Bo-rasaense ba fumane hore phekolo ea likokoana-hloko tsa liphoofolo tse ruuoang lapeng e chefo linokeng tsa Engelane |Meriana e bolaeang likokoanyana

Nyakišišo e bontšhitše gore dibolaya-dikhunkhwane tšeo di nago le mpholo kudu tšeo di dirišwago go dikatse le dimpša go bolaya matsetse di tsenya mpholo dinokeng tša Engelane.Bo-rasaense ba re se sibolotsoeng se “tsoalana haholo” le likokoanyana tsa metsing le litlhapi le linonyana tse itšetlehileng ka tsona, ’me ba lebeletse ho baka tšenyo e khōlō tikolohong.
Boithuto bo fumane hore ho 99% ea lisampole tse tsoang linokeng tse 20, litaba tsa fipronil li ne li le holimo, 'me kakaretso ea sehlahisoa se bola ka chefo e chefo e ne e le makhetlo a 38 ho feta moeli oa polokeho.Fenoxtone e fumanoang nokeng le moemeli e mong oa methapo e bitsoang imidacloprid e thibetsoe mapolasing ka lilemo tse ngata.
Ho na le lintja tse ka bang limilione tse 10 le likatse tse limilione tse 11 UK, 'me ho hakanngoa hore 80% ea batho ba tla fumana phekolo ea matsetse (ho sa tsotellehe hore na ho hlokahala kapa che).Bafuputsi ba boletse hore tšebeliso e foufetseng ea phekolo ea letsetse ha e khothalletsoe, 'me ho hlokahala melao e mecha.Hajoale, kalafo ea matsetse e amoheloa ntle le tlhahlobo ea tšenyo ea tikoloho.
Rosemary Perkins oa Univesithi ea Sussex, ea neng a okametse lipatlisiso, o itse: “Fipronil ke e ’ngoe ea lihlahisoa tsa matsetse tse sebelisoang ka ho fetisisa.Liphuputso tsa morao-rao li bontšitse hore e ka theoleloa ho likokoanyana tse ngata ho feta fipronil ka boeona.Metsoako e chefo e eketsehileng.”"Liphetho tsa rona li tšoenya haholo."
Dave Goulson, setho sa sehlopha sa bafuputsi le eena Univesithing ea Sussex, o itse: “Ha ke lumele ka ho feletseng hore chefo e bolaeang likokoanyana e atile hakana.Hangata linoka tsa rona li silafatsoa ke lik’hemik’hale tsena tse peli ka nako e telele..
O ile a re: “Bothata ke hore lik’hemik’hale tsena li sebetsa hantle haholo,” esita le ka tekanyo e nyenyane."Re tšepa hore li tla ba le phello e kholo bophelong ba likokoanyana tse nokeng."O ile a re sebolaya-dikhunkhwane se sebedisang imidacloprid ho alafa matsetse a dintja tsa boholo bo mahareng se lekane ho bolaya dinotshi tse dimilione tse 60.
Tlaleho ea pele ea litekanyetso tse phahameng tsa li-neonicotinoids (tse kang imidacloprid) linōkeng li entsoe ke sehlopha sa tlhokomelo ea Buglife ka 2017, le hoja thuto e ne e sa kenyelletsa fipronil.Likokoanyana tsa metsing li hlaseloa ke li-neonicotinoids.Liphuputso tse entsoeng Netherlands li bontšitse hore tšilafalo ea nako e telele ea litsela tsa metsing e entse hore palo ea likokoanyana le linonyana e fokotsehe haholo.Ka lebaka la tšilafalo e meng e tsoang mapolasing le likhoerekhoere, likokoanyana tsa metsing le tsona lia fokotseha, 'me ke 14% feela ea linōka tsa Brithani tse nang le bophelo bo botle ba tikoloho.
