Scientists are developing new ways to control mosquitoes, the animal that kills more people than any other on Earth. As the climate warms, mosquito seasons are growing longer, giving the insects more time to spread dangerous diseases such as malaria and dengue. Reports highlight how extended warm periods are expanding the threat to new regions and prompting research into novel control methods.

An essay argues that mosquito-borne diseases like malaria and dengue could be largely eliminated with existing tools, including gene-based mosquito suppression, vaccines, drugs and surveillance, and that continued deaths reflect a lack of will and funding rather than a lack of science. Readers are debating whether the claim holds up, citing past eradication campaigns, ecological concerns and the history of vector control programs.

Health researchers in Laos are working to identify which mosquito species are present along the country's porous borders, whether those insects carry mutations conferring resistance to the insecticides used against them, and where climate change might spread them next. The concern is a vector community that is more diverse and more genetically varied, making malaria and other mosquito-borne diseases harder to control in the region.

Health experts are sounding the alarm over mosquito-borne diseases such as dengue, malaria and chikungunya, warning that warming temperatures are expanding the habitats of disease-carrying mosquitoes into new regions. Longer breeding seasons and heavier rainfall are boosting mosquito populations, pushing public health agencies to reassess surveillance, prevention and vaccine strategies as outbreaks occur in areas once considered too cold for transmission.

Attention is turning to how a warming climate will affect malaria transmission. Rising temperatures and shifting rainfall patterns are expected to expand the areas where mosquitoes can survive, putting new populations at risk, while some currently endemic regions may see transmission decline. Experts are weighing where the disease burden will shift and how health systems should prepare for changing exposure.

A new essay in Works in Progress argues that mosquito-borne disease is not an inevitable fact of nature but a policy choice, since proven tools like insecticides, drains, and genetic control have already eliminated malaria from many countries. Readers are debating whether the real barrier is funding and political will rather than science, and what that implies for malaria eradication efforts today.

Health researchers warn that rising global temperatures are increasing Australia's risk of mosquito-borne diseases such as malaria and dengue, with the country's warmer north facing the greatest threat. The report highlights how shifting climates are expanding the range of disease-carrying mosquitoes, prompting calls for stronger public health preparedness.

Researchers at Yale School of Medicine report that antimalarial drugs can remain inside mosquitoes after a blood meal, continuing to expose malaria parasites to the drugs. The finding suggests mosquitoes themselves may sustain drug pressure on parasites, a factor that could influence how drug resistance develops and how malaria control strategies are designed.

New attention is being paid to how mosquitoes mate, with reports arguing that breeding behaviour could decide whether malaria control campaigns succeed or fail. Understanding mating swarms and reproduction patterns may improve strategies such as releasing sterile or genetically modified males to suppress mosquito populations and cut malaria transmission in affected regions.
