A la espera de que sea autorizado, este experimento sin precedentes en Estados Unidos, ha puesto en alerta a los habitantes<\/strong><\/span><\/p>\n

…..<\/strong><\/span><\/p>\n

…….<\/strong><\/span><\/p>\n

<\/strong><\/span><\/p>\n


\nPodr\u00eda parecer la escena de una pel\u00edcula de terror de bajo presupuesto, pero es real y ocurre en Florida, donde el gobierno federal se prepara para autorizar un experimento que podr\u00eda liberar a cientos de miles de mosquitos gen\u00e9ticamente modificados<\/strong><\/span><\/p>\n

<\/strong><\/p>\n

<\/strong>……<\/p>\n

……………<\/span><\/p>\n

<\/span><\/p>\n

La iniciativa busca reducir el riesgo de dengue <\/a>en el tur\u00edstico Cayo Hueso<\/strong> y, caso de ser autorizada por la Administraci\u00f3n de Alimentos y Medicinas, ser\u00eda el primer experimento de este tipo llevado a cabo en EE.UU., lo que preocupa a los habitantes, alarmados por el riesgo que los mosquitos transg\u00e9nicos<\/a> podr\u00edan representar para el fr\u00e1gil ecosistema la zona.<\/span><\/p>\n

…………….<\/span><\/p>\n

El experimento que planean las autoridades de control de mosquitos y la empresa brit\u00e1nica Oxitec consiste en <\/span>la liberaci\u00f3n de mosquitos machos -que no pican, a diferencia de las hembras-\u00a0 y que han sido modificados gen\u00e9ticamente para transmitir un defecto cong\u00e9nito que matar\u00eda a su descendencia antes de alcanzar la madurez. La idea es que se apareen con hembras y que sus cr\u00edas mueran antes de reproducirse<\/strong>.<\/span><\/p>\n

…………..<\/span><\/p>\n

Al cabo de algunas generaciones, se extinguir\u00eda el mosquito de la fiebre amarilla (Aedes aegypti), reduciendo con ello el riesgo de dengue sin necesidad de usar pesticidas<\/strong> y con un gasto relativamente bajo, aseguran los autores del experimento. Las autoridades indican que los genes modificados desaparecer\u00e1n del entorno una vez los mosquitos transg\u00e9nicos mueran y que, precisamente por ello, no se producir\u00e1n cambios en la poblaci\u00f3n silvestre de estos insectos.<\/span><\/p>\n

……………<\/span><\/p>\n

A pesar del optimismo de sus autores, la agente inmobiliaria Mila de Mier confes\u00f3 a AP su<\/strong> preocupaci\u00f3n, que comparte gran parte de la poblaci\u00f3n. No en vano, su petici\u00f3n \u00abDi no a los mosquitos modificados gen\u00e9ticamente liberados en los Cayos de la Florida\u00bb suma ya m\u00e1s de 117.000 firmas.<\/span><\/p>\n

……………<\/span><\/p>\n

\u00bb Casi todos los experimentos con cultivos gen\u00e9ticamente modificados<\/a> han acarreado secuelas no deseadas<\/strong>: \u2018supermalezas\u2019 m\u00e1s resistentes a los herbicidas o insectos modificados resistentes que conllevan da\u00f1os colaterales para los ecosistemas\u00bb, matiz\u00f3.<\/span><\/p>\n

……………… <\/strong><\/span><\/p>\n

<\/strong><\/p>\n

Actualmente no existe vacuna para el dengue.<\/strong> Se cre\u00eda que la enfermedad hab\u00eda sido erradicada en Estados Unidos hasta que surgieron 93 casos en los Cayos en 2009 y 2010.<\/span><\/p>\n

Florida, with the fly in the ear concerned changing dengue mosquitoes<\/span><\/p>\n

…….<\/span><\/p>\n

While waiting for it to be approved, this unprecedented experiment in the United States, has alerted the inhabitants<\/span><\/p>\n

…..<\/span><\/p>\n

…….<\/span><\/p>\n

<\/span><\/p>\n

<\/span><\/p>\n

It might seem a scene from a horror movie low budget, but it is real and true in Florida, where the federal government is prepared to authorize an experiment that could release hundreds of thousands of genetically modified mosquitoes<\/span><\/p>\n

<\/span><\/p>\n

……<\/span><\/p>\n

……………<\/span><\/p>\n

<\/span><\/p>\n

The initiative seeks to reduce the risk of dengue in Key West resort and if authorized by the Food and Drug Administration, would be the first such experiment conducted in the U.S., what worries people, alarmed by the risk that transgenic mosquitoes could pose to the fragile ecosystem in the area.<\/span><\/p>\n

…………….<\/span><\/p>\n

<\/span><\/p>\n

The experiment that authorities plan to control mosquitoes and the British company Oxitec is releasing male mosquitoes do not bite, unlike females, and that have been genetically modified to transmit a birth defect that would kill their offspring before reaching maturity. The idea is to mate with females and their offspring die before reproducing.<\/span><\/p>\n

…………..<\/span><\/p>\n

After a few generations, would die the yellow fever mosquito (Aedes aegypti), thereby reducing the risk of dengue without using pesticides and with a relatively low cost, say the authors of the experiment. The authorities indicate that the modified genes disappear from the environment once GM mosquitoes die and that is precisely why there is no change in the wild population of these insects.<\/span><\/p>\n

……………<\/span><\/p>\n

Despite the optimism of the authors, the realtor Mila de Mier AP confessed their concern, which shares much of the population. Not surprisingly, his petition \u00abSay no to genetically modified mosquitoes released in the Florida Keys\u00bb and adds more than 117,000 signatures.<\/span><\/p>\n

……………<\/span><\/p>\n

<\/span><\/p>\n

\u00abAlmost all experiments with GM crops have brought unintended consequences: ‘superweeds\u00bb resistant to herbicides or insects resistant modified involving collateral damage to ecosystems, \u00abhe added.<\/span><\/p>\n

………………<\/span><\/p>\n

<\/span><\/p>\n

There is no vaccine for dengue. It was believed that the disease had been eradicated in the United States until 93 cases arose in \u00a02009 and 2010.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
