Spring Bites on Hold, But Summer Sting Still Looms: German Tiger Mosquito Invasion a Concern
Mosquito activity temporarily decreases due to drought conditions, but this respite may not last through the summer.
The drought caused by climate change has its perks: It makes midge breeding more challenging, resulting in fewer of them this spring. However, summer may bring a different story, experts warn. The spreading Asian tiger mosquito is causing alarm.
"We've witnessed far fewer biting midges this year due to the severe drought leaving fewer breeding spots," explains Renke Lühken from the Bernhard Nocht Institute for Tropical Medicine in Hamburg. Springtime wetlands, where midges usually thrive, are baking dry, and even artificial breeding sites like rain barrels are empty.
Entomologists such as Carsten Pusch, deputy state chairman of the nature conservation union (NABU) in Schleswig-Holstein, concur, reporting, "I've never seen such a low number of biting midges as this year."
Yet, this season's dip might not mean summer relief. "Spring drought has no impact on the bite count in summer," emphasizes expert Lühken. "We could still be swatting away countless midges in July and August." Summer's heavy rains could trigger a midge boom, as their eggs can survive drought for years.
Tiger Mosquito: Carrying Deadly Viruses onto German Soil
Established in southern Germany since 2011, the Asian tiger mosquito (Aedes Albopictus) is marching its way up. "The species is moving northwards and will likely expose Germany to tropical viruses in the near future," explains Lühken.
The German Environment Agency notes that tiger mosquitoes in affected regions can transmit West Nile, dengue, and Zika viruses. Berlin's health department advises locals to report suspected Asian tiger mosquitoes to authorities.
These mosquitoes are smaller than a euro cent coin, have a black body, unique white patterns, five white rings on their hind legs, and a white longitudinal stripe on the front thorax. If preserved carefully without crushing, caught examples can help scientists confirm their identity.

Additional Insights:
- Geographical Expansion: The Asian tiger mosquito originates from tropical regions, but its habitat's expansion northwards due to climate change poses an increasing threat to public health in Europe.
- Local Transmission: As these mosquitoes continue to spread, experts fear that they could transmit tropical viruses that have previously been rare in Europe, such as dengue, chikungunya, Zika, and West Nile virus.
- Personal Protective Measures: To reduce the risk of mosquito bites, health authorities recommend wearing light, loose, and long clothing, using mosquito repellent, and eliminating small water containers that could serve as mosquito breeding sites around homes and gardens.
- Regional Restrictions and Control Measures: Regions such as South Tyrol in Italy have implemented strict regulations and fines to control the mosquito infestation, signaling potential measures Germany may adopt.
- Global Collaboration: Collaborative research to combat the spread of these mosquitoes and the viruses they carry is ongoing, emphasizing the importance of international cooperation in addressing vector-borne disease threats.
- The Commission, being consulted on the draft directive, may need to address the potential health and wellness risks associated with the spreading Asian tiger mosquito, which carries deadly viruses like West Nile, dengue, and Zika.
- As the Asian tiger mosquito, a species of medical-conditions concern, continues to expand its habitat, environmental scientists must consider the implications of climate change on its movement and the subsequent viral threats it poses.
- With the concern of the Asian tiger mosquito invasion and the potential for tropical viruses to impact public health, the importance of scientific research in health-and-wellness, environmental-science, and infectious diseases cannot be overstated.
