Unstoppable Asian Tiger Mosquito: Threat to Virus Transmission and an Unpredictable Future for Biting Midges
The Shift in Biting Midge Populations
Dry weather hinders mosquito development – a temporary relief that may last until summer's arrival.
Currently, it seems spring has granted a respite from biting midges. Observers note a significant drop in their numbers with Renke Lühken, from the Bernhard Nocht Institute for Tropical Medicine in Hamburg, stating, "The drought means fewer breeding spots, hence, fewer biting midges."
However, this relief may not last beyond the summer months as Lühken warns, "This dry spring has no bearing on how the summer will pan out regarding biting midges." For example, in cases of flood midges, their hardy eggs can remain dormant through drought periods, and heavy summer rains could trigger another midge plague.
The Asian Tiger Mosquito: An Unwelcome Guest
The expansion of the Asian tiger mosquito, formally known as Aedes albopictus, remains a concern. Originally from Southeast Asia, this mosquito species has been making its way into Germany for the past decade, with its maturing population now reaching Berlin. As Lühken puts it, "It's here to stay, and it's going to initiate the transmission of truly tropical viruses in Germany in the future."
Viruses and Climate Change: A Deadly Connection
The Federal Environment Agency has identified the Asian tiger mosquito as capable of transmitting West Nile, dengue, and Zika viruses in affected regions. In some areas of Germany, health departments are encouraging people to report and submit dead Asian tiger mosquitoes for examination. To do so, one should trap the small, black insect, with white patterns, five white rings on the hind legs, and a white longitudinal stripe on the front back without harm, freeze it overnight, and submit it in a container as soon as possible.
Preparing for an Increased Risk
As the Asian tiger mosquito continues its spread, experts stress the importance of monitoring and controlling mosquito populations in Germany. With a warming climate possibly creating more favorable habitats, there is an increased risk of these viruses becoming endemic in the country. Public health preparedness will be essential in addressing this looming threat.
In essence, the emergence of the Asian tiger mosquito in Germany highlights the need for vigilance, proactive measures, and a clear understanding of how climate change can alter insect populations and bring new disease risks.

The Commission has also been consulted on the draft directive related to the emerging Asian tiger mosquito in Germany, as health-and-wellness concerns arise due to the mosquito's potential to transmit West Nile, dengue, and Zika viruses. This situation underscores the importance of environmental-science research in understanding how climate change might impact insect populations and introduce new disease risks, necessitating proactive measures for public health preparedness.
