Ukusetshenziswa kweizibulala-zinambuzaneekhaya kungaba nomthelela omkhulu ekuthuthukisweni kokumelana nomiyane abathwala izifo futhi kunciphise ukusebenza kahle kwemithi yokubulala izinambuzane.
Izazi ze-vector biology ezivela eLiverpool School of Tropical Medicine zishicilele iphepha elikuyi-The Lancet Americas Health eligxile emaphethini okusetshenziswa kwezibulala-zinambuzane zasekhaya emazweni angu-19 lapho izifo ezithwalwa yizinambuzane ezifana nomalaleveva kanye ne-dengue zivame khona.
Nakuba izifundo eziningi zibonise ukuthi izindlela zempilo yomphakathi kanye nokusetshenziswa kwezibulala-zinambuzane kwezolimo kunegalelo kanjani ekuthuthukisweni kokumelana nezibulala-zinambuzane, abalobi balo mbiko bathi ukusetshenziswa kwasekhaya kanye nomthelela wako kusalokhu kungaqondakali kahle. Lokhu kuyiqiniso ikakhulukazi uma kubhekwa ukwanda kokumelana kwezifo ezithwalwa yizinambuzane emhlabeni wonke kanye nosongo ezilubeka empilweni yabantu.
Iphepha eliholwa nguDkt. Fabricio Martins libheka umthelela wezibulala-zinambuzane zasekhaya ekuthuthukisweni kokumelana nezimila ze-Aedes aegypti, besebenzisa iBrazil njengesibonelo. Bathole ukuthi ukuvama kokuguquka kwe-KDR, okubangela ukuthi omiyane be-Aedes aegypti bamelane nezimila ze-pyrethroid (ezivame ukusetshenziswa emikhiqizweni yasekhaya kanye nempilo yomphakathi), kucishe kwaphindeka kabili eminyakeni eyisithupha ngemuva kokuba igciwane le-Zika lilethe izimila zezinambuzane zasekhaya emakethe eBrazil. Izifundo zelebhu zibonise ukuthi cishe amaphesenti ayi-100 omiyane abasinda ekuvezweni kwezimila zezinambuzane zasekhaya babenezinhlobo eziningi zokuguquka kwe-KDR, kanti labo abafa abazange.
Ucwaningo luphinde lwathola ukuthi ukusetshenziswa kwezibulala-zinambuzane zasekhaya kusakazeke kabanzi, cishe abantu abangu-60% abahlala ezindaweni ezingu-19 ezitholakala ezindaweni ezivamile basebenzisa njalo izibulala-zinambuzane zasekhaya ukuze bazivikele.
Bathi ukusetshenziswa okunjalo okungabhalwanga kahle futhi okungalawulwa kunganciphisa ukusebenza kahle kwale mikhiqizo futhi kuthinte nezinyathelo ezibalulekile zezempilo zomphakathi njengokusetshenziswa kwamanethi aphathwe ngezibulala-zinambuzane kanye nokufuthwa kwezibulala-zinambuzane ezisele endlini.
Kudingeka ucwaningo olwengeziwe ukuze kuhlolwe imiphumela eqondile nengaqondile yemithi yokubulala izinambuzane yasekhaya, izingozi nezinzuzo zayo empilweni yabantu, kanye nemiphumela yezinhlelo zokulawula izinambuzane.
Abalobi balo mbiko basikisela ukuthi abenzi bezinqubomgomo bathuthukise isiqondiso esengeziwe mayelana nokuphathwa kwezibulala-zinambuzane zasekhaya ukuqinisekisa ukuthi le mikhiqizo isetshenziswa ngempumelelo nangokuphephile.
UDkt Martins, ocwaningayo kwi-vector biology, uthe: “Lo msebenzi uqhamuke kudatha yasensimini engiyiqoqile ngenkathi ngisebenzisana eduze nemiphakathi eBrazil ukuthola ukuthi kungani omiyane be-Aedes babeqala ukumelana nezifo, ngisho nasezindaweni lapho izinhlelo zezempilo zomphakathi zase ziyeke ukusebenzisa ama-pyrethroids.
"Ithimba lethu landisa ukuhlaziywa kwezifundazwe ezine enyakatho-ntshonalanga yeBrazil ukuze liqonde kangcono ukuthi ukusetshenziswa kwezibulala-zinambuzane zasekhaya kuqhuba kanjani ukukhethwa kwezindlela zofuzo ezihlobene nokumelana ne-pyrethroid."
"Ucwaningo lwesikhathi esizayo mayelana nokumelana phakathi kwezibulala-zinambuzane zasekhaya kanye nemikhiqizo yezempilo yomphakathi luzobaluleka kakhulu ekwenzeni izinqumo ezisekelwe ebufakazini kanye nasekuthuthukisweni kweziqondiso zezinhlelo zokulawula izinambuzane ezisebenzayo."
