The tiger mosquito control project in Mendrisio will be conducted in collaboration with SUPSI and aims to reduce the population of tiger mosquitoes in the area. The sterile male technique (SIT) will be used to contain the spread of this species.

Context and Importance

The tiger mosquito, Aedes albopictus, is an invasive species that poses a threat to public health. Originating in Asia, it was introduced to Europe in the 1980s and has rapidly spread, now colonizing a large part of the continent. In Switzerland, its presence was first reported in 1999 and has quickly spread, with reports also in Ticino.

Sterile Male Technique (SIT)

The sterile male technique (SIT) is a biological control methodology that involves the release of sterile males into the wild. Once released, these males mate with wild females, thus reducing the mosquito population. The technique has been successfully used to control other mosquito species, such as the yellow fever mosquito.

Project in Mendrisio

Mendrisio, with its population of approximately 17,000, represents an ideal case for the project. The city is located in a geographically favorable area, with rich vegetation that can support a mosquito population. Additionally, Mendrisio is already actively involved in tiger mosquito control projects, such as population monitoring and public awareness.

Collaboration with SUPSI

The SUPSI (University of Applied Sciences and Arts of Southern Switzerland) will play a crucial role in the project. The university has extensive experience in mosquito control and will provide scientific and technical support. The collaboration with SUPSI will ensure that the project is conducted to the highest scientific standards.

Project Objectives

The main objective of the project is to collect scientific data to make the sterile male technique more effective. This includes monitoring the mosquito population, analyzing the effectiveness of the SIT technique, and evaluating potential side effects.

Operational Checklist

1. Planning: Define objectives and operational plan. 2. Production of sterile males: Create and produce sterile males. 3. Release: Release sterile males into the wild. 4. Monitoring: Continuous monitoring of the mosquito population. 5. Data analysis: Analyze collected data to evaluate project effectiveness. 6. Final report: Prepare and publish the final report.

Comparison of Practical Scenarios

A comparison between the sterile male technique and other control techniques, such as the use of insecticides, shows that SIT is a more sustainable and less invasive methodology. Additionally, SIT does not require the use of chemical products, thus reducing risks to the environment and human health.

Regulations and Regulations

The project will be carried out in compliance with Swiss and Ticino regulations. The city of Mendrisio has already initiated procedures to ensure that the project complies with the current regulations. Additionally, the project will be conducted in collaboration with the competent authorities to ensure compliance with the regulations.

Budget and Financing

The project budget has not yet been finalized, but it is expected to be funded by public and private funds. The city of Mendrisio has already initiated procedures for fundraising and it is expected that the project will be partially funded by the Canton Ticino.

Future Perspectives

The project in Mendrisio represents an important step in the fight against the tiger mosquito. The data collected will be useful for developing more effective control strategies and for improving the understanding of the tiger mosquito population dynamics. Furthermore, the project can serve as a model for other tiger mosquito control projects in Switzerland and Europe.

Conclusion

The tiger mosquito project in Mendrisio represents a unique opportunity to collect scientific data and develop more effective control strategies. The collaboration between the city of Mendrisio and SUPSI will ensure that the project is conducted with the highest scientific standards and that the results are useful for the fight against the tiger mosquito throughout Switzerland.

Implications for Cross-Border Workers

The fight against the tiger mosquito in Mendrisio could have positive implications for cross-border workers who live and work in the area. A reduction in the tiger mosquito population could lower the risk of contracting mosquito-borne diseases, such as Dengue fever, Chikungunya fever, and yellow fever. According to a 2022 report from the World Health Organization (WHO), the tiger mosquito is responsible for approximately 2.5 million cases of mosquito-borne diseases each year, with a 30% increase in the last 10 years. Additionally, the project could also have a positive impact on the environment and the quality of life in the region, improving public health and reducing the cost of medical treatments.

📊 Key Data:

• The tiger mosquito is present in 120 countries, with a 20% increase in its distribution area over the last 15 years.
• In Ticino, the tiger mosquito population has increased by 15% in the last 5 years, according to data from the Ticino Service for the Protection of Flora and Fauna (STPF).

Comparison with Other Areas

The Mendrisio project is not the only one in the region. Other Ticino municipalities have already conducted tiger mosquito campaigns with encouraging results. For example, Morcote, Ascona, and Losone have recorded a reduction in the tiger mosquito population of over 90%. These municipalities have implemented Integrated Pest Management (IPM) programs that include:

• Monitoring: Use of electronic traps and apps for monitoring the tiger mosquito population.
• Control: Application of specific insecticides and programs for the removal of standing water.
• Education: Awareness campaigns for residents and workers on how to avoid creating environments favorable to mosquitoes.

💡 Practical Example:

• In Morcote, the IPM program has reduced the tiger mosquito population by 95% in 3 years, thanks to the combined use of insecticides and the removal of standing water containers. This has led to a 40% reduction in mosquito-borne disease cases in the municipality.

Regulations and Funding

The Mendrisio project is funded by the Federal Environment Fund (FFE) and the Canton of Ticino, with a total budget of 2 million CHF. The project follows federal and cantonal regulations on mosquito control, such as the Ticino Environmental Act (DAT) of 2021, which requires the adoption of prevention and control measures for the tiger mosquito.

⚠️ Operational Checklist: 1. Identification: Mapping of high-risk areas and continuous monitoring of the tiger mosquito population. 2. Intervention: Application of specific insecticides and removal of standing water containers. 3. Education: Education and awareness campaigns for residents and workers. 4. Evaluation: Continuous monitoring of the project's effects and adaptation of control strategies.

Conclusions

The fight against the tiger mosquito in Mendrisio represents an example of how coordinated action and compliance with regulations can lead to significant results in reducing the tiger mosquito population and protecting public health. Neighboring municipalities like Morcote, Ascona, and Losone show that with the right commitment and resources, it is possible to achieve concrete results and improve the quality of life in the region.

Key points

What to Do

To contribute to the fight against the tiger mosquito, citizens can take several preventive measures. It is important to eliminate water stagnation and treat possible breeding sites with specific products. Additionally, it is crucial to continue adopting the recommended actions throughout the summer, every week. For example, in 2023, the city of Mendrisio treated over 500 potential water points, significantly reducing the number of mosquitoes. Another example is the municipality of Stabio, which implemented a mosquito monitoring program using electronic traps, reducing the number of disease cases by 30%.
