Ukusetyenziswa kweizibulali-zinambuzaneekhaya kunokuba nefuthe elikhulu ekuphuhlisweni kokuxhathisa kwiingcongconi ezithwala izifo kwaye kunciphise ukusebenza kakuhle kwezibulali-zinambuzane.
Iingcali zebhayoloji zezilwanyana ezivela kwiLiverpool School of Tropical Medicine zipapashe iphepha kwiThe Lancet Americas Health eligxile kwiipatheni zokusetyenziswa kwezibulali-zinambuzane zasekhaya kumazwe ali-19 apho izifo ezithwalwa zizinambuzane ezifana nemalariya kunye nedengue zixhaphake khona.
Nangona uphando oluninzi lubonise indlela amanyathelo empilo yoluntu kunye nokusetyenziswa kwezibulali-zinambuzane kwezolimo okunegalelo ngayo ekuphuhlisweni kokuchasana nezibulali-zinambuzane, ababhali bengxelo bathi ukusetyenziswa kwamakhaya kunye nempembelelo yako akukaqondwa kakuhle. Oku kuyinyani ngakumbi xa kujongwa ukwanda kokuchasana kwezifo ezithwalwa zizinambuzane kwihlabathi liphela kunye nosongelo lwazo kwimpilo yoluntu.
Iphepha elikhokelwa nguGqr. Fabricio Martins lijonge impembelelo yezibulali-zinambuzane zasekhaya ekuphuhliseni ukuxhathisa kwiingcongconi ze-Aedes aegypti, besebenzisa iBrazil njengomzekelo. Bafumanise ukuba ukuphindaphindeka kotshintsho lwe-KDR, olubangela ukuba iingcongconi ze-Aedes aegypti zingabi namandla okumelana nezibulali-zinambuzane ze-pyrethroid (ezisetyenziswa rhoqo kwiimveliso zasekhaya nakwimpilo yoluntu), kuphantse kwaphindeka kabini kwiminyaka emithandathu emva kokuba intsholongwane yeZika ingenise izibulali-zinambuzane zasekhaya kwimarike eBrazil. Izifundo zelebhu zibonise ukuba phantse i-100 ekhulwini leengcongconi ezasinda ekuchatshazelweni zizibulali-zinambuzane zasekhaya zazine-KDR ezininzi ezitshintshileyo, ngelixa ezo zafayo zazingenawo.
Olu phononongo lukwafumanise ukuba ukusetyenziswa kwezibulali-zinambuzane zasekhaya kuxhaphakile, malunga nama-60% abemi kwiindawo ezili-19 ezifumanekayo basebenzisa rhoqo izibulali-zinambuzane zasekhaya ukuzikhusela.
Bathi ukusetyenziswa okungabhalwanga kakuhle nokungalawulwayo okunjalo kunokunciphisa ukusebenza kwezi mveliso kwaye kuchaphazele neendlela eziphambili zempilo yoluntu ezifana nokusetyenziswa kweenethi ezinyangiweyo kunye nokutshiza izibulali-zinambuzane ezisele ngaphakathi.
Kufuneka uphando olongezelelekileyo ukuze kuhlolwe imiphumo ethe ngqo nengathanga ngqo yezinambuzane zasekhaya, iingozi kunye neenzuzo zazo kwimpilo yabantu, kunye nemiphumo kwiinkqubo zokulawula iintsholongwane.
Ababhali bale ngxelo bacebisa ukuba abenzi bomgaqo-nkqubo baphuhlise isikhokelo esongezelelweyo malunga nolawulo lwezinambuzane zasekhaya ukuqinisekisa ukuba ezi mveliso zisetyenziswa ngokufanelekileyo nangokukhuselekileyo.
UGqr. Martins, umphandi kwi-vector biology, uthe: “Le projekthi ivele kwidatha yasentsimini endiyiqokeleleyo ngelixa ndisebenza ngokusondeleyo noluntu lwaseBrazil ukufumanisa ukuba kutheni iingcongconi ze-Aedes zikhula zingakwazi ukumelana nezifo, nakwiindawo apho iinkqubo zempilo yoluntu ziye zayeka ukusebenzisa i-pyrethroids.
Iqela lethu liyandisa olu hlalutyo kumazwe amane kumantla ntshona eBrazil ukuze liqonde ngcono indlela ukusetyenziswa kwezibulali-zinambuzane emakhaya okuqhuba ngayo ukukhethwa kweendlela zemfuza ezinxulumene nokuxhathisa i-pyrethroid.
"Uphando lwexesha elizayo malunga nokuchasana phakathi kwezibulali-zinambuzane zasekhaya kunye neemveliso zempilo yoluntu luya kuba luncedo kakhulu ekwenzeni izigqibo ezisekelwe kubungqina kunye nophuhliso lwezikhokelo zeenkqubo zokulawula iintsholongwane ezisebenzayo."
