In a finding that may open promising new ways to attack malaria, scientists are reporting today that two fungi that are harmless to humans and the environment can be used to kill mosquitoes.
The fungi are already licensed in Western countries to control aphids, termites and other pests, according to two studies in the journal Science. One of the researchers, Dr. Matt B. Thomas, a biologist at Imperial College in London, estimated that a “deliverable product” could be ready in three to five years, if he could get money for further research.
Malaria kills more than one million people a year, mostly children under 5 and pregnant women, especially in Africa. Despite the advent of new drugs and better mosquito nets, some specialists say deaths may be increasing, largely because of bureaucratic delays among donors and breakdowns in African public health systems.
Moreover, mosquitoes eventually develop resistance to every chemical pesticide used on them, including DDT. No resistance to fatal fungi has been reported among agricultural pests, Dr. Thomas said.
Scientists not connected with the new research called the findings encouraging.
