The use of the dye eosin methylene blue in the control fotodinu00e2mico insect vector Aedes Aegypt

摘要

The present invention is the use of the mixture of Azur II (mixture of oxidized Azur I and methylene blue) and eosinato azure II (dye formed by the combination equimolar azure I,Methylene blue and eosin yellowish eosin methylene blue), known as the second Giemsa (EAM) as the photosensitizing agent for the control fotodinu00e2mico (CF) of the insect vector, Aedes aegypti.It was evaluated the presence of dye in the nurseries, which was ingested and / or absorbed by the larvae, and after the irradiation of light.The dye induced larval death by oxidative stress due to production of oxygen singleto and / or other reactive species of oxygen (EROS).The mechanism of action of CF in the metabolism of the insect could be activated by illumination of the photosensitizers, intemalizado in the insect vector, when illuminated with white light.The light that can be proviniente both artificial sources (lasers, LEDs, halogen lamps, fluorescent lamps, and sodium tungsten, etc.) as a natural source (sunlight).
