Ukusebenza kahle kwama-insecticide ngokumelene nomiyane kungahluka kakhulu ngezikhathi ezahlukene zosuku, kanye naphakathi kwemini nobusuku. Ucwaningo lwaseFlorida lwathola ukuthi omiyane basendle be-Aedes aegypti abamelana ne-permetrin babezwela kakhulu kusibulala-zinambuzane phakathi kwamabili nokuphuma kwelanga. Ukumelana kwabe sekukhula usuku lonke, lapho omiyane besebenza kakhulu, begqama lapho kuhwalala kanye nengxenye yokuqala yobusuku.
Imiphumela yocwaningo olwenziwe ngabacwaningi baseNyuvesi yaseFlorida (UF) inemithelela eminingiukulawula izinambuzaneochwepheshe, okubavumela ukuthi basebenzise izibulala-zinambuzane ngendlela ephumelelayo, bonge imali, futhi banciphise umthelela wabo kwezemvelo. “Sithole ukuthi imithamo ephezulu kakhului-permetrinkwakudingeka ukuze kubulawe omiyane ngo-6 ntambama nango-10 ntambama Le datha iphakamisa ukuthi i-permetrin ingase isebenze kakhulu uma isetshenziswa phakathi kwamabili nasekuseni (6 am) kunakusihlwa (cishe ihora lesi-6 ntambama)," kusho uLt. Sierra Schloop, umbhali ngokubambisana wocwaningo. umfundi ofundela ubudokotela kwi-entomology eNyuvesi yaseFlorida kanye no-Eva Buckner, Ph.D., umbhali omkhulu walolu cwaningo.
Kungase kubonakale kuwumqondo ophusile ukuthi isikhathi esingcono kakhulu sokufaka isibulala-zinambuzane komiyane yilapho bevame ukubhuza, baphaphazele, futhi balume, kodwa akunjalo ngaso sonke isikhathi, okungenani ekuhlolweni kwe-permethrin, okukodwa kwezibulala-zinambuzane ezimbili ezisetshenziswa kakhulu e-United States, eyasetshenziswa kulolu cwaningo. Umiyane we-Aedes aegypti uluma ikakhulukazi phakathi nosuku, ngaphakathi nangaphandle, futhi usebenza kakhulu cishe amahora amabili ngemva kokuphuma kwelanga namahora ambalwa ngaphambi kokushona kwelanga. Ukukhanya okwenziwayo kungandisa isikhathi abangasichitha ebumnyameni.
I-Aedes aegypti (evame ukwaziwa ngokuthi umiyane we-yellow fever) itholakala kuwo wonke amazwekazi ngaphandle kwe-Antarctica futhi iyi-vector yamagciwane abangela i-chikungunya, udenga, i-yellow fever, ne-Zika. Kuye kwaxhunyaniswa nokuqubuka kwezifo eziningana ezihlala njalo eFlorida.
Nokho, u-Schluep waphawula ukuthi okuyiqiniso ohlotsheni olulodwa lomiyane eFlorida kungase kungabi yiqiniso kwezinye izifunda. Izinto ezihlukile, njengendawo yendawo, zingabangela imiphumela yokulandelana kofuzo yomiyane othile ukuthi ihluke kuleyo yama-Chihuahuas nama-Great Danes. Ngakho-ke, ugcizelele ukuthi, okutholwe kulolu cwaningo kusebenza kuphela omiyane be-yellow fever eFlorida.
Kukhona i-caveat eyodwa, nokho, uthe. Okutholwe kulolu cwaningo kungenziwa jikelele ukuze usisize siqonde kangcono ezinye izinhlobo zezinhlobo zezilwane.
Ukuthola okubalulekile kocwaningo kubonise ukuthi izakhi zofuzo ezithile ezikhiqiza ama-enzyme agaya futhi akhiphe i-permetrin nawo athinteke ekushintsheni kokukhanya kokukhanya esikhathini esingamahora angama-24. Lolu cwaningo lugxile ezakhini zofuzo ezinhlanu kuphela, kodwa imiphumela ingadluliselwa kwezinye izakhi zofuzo ngaphandle kocwaningo.
"Uma sibheka esikwaziyo ngalezi zindlela kanye nesayensi yezinto eziphilayo zomiyane, kunengqondo ukwelula lo mbono ngale kwalezi zakhi zofuzo kanye nalesi sibalo sasendle," kusho uSchluep.
Inkulumo noma ukusebenza kwalezi zakhi zofuzo kuqala ukwanda ngemva kwehora lesibili ntambama futhi ifinyelela phezulu ebumnyameni phakathi kuka-6pm no-2 am Schlup uveza ukuthi ezakhini zofuzo eziningi ezihilelekile kule nqubo, ezinhlanu kuphela ezihlolisisiwe. Uthi lokhu kungenzeka kungenxa yokuthi uma lezi zakhi zofuzo zisebenza kanzima, ukuqeda ubuthi kuyathuthukiswa. Ama-enzyme angagcinwa ukuze asetshenziswe ngemuva kokuncipha kokukhiqizwa kwawo.
"Ukuqonda kangcono ukuhluka kwe-diurnal ekuphikisweni kwezinambuzane okuqondiswa ama-enzyme e-detoxification e-Aedes aegypti kungase kuvumele ukusetshenziswa okuhlosiwe kwama-insecticides ngezikhathi lapho ukuthambekela kuphezulu kakhulu futhi umsebenzi we-enzyme ye-detoxification uphansi kakhulu," esho.
"Izinguquko ze-Diurnal ekuzweleni kwe-permethrin kanye nokubonakaliswa kwezakhi zofuzo ku-Aedes aegypti (Diptera: Culicidae) eFlorida"
U-Ed Ricciuti uyintatheli, umbhali, kanye nesazi semvelo osekuphele iminyaka engaphezu kwesigamu sekhulu ebhala. Incwadi yakhe yakamuva ithi Backyard Bears: Big Animals, Suburban Sprawl, kanye neNew Urban Jungle (Countryman Press, June 2014). Izinyathelo zakhe zisemhlabeni wonke. Ugxile kakhulu kwezemvelo, isayensi, ukongiwa kwemvelo, kanye nokugcinwa komthetho. Wake waba ngumqaphi e-New York Zoological Society futhi manje usebenzela i-Wildlife Conservation Society. Kungenzeka kube nguye yedwa umuntu oseManhattan's 57th Street oke walunywa yijazi.
Omiyane be-Aedes scapularis batholwe kanye kuphela, ngo-1945 eFlorida. Kodwa-ke, ucwaningo olusha lwamasampula omiyane oluqoqwe ngo-2020 lwathola ukuthi omiyane be-Aedes scapularis sebezisungule ezindaweni zaseMiami-Dade naseBroward ezweni laseFlorida. [Funda kabanzi]
Imihlwa enamakhanda ekhanda ivela eMelika Ephakathi naseNingizimu futhi itholakala ezindaweni ezimbili kuphela e-United States: i-Dania Beach nePompano Beach, eFlorida. Ukuhlaziywa kofuzo okusha kwalezi zizwe ezimbili kuphakamisa ukuthi zisuka ekuhlaselweni okufanayo. [Funda kabanzi]
Ukulandela ukutholakala kokuthi omiyane bangafuduka amabanga amade besebenzisa imimoya ephezulu, ucwaningo olwengeziwe lwandisa izinhlobo nezinhlobonhlobo zomiyane abathintekayo ekufudukeni okunjalo - izici eziqinisekile ukuthi zizokwenza kube nzima imizamo yokunqanda ukusabalala kwe-malaria nezinye izifo ezithwalwa omiyane e-Afrika.
