Kafukufuku watsopano wokhudza kuchuluka kwa nsikidzi (Cimex lectularius) adapeza kuti anthu ena sakhudzidwa kwambiri ndi mankhwala awiri omwe amagwiritsidwa ntchito kwambiri.
Akatswiri othana ndi tizirombo ndi anzeru polimbana ndi mliri womwe ukupitilirabe wa nsikidzi chifukwa atengera njira zambiri zochepetsera kudalira kwawo kugwiritsa ntchito mankhwala, chifukwa kafukufuku watsopano akuwonetsa kuti nsikidzi zimagonjetsedwa ndi mankhwala awiri omwe amagwiritsidwa ntchito kwambiri.Zizindikiro zoyambirira.
Pakafukufuku yemwe adasindikizidwa sabata ino mu Journal of Economic Entomology, ofufuza pa Yunivesite ya Purdue adapeza kuti mwa anthu 10 a nsikidzi omwe amasonkhanitsidwa m'munda, anthu atatu amakhudzidwa ndi chlorpheniramine.Kukhudzidwa kwa anthu a 5 ku bifenthrin kunachepanso.
Nsikidzi wamba (Cimex lectularius) yawonetsa kukana kwambiri kwa deltamethrin ndi mankhwala ena ophera tizilombo a pyrethroid, omwe akukhulupirira kuti ndiye chifukwa chachikulu chakuyambiranso ngati tizilombo ta mtawuni.Ndipotu, malinga ndi kafukufuku wa 2015 Pest without Borders wochitidwa ndi National Association for Pest Management ndi University of Kentucky, 68% ya akatswiri osamalira tizilombo amaona kuti nsikidzi ndizovuta kwambiri kuziletsa.Komabe, palibe kafukufuku yemwe wachitika kuti afufuze zomwe zingatheke kukana bifenthrin (komanso pyrethroids) kapena clofenazep (mankhwala ophera tizilombo), zomwe zinapangitsa ofufuza a University of Purdue kuti afufuze.
“M’mbuyomu, nsikidzi zasonyeza mobwerezabwereza kuti zimatha kukana mankhwala omwe amadalira kwambiri mphamvu zawo.Zomwe apeza pa kafukufukuyu zikuwonetsanso kuti nsikidzi zili ndi machitidwe ofanana pakukula kwa kukana clofenazep ndi bifenthrin.Zomwe zapezazi komanso momwe zimakhalira ndi mankhwala ophera tizilombo, bifenthrin ndi chlorpheniramine ziyenera kugwiritsidwa ntchito pamodzi ndi njira zina zochotseratu nsikidzi kuti zikhalebe zogwira mtima kwa nthawi yaitali.”
Adayesa kuchuluka kwa nsikidzi zokwana 10 zomwe zidasonkhanitsidwa ndikuthandizidwa ndi akatswiri osamalira tizilombo komanso ofufuza apayunivesite ku Indiana, New Jersey, Ohio, Tennessee, Virginia ndi Washington DC, ndipo anayeza nsikidzi zomwe zidaphedwa ndi nsikidzizi mkati mwa masiku 7 atawonekera.peresenti.Mankhwala ophera tizilombo.Nthawi zambiri, potengera kusanthula komwe kunachitika, poyerekeza ndi kuchuluka kwa anthu opezeka m'ma labotale, kuchuluka kwa nsikidzi zopitilira 25% kumawonedwa kuti sikungathe kugwidwa ndi mankhwala ophera tizilombo.
Chochititsa chidwi n'chakuti ochita kafukufuku anapeza mgwirizano pakati pa clofenazide ndi bifenthrin susceptibility pakati pa anthu a nsikidzi, zomwe zinali zosayembekezereka chifukwa mankhwala awiriwa amagwira ntchito mosiyana.Gundalka adati kafukufuku wina akufunika kuti amvetsetse chifukwa chake nsikidzi zomwe sizingatengeke pang'ono zimatha kupirira kukhudzana ndi mankhwalawa, makamaka clofenac.Mulimonse momwe zingakhalire, kutsata njira zophatikizira zowononga tizilombo kumachepetsa kukula kwa kukana.
