Kaum tawm txhiab tus txiv neej yoov tshaj cum raug tso rau hauv cov tsiaj qus hauv Florida. Tab sis cov no tsis yog yoov tshaj cum zoo ib yam: Lawv tau hloov kho caj ces, thiab lawv tshwj xeeb tshaj tawm thoob plaws hauv lub xeev. Nws yog ib feem ntawm txoj kev npaj tiv thaiv kab mob los ntawm kev tso tawm 1 billion yoov tshaj cum thoob plaws ob lub xeev, tab sis nws ua rau qee tus neeg tshee.

Cov neeg ua haujlwm tau tso lub thawv ntawm cov qe yoov tshaj cum - ob ntawm Kuzhou Ki, ib qho ntawm Ramrod Key, thiab peb ntawm Waka Ki - rau hnub Thursday, thiab cia siab tias lawv yuav loj hlob hauv ib lub lis piam. Lawv yuav rov ua cov txheej txheem no nyob rau lub hlis tom ntej, tso 12,000 yoov tshaj cum hauv ib lub lis piam rau 12 lub lis piam. Tag nrho ntawm 144,000 yoov tshaj cum yog qias neeg.

Txoj haujlwm - thawj zaug tso tawm GMO yoov tshaj cum hauv Tebchaws Meskas - tau pib los ntawm Florida Keys Mosquito Control District (FKMCD) hauv kev koom tes nrog tus kheej lub tuam txhab British biotechnology Oxitec. Qhov no yog kev sim kom muaj kev sib kis ntawm tus kab mob dengue, Zika thiab kub taub hau daj.

Andrea Leal, tus thawj coj ntawm Florida Keys Mosquito Control District, tau hais tias "Raws li peb pom kev tiv thaiv qee yam ntawm peb txoj kev tswj hwm tam sim no, peb xav tau cov cuab yeej tshiab los tswj cov yoov tshaj cum no,"

Lub tswv yim yog tias GMO yoov tshaj cum yuav txo cov pejxeem ntawm Aedes aegypti, ib hom yoov tshaj cum nyob hauv Florida Keys uas kis tau cov kab mob no. Hauv Cov Ntsiab Lus, cov tsiaj no tsuas yog 4% ntawm tag nrho cov yoov tshaj cum. Tab sis xyoo tas los lawv tau ua rau 70 tus neeg mob dengue kub taub hau hauv Key Largo, thiab kev pheej hmoo ntawm lwm yam kab mob sib kis yog qhov kev txhawj xeeb loj.

Tsuas yog cov poj niam ntawm hom Aedes aegypti tom tib neeg kom tau ntshav rau qe kom loj hlob. Yog li ntawd, cov kws tshawb fawb tau tsim GMO yoov tshaj cum, uas lawv hu ua OX5034, los yug los ntawm cov poj niam uas tuag li larvae. Oxitec, lub tuam txhab tom qab GMO yoov tshaj cum, thiab FKMCD vam tias cov kab yuav ua phooj ywg nrog poj niam Aedes aegypti. Txij li cov xeeb ntxwv ntawm cov poj niam tsis tuaj yeem muaj sia nyob ntev txaus los yug me nyuam, qhov no yuav txo cov neeg yoov tshaj cum uas kis kab mob. Lawv cia siab lawm.

Qhov no tsuas yog thawj theem ntawm qhov project. Oxitec tau txais kev tso cai siv los ntawm Lub Chaw Tiv Thaiv Ib puag ncig kom tso tawm 1 billion ntawm cov yoov tshaj cum hloov pauv ntawm 6,600 daim av hauv Florida thiab Texas hauv ob xyoos tom ntej.

Oxitec lees tias txoj kev no yog "kev nyab xeeb" thiab "ib puag ncig tus phooj ywg". Lub tuam txhab khav theeb kev sim ua tiav hauv Cayman Islands, Panama, Malaysia thiab Brazil. Lub tuam txhab tseem sau tseg tias qhov project tau pom zoo los ntawm EPA thiab Florida Department of Agriculture thiab Consumer Services, thiab tau txais kev txhawb nqa los ntawm Lub Chaw Tiv Thaiv Kab Mob thiab pawg thawj coj ntawm cov kws pab tswv yim ywj pheej.

Tab sis cov neeg nyob hauv Kees tsis ntseeg tias nws yog ib lub tswv yim zoo los tso GMO yoov tshaj cum. Thiab lawv muaj laj thawj rau kev txhawj xeeb. Cov neeg hauv zos tau hais rau Vice tias lawv tsis tau ceeb toom txog qhov twg yoov tshaj cum yuav raug tso tawm kom txog rau hnub Friday ua ntej kev tso tawm pib. Qhov no yog, hais qhov tsawg tshaj plaws, careless thiab rude tus cwj pwm.

Ib txoj kev tshawb fawb Yale University 2019 kuj tau ceeb toom tias txoj kev npaj yuav rov qab los. Cov kws tshawb fawb no tau pom tias txawm hais tias feem ntau cov poj niam xeeb leej xeeb ntxwv los ntawm GM yoov tshaj cum tuag, 3% mus rau 4% ntawm lawv feem ntau muaj sia nyob mus rau cov neeg laus, thiab nws tsis paub meej tias lawv tsis muaj menyuam. Qhov no txhais tau hais tias los ntawm kev sib raug zoo nrog cov yoov tshaj cum kis kab mob, Oxitec yoov tshaj cum tuaj yeem tsim cov yoov tshaj cum hybrid uas tej zaum yuav muaj tshuaj tua kab ntau dua li yoov tshaj cum qus thiab ua rau kis kab mob ntau dua.

Tseem muaj kev txhawj xeeb txog yuav ua li cas cov yoov tshaj cum yuav cuam tshuam nrog cov ecosystems ntawm Florida Keys. Ib qho kev tshawb fawb txog yoov tshaj cum los ntawm Brazil tau pom tias cov noob los ntawm yoov tshaj cum tsim nyob rau hauv ib lub chaw kuaj mob kis thoob plaws cov yoov tshaj cum qus. Nws tsis paub meej tias qhov kev cuam tshuam ib puag ncig no tuaj yeem cuam tshuam li cas rau Florida Keys, uas yog kev txhawj xeeb vim tias thaj av ntawd yog tsev rau ntau hom kev ua neej nyob. Lub hli tas los, ib pawg kws tshaj lij ywj pheej tau ua pov thawj rau Florida Keys Mosquito Board hais txog cov teeb meem no. Cov neeg tawm tswv yim tau thov kom EPA tso tseg txoj haujlwm, txawm tias qee cov yoov tshaj cum tab tom yuav mus rau hauv cov qus.

Kev tso tawm cov yoov tshaj cum hloov pauv ua rau cov neeg nyob hauv Florida, ib puag ncig thiab cov tsiaj txhu muaj kev pheej hmoo nyob rau hauv nruab nrab ntawm kev kis tus kabmob kis, "Dana Perls, tus thawj coj saib xyuas zaub mov thiab thev naus laus zis ntawm Cov phooj ywg ntawm Lub Ntiaj Teb, tau hais hauv nqe lus." Qhov no tso tawm yoov tshaj cum mutant. yog mob siab rau ua kom Oxitec cov txiaj ntsig zoo tshaj plaws, tsis yog qhov xav tau los tawm tsam cov kab mob yoov tshaj cum."
