Kushandisa mishonga yezvipembenene kumba kunogona kukonzera kusamira kweumhutu, chirevo chinodaro

Kushandiswa kwemishonga yezvipembenenemumba inogona kuita zvakakosha pakukura kwekupikisa muhutu hunotakura zvirwere uye kuderedza kushanda kwezvipembenene.
Vector biologist kubva kuLiverpool Chikoro cheTropical Medicine vakaburitsa bepa muThe Lancet Americas Health vachitarisa maitiro ekushandiswa kwezvipembenene mudzimba munyika gumi nepfumbamwe umo zvirwere zvinotapuriranwa nemavheji zvakaita semarariya nedengue.
Nepo ongororo dzakawanda dzakaratidza kuti matanho ehutano hweveruzhinji pamwe nekushandiswa kwemishonga yezvipembenene zvekurima zvinobatsira sei mukusimudzira kurwisa zvipembenene, vanyori vemushumo uyu vanopokana kuti mashandisirwo emumba nemabatiro azvo zvinoramba zvisinganzwisisike. Izvi ndezvechokwadi kunyanya kupiwa kuramba kuri kuramba kwezvirwere zvinotapurirwa nevector pasi rese uye kutyisidzira kwavanoita kuhutano hwevanhu.
Pepa rinotungamirirwa naDr Fabricio Martins rinotarisa kukanganiswa kwezvipembenene zvemumba pakukura kwekupikisa muAedes aegypti mosquitoes, vachishandisa Brazil semuenzaniso. Vakaona kuti kuwanda kweKDR mutations, izvo zvinoita kuti Aedes aegypti mosquito dzisagadzirike kune pyrethroid insecticides (inowanzo shandiswa muzvigadzirwa zvemumba uye hutano hweveruzhinji), yakapetwa kaviri mumakore matanhatu mushure mekunge Zika virus yaunza mishonga yemumba kumusika muBrazil. Ongororo dzemurabhoritari dzakaratidza kuti ingangoita zana muzana yeumhutu hwakapona pakusangana nemishonga inouraya zvipembenene yemumba hwakatakura kuchinja kweKDR kwakawanda, nepo dziya dzakafa hadzina.
Ongororo iyi yakawanawo kuti kushandiswa kwemishonga yezvipembenene yemumba kwakapararira, uye vangangoita 60% yevagari munzvimbo gumi nepfumbamwe dzinogara dzichishandisa mishonga yemumba yekuzvidzivirira.
Vanoti kushandiswa kusina kunyorwa zvakanaka uye kusiri pamutemo kunogona kuderedza kushanda kwezvigadzirwa izvi uye zvakare kukanganisa matanho akakosha ehutano hweveruzhinji sekushandisa mambure ane mishonga yekuuraya zvipembenene uye kumwaya mudzimba kwasara kwemishonga yezvipembenene.
Imwe tsvagiridzo inodiwa kuti tiongorore zvakanangana uye zvisina kunanga mhedzisiro yezvipembenene zvemumba, njodzi dzadzo uye mabhenefiti kuhutano hwevanhu, uye zvinokonzeresa zvirongwa zvekudzivirira mavheji.
Vanyori vemushumo uyu vanokurudzira kuti vanogadzira mitemo vanogadzira imwe nhungamiro pakutonga kwemishonga yezvipembenene mudzimba kuitira kuti zvigadzirwa izvi zvishandiswe nemazvo uye zvisina njodzi.
Dr Martins, mumwe muongorori wevector biology, akati: "Chirongwa ichi chakakura kubva kune data remumunda randakaunganidza ndichishanda pamwe nenharaunda muBrazil kuti ndione kuti sei Umhutu hweAedes hwairamba huchiramba, kunyangwe munzvimbo idzo zvirongwa zvehutano zveveruzhinji zvakamira kushandisa pyrethroids.
"Chikwata chedu chiri kuwedzera ongororo kumatunhu mana kuchamhembe kwakadziva kumadokero kweBrazil kuti tinzwisise zviri nani mashandisirwo emushonga wezvipembenene emumba anotungamira kusarudzwa kwemajini ane chekuita nepyrethroid resistance.
"Kutsvagisa kweramangwana pamusoro pekupokana pakati pezvipembenene zvemumba uye zvigadzirwa zvehutano zveveruzhinji kuchave kwakakosha pakuita sarudzo-kwakavakirwa pakuita sarudzo uye kuvandudza nhungamiro yezvirongwa zvinobudirira zvekudzivirira mavheji."
