Utshintsho lwexeshana lokuxhathisa izinambuzane kunye nebhayoloji yezilwanyana eziphambili zemalariya, iingcongconi ze-Anopheles, e-Uganda

Ukwandaisibulali-zinambuzaneukuxhathisa kunciphisa ukusebenza kakuhle kolawulo lwevektha. Ukubeka iliso kuxhathisa ivektha kubalulekile ukuqonda inguqu yayo kunye nokuyila iimpendulo ezisebenzayo. Kolu phononongo, sijonge iipatheni zokuxhathisa izinambuzane, ibhayoloji yoluntu lwevektha, kunye notshintsho lwemfuza oluhambelana nokuxhathisa e-Uganda kwixesha leminyaka emithathu ukusuka ngo-2021 ukuya ku-2023. EMayuga, i-Anopheles funestus yayiyeyona ntlobo iphambili, kodwa bekukho ubungqina bokudibanisa nezinye iintlobo ze-An. funestus. Uhlaselo lwe-Sporozoite lwaluphezulu, lufikelele kwi-20.41% ngoMatshi 2022. Ukuxhathisa okunamandla kwabonwa kwi-pyrethroids ngokuphindwe kalishumi kuxilongo lokuxilonga, kodwa ukuthambekela kwafunyanwa kancinci kuvavanyo lwe-PBO synergy.
Imephu yeendawo zokuqokelelwa kweengcongconi kwiSithili saseMayuge. ISithili saseMayuge siboniswe ngombala omdaka. Iilali apho kwaqokelelwa khona ziphawulwe ngeenkwenkwezi eziluhlaza okwesibhakabhaka. Le mephu yenziwe kusetyenziswa isoftware yasimahla nevulelekileyo ye-QGIS version 3.38.
Zonke iingcongconi zigcinwe phantsi kweemeko eziqhelekileyo zokukhulisa iingcongconi: 24–28 °C, 65–85% ukufuma, kunye nexesha lendalo le-12:12 emini. Iingcongconi ezikhula kwiitreyi zeengcongconi zaza zondliwa nge-tetramine ngokukhawuleza. Amanzi eengcongconi ayetshintshwa rhoqo emva kweentsuku ezintathu de kube yi-pupation. Iingcongconi ezindala eziphumayo zagcinwa kwiikheyiji zeBugdom kwaye zondliwa isisombululo seswekile se-10% kangangeentsuku ezi-3–5 ngaphambi kovavanyo lwe-bioassay.
Ukufa kwi-bioassay ye-pyrethroid kwinqanaba le-F1. Ukufa kwamachaphaza eengcongconi ze-Anopheles ezivezwe kwi-pyrethroids zodwa kunye ne-pyrethroids kunye ne-synergists. Iibha zempazamo kwibha kunye neetshathi zekholamu zimele amaxesha okuzithemba asekelwe kwimpazamo eqhelekileyo ye-mean (SEM), kwaye i-NA ibonisa ukuba uvavanyo alwenziwanga. Umgca othe tye onamachaphaza abomvu umele inqanaba lokufa elingama-90% ngaphantsi apho ukumelana kuqinisekiswa khona.
Zonke iiseti zedatha ezenziweyo okanye ezihlalutyiweyo ngeli xesha lophando zifakiwe kwinqaku elipapashweyo kunye neefayile zalo zoLwazi olongezelelweyo.
