The dengue mosquito known as Aedes Aegipty 'has evolved to such an extent that today more easily reproduced and is immune to insecticides.
This 'super-mosquito' no longer reproduce only in clean water but also in the sewer, but not least, has become resistant to insecticides, so health authorities in Tabasco explores new ways to combat it.
Cases of dengue in the state increased by 800 percent this year, from 57 in 2011 to 474 so far in 2012.
Francisco Garcia Marco Hernandez, head of Vector and Zoonoses said the mosquito has become resistant because the insecticide used has been used for many years, making that impacts only 10 percent of the population of this vector.
"The dengue mosquito has changed their habits and customs, was once considered an urban insect that only lived in the city, domestic and totally linked to the shanty areas where there was trash. Was their livelihood, without But as the rural arrived plastics and tires, the mosquito began to play up to a cap of soda, "he warned.
He adds that the 'Aedes' before remained almost in one place, but now begins to move up to 300 meters in search of food, the larvae also have become more resistant to environmental conditions to such an extent that one can stay with life up to six months, expected to reach season moisture to reproduce.
Before the mosquito lived at an altitude of 600 meters above sea level, has now reached to 800 meters and parts over a thousand 200 meters, running from entomological control measures.
Before the new behavior of the mosquito the Ministry of Health has begun working with entoolog?a, such as 'ovitraps' where found to 500 thousand eggs and used to be lower.
Garcia Hernandez stated that "experience has made it clear that while we maintain a single type of insecticide, will be much easier than we get to build resistance to these insects."
Indicated that in such conditions, health authorities are on the verge of changing the insecticidal compound 'Phenothrin', which has been used for 4 years, by a body Phosphorous, to give the opportunity to become susceptible mosquitoes, and years return later to the insecticide that is used now.
'In the hands of citizens'
Alfonso Rodr?guez Le?n, Secretary of Health said that dengue is one of the biggest challenges in public health, because more than 80 percent of the problem is in the hands of the citizen who does not care that there is no reservoirs for the mosquito not play on rooftops, in courtyards, gardens.
Given all this, local authorities have urged people to remain vigilant and to intensify actions descacharrizaci?n and privilege as the yard clean.
