Ubushakashatsi bwerekanye ko udukoko twica udukoko twinshi dukoreshwa mu njangwe n’imbwa mu kwica imbwa zangiza imigezi y’Ubwongereza.Abahanga bavuga ko ivumburwa “rifitanye isano cyane” n’udukoko tw’amazi n’amafi n’inyoni biterwa na byo, kandi biteze ko byangiza cyane ibidukikije.
Ubushakashatsi bwerekanye ko muri 99% by'icyitegererezo kiva mu nzuzi 20, ibirimo fipronil byari byinshi, kandi impuzandengo y'ibicuruzwa byangiza udukoko twangiza udukoko twangiza byikubye inshuro 38 imipaka y’umutekano.Fenoxtone iboneka mu ruzi nundi muti w’imitsi witwa imidacloprid umaze imyaka myinshi bibujijwe mu mirima.
Mu Bwongereza hari imbwa zigera kuri miliyoni 10 n’injangwe miliyoni 11, kandi bivugwa ko 80% by’abantu bazavurwa n’ibihuru (byaba bikenewe cyangwa bidakenewe).Abashakashatsi bavuze ko gukoresha ubuhumyi bwo kuvura fla bidakenewe, kandi hakenewe amabwiriza mashya.Kugeza ubu, kuvura ibihuru byemewe nta gusuzuma ibyangiza ibidukikije.
Rosemary Perkins wo muri kaminuza ya Sussex wari ukuriye ubwo bushakashatsi yagize ati: “Fipronil ni kimwe mu bicuruzwa bikoreshwa cyane.Ubushakashatsi buherutse gukorwa bwerekanye ko bushobora kwangirika ku dukoko twinshi kuruta fipronil ubwayo.Ibintu byinshi byangiza. ”“Ibisubizo byacu biteye impungenge cyane.”
Dave Goulson, umwe mu bagize itsinda ry’ubushakashatsi no muri kaminuza ya Sussex, yagize ati: “sinshobora kwizera neza ko imiti yica udukoko ari rusange.Inzuzi zacu zikunze kwanduzwa niyi miti yombi igihe kirekire..
Yagize ati: “Ikibazo ni uko iyi miti ikora neza,” ndetse no mu bitekerezo bito.Ati: "Turizera ko bizagira ingaruka zikomeye ku buzima bw'udukoko mu ruzi."Yavuze ko umuti wica udukoko ukoresha imidacloprid mu kuvura imbwa mu mbwa ziciriritse bihagije kugira ngo wice inzuki miliyoni 60.
Raporo ya mbere y’urwego rwo hejuru rwa neonicotinoide (nka imidacloprid) mu nzuzi yakozwe nitsinda rishinzwe kubungabunga ibidukikije Buglife mu 2017, nubwo ubushakashatsi butarimo fipronil.Udukoko two mu mazi dushobora kwibasirwa na neonicotinoide.Ubushakashatsi bwakozwe mu Buholandi bwerekanye ko umwanda w’amazi maremare watumye umubare w’udukoko n’inyoni bigabanuka cyane.Bitewe n’indi myanda iva mu mirima n’imyanda, udukoko two mu mazi nabwo turagenda tugabanuka, kandi 14% by’inzuzi zo mu Bwongereza zifite ubuzima bwiza bw’ibidukikije.
Ubushakashatsi bushya bwasohotse mu kinyamakuru cyitwa Comprehensive Environmental Science, bukubiyemo isesengura rigera ku 4000 ry’ingero zegeranijwe n’ikigo cy’ibidukikije mu nzuzi 20 z’Abongereza hagati ya 2016-18.Izi ntera kuva Uruzi rwa Hampshire kugera kuri Edeni muri Cumbria.
Fipronil yagaragaye muri 99% by'icyitegererezo, naho ibicuruzwa byangirika cyane Fipronil sulfone yabonetse muri 97% by'icyitegererezo.Impuzandengo yibanze inshuro 5 ninshuro 38 kurenza urugero rwuburozi bwigihe kirekire.Nta tegeko ribuza iyi miti mu Bwongereza, bityo abahanga bakoresheje raporo y’isuzuma rya 2017 yakorewe mu kigo gishinzwe kugenzura ubuziranenge bw’amazi muri Californiya.Imidacloprid yabonetse muri 66% by'icyitegererezo, kandi uburozi bwarenze inzuzi 7 kuri 20.
Fipronil yabujijwe gukoreshwa mu mirima muri 2017, ariko ntiyakunze gukoreshwa mbere yicyo gihe.Imidacloprid yabujijwe muri 2018 kandi ikoreshwa gake cyane mumyaka yashize.Abashakashatsi basanze urugero rwinshi rw’imiti yica udukoko hepfo y’ibiti bitunganya amazi, byerekana ko imijyi ari isoko nyamukuru, atari imirima.
Nkuko twese tubizi, gukaraba amatungo birashobora kwinjiza fipronil mu miyoboro hanyuma ikinjira mu ruzi, kandi imbwa zoga mu ruzi zitanga ubundi buryo bwo kwanduza.Gulson yagize ati: “Ubu ni bwo buryo bwo kuvura ibihuru byateje umwanda.”Ati: “Mu byukuri, nta yandi masoko yatekerezwa.”
Mu Bwongereza, hari ibikomoka ku matungo 66 byemewe birimo fipronil hamwe n’imiti 21 y’amatungo irimo imidacloprid, inyinshi muri zo zigurishwa nta nyandiko.Hatitawe niba hakenewe kuvurwa ibihuru, inyamanswa nyinshi zivurwa buri kwezi.
Abahanga bavuga ko ibi bigomba gusubirwamo, cyane cyane mu gihe cy'itumba iyo ibihuru bidasanzwe.Bavuze ko hagomba no gusuzumwa amabwiriza mashya, nko gusaba imiti no gusuzuma ingaruka z’ibidukikije mbere yo kwemererwa gukoreshwa.
Gulson yagize ati: "Iyo utangiye gukoresha imiti iyo ari yo yose yica udukoko ku rugero runini, akenshi usanga hari ingaruka zitateganijwe."Biragaragara ko hari ibitagenze neza.Nta buryo bwo kugenzura ibi byago byihariye, kandi biragaragara ko bigomba gukorwa.”
Matt Shardlow wo muri Buglife yagize ati: “Imyaka itatu irashize kuva twatangira gushimangira bwa mbere ingaruka mbi zo kuvura ibihuru ku nyamaswa zo mu gasozi, kandi nta ngamba zafashwe zafashwe.Umwanda ukabije kandi ukabije wa fipronil ku mazi yose aratangaje, kandi leta ikeneye byihutirwa.Koresha fipronil na imidacloprid nk'ubuvuzi bwa fla. ”Yavuze ko buri mwaka toni nyinshi z’udukoko twica udukoko zikoreshwa mu matungo.
