Imiti yica udukoko irwanya imibu irashobora gutandukana cyane mubihe bitandukanye byumunsi, kimwe no kumanywa nijoro. Ubushakashatsi bwakozwe na Floride bwerekanye ko imibu yo mu gasozi Aedes aegypti irwanya permethrine yumvaga cyane kwica udukoko hagati ya saa sita z'ijoro n'izuba rirashe. Kurwanya noneho byariyongereye umunsi wose, mugihe imibu yakoraga cyane, igera nimugoroba nimugoroba nigice cyambere cyijoro.
Ibyavuye mu bushakashatsi bwakozwe n'abashakashatsi bo muri kaminuza ya Florida (UF) bifite ingaruka zikomeye kurikurwanya udukokoabanyamwuga, babemerera gukoresha imiti yica udukoko neza, kuzigama amafaranga, no kugabanya ingaruka z’ibidukikije. Ati: “Twabonye ko dosiye ndende yapermethrinzari zikenewe mu kwica imibu saa kumi n'ebyiri na saa kumi z'umugoroba Aya makuru yerekana ko permethrine ishobora kugira akamaro iyo ikoreshejwe hagati ya saa sita z'ijoro na bucya (saa kumi n'ebyiri za mu gitondo) kuruta nimugoroba (ahagana mu ma saa kumi n'ebyiri z'umugoroba), ”ibi bikaba byavuzwe na Lt. Sierra Schloop, umwe mu banditsi b'ubwo bushakashatsi. Florida hamwe na Eva Buckner, impamyabumenyi y'ikirenga, umwanditsi mukuru w'ubwo bushakashatsi.
Birashobora gusa nkaho byumvikana ko igihe cyiza cyo gukoresha umuti wica udukoko ari mugihe gikunze kuvuza urusaku, guhindagurika, no kuruma, ariko siko buri gihe bigenda, byibuze mubushakashatsi bwakozwe na permethrine, bumwe muribintu bibiri bikoreshwa cyane mu kurwanya udukoko twica udukoko muri Amerika, byakoreshejwe muri ubu bushakashatsi. Umubu wa Aedes aegypti uruma cyane cyane ku manywa, haba mu nzu ndetse no hanze, kandi ukora cyane nyuma yamasaha abiri nyuma yizuba rirashe namasaha make mbere yuko izuba rirenga. Itara ryubukorikori rishobora kwongerera igihe bashobora kumara mu mwijima.
Aedes aegypti (bakunze kwita umubu w’umuhondo w’umuhondo) iboneka ku mugabane wose usibye Antaragitika kandi niwo muti wa virusi zitera chikungunya, dengue, umuriro w’umuhondo, na Zika. Bifitanye isano no kwandura indwara nyinshi zanduye muri Floride.
Icyakora, Schluep yavuze ko ukuri ku bwoko bumwe bw’imibu muri Floride bidashobora kuba ukuri ku tundi turere. Ibintu bitandukanye, nkaho biherereye, birashobora gutuma ibisubizo bikurikirana bya genome byumubu runaka bitandukanye nibya Chihuahuas na Danemarke. Ni yo mpamvu yashimangiye ko ibyavuye mu bushakashatsi bireba gusa umubu w’umuhondo w’umuhondo muri Floride.
Yavuze ko hari ubuvumo bumwe. Ibyavuye muri ubu bushakashatsi birashobora kuba rusange kugirango bidufashe kumva neza abandi baturage b’ubwoko.
Icy'ingenzi cyagaragaye mu bushakashatsi cyerekanye ko ingirabuzimafatizo zimwe na zimwe zitanga imisemburo ya metabolize kandi ikangiza permethrine nayo yagize ingaruka ku mpinduka z’umucyo mu gihe cy’amasaha 24. Ubu bushakashatsi bwibanze ku ngirabuzimafatizo eshanu gusa, ariko ibisubizo birashobora koherezwa mu zindi genes hanze y’ubushakashatsi.
Schluep yagize ati: "Ukurikije ibyo tuzi kuri ubwo buryo ndetse no ku binyabuzima by’umubu, birumvikana ko iki gitekerezo kirenze iyi genes ndetse n’abaturage bo mu gasozi."
Imvugo cyangwa imikorere yiyi genes bitangira kwiyongera nyuma ya saa mbiri zijoro kandi hejuru cyane mu mwijima hagati ya saa kumi n'ebyiri na saa mbiri za mu gitondo Schlup yerekana ko muri gen nyinshi zifite uruhare muri iki gikorwa, ubushakashatsi butanu gusa. Avuga ko ibyo bishobora kuba kubera ko iyo izo gen zikora cyane, uburozi bwiyongera. Imisemburo irashobora kubikwa kugirango ikoreshwe nyuma yumusaruro utinze.
Ati: "Gusobanukirwa neza n’imihindagurikire ya buri munsi mu kurwanya udukoko twica udukoko twahujwe n’imisemburo yangiza muri Aedes aegypti irashobora kwemerera gukoresha imiti yica udukoko mu gihe usanga kwandura ari byinshi kandi ibikorwa by’imisemburo ikabije bikaba bike".

Ed Ricciuti numunyamakuru, umwanditsi, numunyabwenge wandika imyaka irenga igice cyikinyejana. Igitabo aheruka gukora ni Inyuma ya Bear: Inyamaswa nini, Sprawl Sprawl, na New Urban Jungle (Press Country Press, Kamena 2014). Ibirenge bye biri kwisi yose. Azobereye muri kamere, siyanse, kubungabunga, no kubahiriza amategeko. Yigeze kuba umugenzuzi muri Sosiyete Zoologiya ya New York none akora muri Sosiyete ishinzwe kubungabunga inyamaswa. Ashobora kuba umuntu wenyine kumuhanda wa 57 wa Manhattan warumwe na koti.
Umubu wa Aedes scapularis wavumbuwe rimwe gusa, mu 1945 muri Floride. Icyakora, ubushakashatsi bushya bwakozwe ku ngero z’imibu zegeranijwe mu 2020 bwerekanye ko ubu imibu ya Aedes scapularis imaze kwigaragaza mu ntara za Miami-Dade na Broward ku mugabane wa Floride. [Soma birambuye]
Indwara ya conone ikomoka muri Amerika yo Hagati no mu majyepfo kandi iboneka ahantu habiri gusa muri Amerika: Dania Beach na Pompano Beach, Floride. Isesengura rishingiye ku gitsina ry’abaturage bombi ryerekana ko bakomotse ku gitero kimwe. [Soma birambuye]
Nyuma yo kuvumbura ko imibu ishobora kwimuka kure ikoresheje umuyaga muremure, ubushakashatsi burakomeje kwagura amoko n’imiterere y’imibu igira uruhare mu kwimuka kwabo - ibintu byanze bikunze bigorana imbaraga zo gukumira ikwirakwizwa rya malariya n’izindi ndwara ziterwa n’umubu muri Afurika.
