasive mosquito species involved 1070 ovitraps at 117 localities across England, Wales and Northern Ireland, expanding from 58 in 2019. Ovitraps at seaports, airports, and highway transport hubs were examined every two weeks, between May and October, each year. In 2020, 2021 and 2022, no Ae. albopictus spe
