Several populations of malaria mosquitos were previously discovered to have different irritability to two insecticides of the organophosphorous group, such as fenitrothion and malathion. Individual comparison of fenitrothion and malathion irritability levels in laboratory colonies of Anopheles stephensi, An. atroparvus, Culex pipiens, Aedes aegypti, and Ae. togoi and in the natural population of An. martinius has shown that irritability to the two chemicals is specific in all the six species. This is probably due to recognizing the insecticide molecules by means of a so-called "living group" which has different structure in fenitrothion and malathion. |
