ScienceDaily (Aug. 13, 2010) — A combination of fungal spores and chemical insecticides are an effective way of combating insecticide-resistant malaria mosquitoes. Researchers at Wageningen UR and from Benin, West Africa, have shown that fungi and insecticides reinforce each other´s efficacy, and that the effect of using a combination of both is greater than the sum of using the two methods separately.
Their article in the August edition of PLoS ONE (Public Library of Science) claims that biological and chemical methods of fighting malaria can and should be used together.
It is estimated that world-wide, more than a million people die from the effects of malaria. Most of them live in the poorer African countries. Malaria parasites are transmitted from person to person by the Anopheles mosquito. In many areas, particularly West Africa, malaria mosquitoes are becoming increasingly resistant to chemical pesticides, and so the effect of impregnated mosquito nets and indoor sprays is wearing off. Last year, researchers from Wageningen showed that fungal spores were effective in killing mosquitoes and that they could even make the mosquitoes more vulnerable to pesticides. They therefore carried out follow-up research on the efficacy of combinations of fungi and insecticides against resistant malaria mosquitoes in West Africa…
