**Summary:**
A growing global concern about mosquito-borne diseases, exacerbated by climate change, is sparking debate among scientists about the best strategies for mitigation. While some advocate for targeted mosquito eradication, others warn of potential ecological consequences and the insects’ demonstrated ability to develop resistance to insecticides. The article explores various alternative approaches, including genetic modification, sterile insect techniques, repurposing existing drugs, and introducing beneficial bacteria to prevent disease transmission. The consensus seems to be that a multi-pronged approach, combining different strategies, is the most effective way to combat mosquito-borne illnesses.

**Mosquitoes on the March: As Climate Warms, Experts Debate Eradication vs. Disease Control**
**Bengaluru, September 15, 2025:** As warmer temperatures expand the habitat of disease-carrying mosquitoes, scientists are grappling with how best to combat the rising threat of mosquito-borne illnesses like malaria and dengue fever. The debate centers on whether targeted eradication of disease-spreading species is a viable and responsible solution.
“Mosquitoes are now a global problem. As warmer temperatures allow them to breed in new geographies,” said Dr. Andrea Smidler, a molecular biologist at the University of California, San Diego (UCSD), “We can’t expect eradication to be permanent, right?”.
Some experts caution against widespread eradication efforts, citing potential ecological disruptions and the development of insecticide resistance. “Eradicating mosquitoes is similar to killing bacteria with antibiotics, it works very well in the beginning [but] gradually the bacteria become resistant to the antibiotics, and that’s exactly what’s happening with the mosquitoes.”, said Dr. Marcelo Jacobs-Lorena, an entomologist at the Johns Hopkins Bloomberg School of Public Health in Maryland.
Instead, a range of alternative strategies are being explored:
* **Genetic Modification:** CRISPR technology is being used to create sterile male mosquitoes that cannot produce offspring, leading to population crashes.
* **Sterile Insect Technique:** Male mosquitoes are sterilized with X-rays or genetic manipulation and released to mate with wild females, resulting in non-viable offspring.
* **Drug Repurposing:** Existing drugs, such as nitisinone, are being investigated for their mosquito-killing properties.
* **Beneficial Bacteria:** Introducing bacteria like Wolbachia and a new bacterium discovered by GlaxoSmithKline into mosquitoes can prevent the transmission of viruses like dengue fever and parasites like Plasmodium (which causes malaria), respectively.
“These different strategies should all be used together to stop mosquitoes from spreading diseases like malaria.”, said Dr. Lorena.
According to Dr. Scott O’ Neill, founder and CEO of the World Mosquito Program non-profit, they discovered that Wolbachia, a naturally occurring bacteria in some insects, protected these insects from viral infections. They transferred Wolbachia into Aedes aegypti mosquitoes and realised that the bacteria prevented dengue viruses from growing inside the mosquitoes. It could also be used to target chikungunya, yellow fever, and Zika viruses.
The World Health Organization (WHO) encourages research on genetically modified mosquitoes, emphasizing the need for clear governance mechanisms to assess health, environmental, and ecological implications.
Experts agree that a comprehensive, multi-pronged approach is crucial for effectively combating mosquito-borne diseases. This includes continued treatment of infected individuals, insecticide use, mosquito modification and the development of vaccines. While the debate on eradication continues, the focus is shifting towards innovative and sustainable methods to minimize the deadly impact of these adaptable insects.
