Washington - I-Trump Administration's Environmental Protection Agency icubungula ukugunyazwa “ngokuphuthumayo” kwesibulala-zinambuzane esibulala izinyosi ukuze sisetshenziswe kumahektha angaphezu kuka-57,000 ezihlahla zezithelo eMaryland, eVirginia nasePennsylvania, okuhlanganisa ama-apula, amaPentshisi namanectarine.
Uma kuvunyiwe, lokhu kuzophawula unyaka we-10 olandelanayo lapho izifundazwe zaseMaryland, Virginia, nasePennsylvania zithole ukukhululwa okuphuthumayo kokuthi i-dinotefuran iqondise izimbungulu ze-lacewing onsundu ezihlahleni zamapheya nezamatshe ezikhanga kakhulu izinyosi.Izifundazwe zifuna imvume elinganiselwe yokufafaza kusukela ngoMeyi 15 kuya ku-Okthoba 15.
IDelaware, iNew Jersey, iNorth Carolina kanye neWest Virginia bathole ukugunyazwa okufanayo eminyakeni eyi-9 edlule, kodwa akwaziwa ukuthi bayayifuna yini imvume ngo-2020.
"Isimo esiphuthumayo sangempela lapha ukuthi i-US Environmental Protection Agency ivame ukusebenzisa izinqubo zangemuva ukuze ivumele izibulala-zinambuzane ezinobuthi obuyingozi ezinyosini," kusho uNathan Donley, usosayensi ophezulu eSikhungweni Sezinto Eziphilayo.“Kuphela ngonyaka odlule, i-EPA yasebenzisa le nqubo yokukhululwa ukuze igweme ukubuyekezwa okuvamile kokuphepha futhi yagunyaza ukusetshenziswa kwama-neonicotinoid amaningana abulala izinyosi ezitshalweni ezingaba ngu-400,000.Lokhu kuxhashazwa budedengu kwenqubo yokukhululwa kumele kuphele.”
Ngaphezu kwezimvume eziphuthumayo ze-dinotefuran zezihlahla ze-apula, ipentshisi, ne-nectarine, iMaryland, iVirginia, nePennsylvania nazo zithole izimvume eziphuthumayo eminyakeni eyisishiyagalolunye edlule ukuze kusetshenziswe i-bifenthrin (isibulala-zinambuzane esinobuthi sePyrethroid) ukulwa nezinambuzane ezifanayo.
"Eminyakeni eyishumi kamuva, kuphephile ukusho ukuthi izinambuzane ezifanayo esihlahleni esisodwa azisesona isimo esiphuthumayo," kusho uTangli."Yize i-EPA ithi ivikela abathumbi bempova, iqiniso liwukuthi le nhlangano isheshisa ukwehla kwabo."
I-EPA ngokuvamile ivumela ukukhululwa kwezimo eziphuthumayo ezimweni ezibikezelwayo nezingamahlalakhona ezenzeke eminyakeni eminingi.Ngo-2019, iHhovisi Lomhloli Jikelele we-Environmental Agency laseMelika lakhipha umbiko owathola ukuthi ukuvunyelwa okujwayelekile kwale nhlangano kwezigidi zamahektha wezibulala-zinambuzane akuzange kulinganiswe ngempumelelo ubungozi empilweni yomuntu noma emvelweni.
Lesi sikhungo sifake isicelo esingokomthetho sicela i-EPA ukuthi ilinganisele ukukhululwa ezimeni eziphuthumayo kube yiminyaka emibili ukuze kuvinjelwe ukuhlukumeza okubi kakhulu kwalolu hlelo.
Ukugunyazwa okuphuthumayo kwe-neonicotinoid dinotefuran kuza njengoba i-EPA iphinda igunyaza ama-neonicotinoid amaningi ukuze asetshenziswe okungezona eziphuthumayo kwezinye zezitshalo zezwe ezitshalwa kakhulu.Isinqumo esihlongozwayo se-EPA Office of Pesticides sihluke kakhulu ezinqumweni ezisekelwe kwisayensi eYurophu naseCanada zokwenqabela noma ukukhawulela kakhulu ukusetshenziswa kwezibani ze-neon ngaphandle.
Umbhali wokubuyekeza okubalulekile kwesayensi ngokuncishiswa okuyinhlekelele kwezinambuzane uthe “ukunciphisa kakhulu ukusetshenziswa kwezibulala-zinambuzane” kuyisihluthulelo sokuvimbela ukushabalala kwezinambuzane ezifika ku-41% emhlabeni emashumini ambalwa eminyaka azayo.
I-Center for Biodiversity iyinhlangano kazwelonke engenzi nzuzo yokongiwa kwemvelo enamalungu angaphezu kwezigidi ezingu-1.7 nezishoshovu ze-inthanethi ezizinikele ekuvikeleni izilwane ezisengozini yokushabalala nezindawo zasendle.
