Johns Hopkins University Bloomberg School of Public Health
The chemical compound glyphosate, the world's most widely used herbicide, can weaken the immune systems of insects, suggests a study from researchers at the Johns Hopkins Bloomberg School of Public Health. Glyphosate is the active ingredient in Round Up™, a popular U.S. brand of weed killer products.

To the researchers, the results raise concerns that glyphosate and possibly other phosphate-containing compounds may be harming insect populations. Insects have many roles in the global ecosystem, and disrupting their populations could in turn have major adverse effects on people, for example in agriculture, and even in the realm of infectious diseases.
"Mosquitoes exposed to glyphosate were less able to control Plasmodium infections they would have otherwise resisted, which hints that glyphosate exposure may make them better vectors for malaria," Smith says. "These results raise concerns about the increasing use of glyphosate in regions of the world where malaria is endemic."
