Brazil will release billions of genetically modified mosquitoes against infectious disease: the effect remains to be seen how the source: the transgenic mosquitoes science network of Oxitec company from a Brazil city of Piracicaba container in gush. Photograph: Paulo Freidman Maria do Carmo every Saturday morning, Tunussi will let the neighbor search from door to door houses and courtyards, in search of any water storage and the breeding places for mosquitoes, such as pots, buckets and block the sink. Over the past 17 years, Tunussi has become a community health agent for CECAP Eldorado local clinics. CECAP Eldorado is a small town in Pilar Sica Ba, Brazil, has a population of about 5000 people, 2 hours northwest of St Paul. Tunussi has witnessed repeated dengue fever, nausea, and pain in people who suffer from joint pain. Therefore, her work sometimes seem futile. "You cleaned up the breeding ground the first day, and on the second day it came back." Tunussi said, "it never seems to end." In April this year, CECAP became the first Pilar Sica Ba to try new things in the community, which is a Tunussi that can not only eradicate dengue fever, but also prevent Zika virus a foothold mosquito control tool — OX513A. This is a kind of transgenic Aedes aegypti, through a lethal gene transfer to the offspring, reducing the number of Aedes aegypti. In the U.S. state of Florida, to cultivate these insects Oxitec plans to release them, but was blocking the public. However, in CECAP, residents seem to be from the company in the morning slowly moving the window in a caravan round remained poised attitude cloud of mosquitoes. This may be because dengue fever is so common there. Last year, the virus caused about 1 million 500 thousand Brazilians sick, and in July 2015 ~ in July this year, more than 1600 people in the city of Pilar Sica Ba so sick. The spread of Zika virus scare is magnified solutions for the local people to clean up outside the breeding ground of pesticides and interest, the former is not always effective in the fight against Aedes aegypti, which is difficult to remain year after year, although Tunussi has been trying to. Therefore, in the release of the world’s first genetically modified mosquitoes 7 years later, Oxitec chose to expand the scale of the test in Brazil is not surprising. It is shifting from small pilot projects such as CECAP to the planned release of thousands of people. Carrying lethal mosquito breeding Oxitec headquarters in Brazil is located in the industrial city of campinas. There, there is a smell of fish feed that feeds on mosquito larvae. The company can make about 4 million mosquitoes through the whole life cycle within a week from gray to gray powder mosquito eggs larvae twist, and then is similar to the size of a grain of rice, dense black pupa, and finally into the year mosquitoes flying in the plastic bucket and snack box about the size of the.