Patlisiso e ncha, e phatlalalitsoeng koranteng ea Comprehensive Environmental Science, e kenyelletsa litlhahlobo tse ka bang 4,000 tsa lisampole tse bokelletsoeng ke Setsi sa Tikoloho linokeng tse 20 tsa Borithane lipakeng tsa 2016-18.Tsena li tloha ho Teko ea Noka e Hamphire ho ea Nokeng ea Edene e Cumbria.
Fipronil e ile ea fumanoa ho 99% ea lisampole, 'me sehlahisoa se chefo haholo sa Fipronil sulfone se fumanoe ho 97% ea lisampole.Karolelano ea mahloriso ke makhetlo a 5 le makhetlo a 38 ho feta moeli oa chefo e sa foleng, ka ho latellana.Ha ho na lithibelo tsa molao ho lik'hemik'hale tsena UK, kahoo bo-rasaense ba sebelisitse tlaleho ea tlhahlobo ea 2017 e hlahisitsoeng bakeng sa Boto ea Taolo ea Boleng ba Metsi ea California.Imidacloprid e fumanoe ho 66% ea lisampole, 'me moeli oa chefo o ne o fetisitsoe linokeng tse 7 ho tse 20.
Fipronil e ne e thibetsoe ho sebelisoa mapolasing ka 2017, empa e ne e sa sebelisoe hangata pele ho moo.Imidacloprid e ne e thibetsoe ka selemo sa 2018 mme esale e sebelisoa ka seoelo lilemong tsa morao tjena.Bafuputsi ba fumane tekanyo e phahameng ka ho fetisisa ea chefo e bolaeang likokoanyana ka tlaase ho moo ho hloekisoang metsi, e leng se bontšang hore libaka tsa litoropo ke tsona mohloli o ka sehloohong, eseng masimo.
Joalo ka ha bohle re tseba, ho hlatsoa liphoofolo tse ruuoang lapeng ho ka sutumelletsa fipronil ka har'a likhoerekhoere ebe e kena ka nokeng, 'me lintja tse sesang nokeng li fana ka mokhoa o mong oa tšilafalo.Gulson o itse: “E tlameha ebe ena ke phekolo ea matsetse e bakileng tšilafalo.”Ha e le hantle, ha ho na mohloli o mong o ka nahanoang.
UK, ho na le lihlahisoa tse 66 tse ngolisitsoeng ka molao tsa bongaka ba liphoofolo tse nang le fipronil le lithethefatsi tse 21 tsa bongaka ba liphoofolo tse nang le imidacloprid, tseo bongata ba tsona li rekisoang ntle le lengolo la ngaka.Ho sa tsotellehe hore na phekolo ea letsetse e ea hlokahala, liphoofolo tse ngata tsa lapeng li phekoloa khoeli le khoeli.
Bo-rasaense ba re sena se lokela ho shejoa bocha, haholo-holo mariha ha matsetse a sa tloaeleha.Ba boletse hore le melaoana e mecha e lokela ho shejoa, joalo ka e hlokang litaelo le ho lekola likotsi tsa tikoloho pele e lumelloa ho sebelisoa.
"Ha u qala ho sebelisa mofuta ofe kapa ofe oa chefo e bolaeang likokoanyana ka tekanyo e kholo, hangata ho na le liphello tse sa lebelloang," Gulson o itse.Ho hlakile hore ho bile le phoso.Ha ho na ts'ebetso ea taolo bakeng sa kotsi ena e khethehileng, 'me ka ho hlaka e hloka ho etsoa.”
Matt Shardlow oa Buglife o itse: "Ho se ho fetile lilemo tse tharo esale re qala ho hatisa kotsi ea phekolo ea matsetse ho liphoofolo tse hlaha, 'me ha ho mehato ea taolo e nkiloeng.Tšilafalo e tebileng le e feteletseng ea fipronil libakeng tsohle tsa metsi ea tšosa, 'me mmuso o hloka ho e thibela ka potlako.Sebelisa fipronil le imidacloprid joalo ka kalafo ea matsetse. ”O boletse hore lithane tse 'maloa tsa likokoanyana tsena li sebelisoa ho liphoofolo tse ruuoang lapeng selemo se seng le se seng.
