Mambure ane mishonga yekuuraya zvipembenene (Insecticide-treated bed nets) (ITNs) ndiwo anonyanya kushanda uye anoshandiswa zvakanyanya kudzivirira malaria.Vave vachiratidzwa kakawanda kuti vaderedze chirwere chemalaria uye kufa mukuedza uye zvirongwa zvepurogiramu uye vakaita mupiro mukuru pane chero ipi zvayo ichangobva kupindira kuderedza chirwere chemalaria.Zvisinei, kuvimba kwavo neboka rimwe remishonga inouraya zvipembenene (pyrethroids) kunoita kuti pasave nesimba, zvichikurudzira kupararira kwepyrethroid resistance mumavector emarariya.Pakati pa2010 na2020, kuramba kwepyrethroid kwakaonekwa mune ingangoita imwe vheji mhando mu88% yenyika dzine marariya.Kunyange zvazvo zvidzidzo zvakaratidza kuti mambure ane mishonga yezvipembenene anodzivirira pamarariya pasinei nekurwisa, pane humbowo hwakasimba hwekuti umhutu hunowanikwa mumambure ane pyrethroid hwakavandudza kurarama uye kudya.Tichifunga nezvekukosha kwazvo pakudzivirira nekudzora marariya, chero kumwe kudzikiswa kwekushanda kwemambure ane mishonga yezvipembenene kunogona kukonzera kutangazve kwezvirwere uye kufa.
Mukudavidza kutyisidzira uku, mambure ane maviri-anoshanda ane mishonga yezvipembenene, ayo anobatanidza pyrethroid nemumwe musanganiswa, akagadzirwa kuti adzorere kudzora kwemalariya anodzivirira pyrethroid.Yekutanga mhando nyowani yeITN inosanganisa pyrethroids nePIPERONYL BUTOXIDE (PBO), synergist inowedzera kushanda kwepyrethroids nekuita neutralizing detoxifying enzymes inobatanidza nepyrethroid resistance10.Mudzimba dzekuyedza uye cluster randomized controlled trials (cRCT) ITNs dzine pyrethroids nePBO dzakaratidza hukuru hweentomological mabhenefiti zvichienzaniswa neITNs dzine chete pyrethroids uye epidemiological efficacy.Kubva ipapo vakagamuchira kurudziro yeWHO yekugovera munzvimbo idzo mavekita anoratidza kuramba kune pyrethroids, zvichikonzera kuwedzera kukuru kwekuparadzirwa kwavo munyika dzine dambudziko mumakore achangopfuura18.Nekudaro, iyo pyrethroid-PBO ITN haina miganhu.Zvinonzwisisika, pane kushushikana pamusoro pekusimba kwavo mushure mekushandisa kwenguva refu pamba.Zvidzidzo zvevatyairi muWest Africa zvinoratidzawo kuti pyrethroid-PBO mosquito nets inogona kupa bhenefiti shoma munzvimbo dzine kuwedzera kwekudzivirira kwepyrethroid kunoyananiswa nemaitiro akaomarara uye akawanda.Nokudaro, kuitira kutonga kwevector kunoshanda uye kwakasimba, zvakakosha kushandisa mamwe marudzi emambure ane mishonga yezvipembenene, zvichida ane mamwe mishonga mitsva iyo mavector anonzwa.
