Targeting only mosquito larvae, and not adults, with insecticides may work in the short run, but could result in higher resistance in the insects and less disease immunity among humans, especially in urban settings, the study found.
Dengue is a mosquito-borne infection that causes severe, flu-like symptoms in some 50 million people every year, mainly in developing countries.
Global incidence of the disease, which is rarely fatal but often debilitating, has risen dramatically in recent decades, linked to both rapid urbanization and the impact of global warming. Some 2.5 billion people are at risk.
