I-CLEMSON, SC – Ulawulo lweempukane lucelomngeni kubavelisi abaninzi beenkomo zenyama kulo lonke ilizwe.Iimpukane zeempondo (iHaematobia irritans) zezona zinambuzane zixhaphakileyo kwezoqoqosho kubavelisi beenkomo, ezibangela i-1 yeebhiliyoni zeerandi kwilahleko yezoqoqosho kwishishini lemfuyo yase-US ngonyaka ngenxa yokufumana ubunzima, ukulahleka kwegazi kunye noxinzelelo.inkunzi yenkomo.1,2 Olu papasho luza kunceda abavelisi beenkomo zenyama ukuba bathintele ilahleko yemveliso ebangelwa ziimpukane ezikwiinkomo.
Iimpukane zithatha iintsuku ezilishumi ukuya kweziyi-20 ukukhula ukusuka kwiqanda ukuya kwinqanaba labantu abadala, kwaye ubomi babantu abadala bumalunga neveki enye ukuya kwezi-2 kwaye zondla amaxesha angama-20 ukuya kwangama-30 ngosuku.3 Nangona iithegi zendlebe ezifakelwe ngamayeza ezinambuzane zikwenza lula ukulawula iimpukane.iinjongo zolawulo, umvelisi ngamnye kusafuneka enze izigqibo ezinxulumene nolawulo lweempukane.Kukho iintlobo ezine eziphambili zeethegi zendlebe ze-insecticidal ngokusekelwe kwizithako ezisebenzayo.Ezi ziquka izibulali-zinambuzane ze-organophosphorus (i-diazinon kunye ne-fenthion), i-synthetic pyrethroids (i-mutton cyhalothrin kunye ne-cyfluthrin), i-abamectin (uhlobo olutsha lweleyibhile), kunye nezintathu zezona zibulala izitshabalalisi ezisetyenziswa ngokuqhelekileyo.Uhlobo lwesine lokudibanisa i-arhente.Imizekelo yendibaniselwano yesibulali zinambuzane ibandakanya indibaniselwano ye-organophosphate kunye ne-synthetic pyrethroid okanye indibaniselwano ye-synthetic pyrethroid kunye ne-abamectin.
Iithegi zokuqala zendlebe ziqulathe kuphelaamayeza e-pyrethroidkwaye zasebenza kakhulu.Kwiminyaka nje embalwa kamva, iimpukane zaqalisa ukuxhathisa amayeza okubulala izinambuzane epyrethroid.Eyona nto inegalelo kukusetyenziswa okuxhaphakileyo kunye nokusetyenziswa kakubi kweelebhile zepyrethroid.4.5 Ulawulo lokumelana kufuneka lubandakanywe kuyo nayiphi naulawulo lweempukaneinkqubo, nokuba yeyiphi na imveliso okanye indlela yokusetyenziswa.Kukho iimeko zokuchasana nezininzi zezinambuzane ezisetyenziselwa ukulawula iimpukane zeempondo, ngakumbi i-pyrethroids kunye ne-organophosphate insecticide.INorth Dakota yaba yeyokuqala ukukhupha iingcebiso zokunceda ukuthintela ukukhula kweempukane ezikwaziyo ukumelana namayeza.6 Utshintsho kwezi ngcebiso luchazwe ngezantsi ukunceda ukulawula ngokufanelekileyo iimpukane ngelixa kuthintelwa ukuphuhliswa kwabemi abaxhathisa amayeza okubulala izinambuzane.
I-FARGO, ND – Iimpukane zobuso, iimpukane zophondo kunye neempukane ezizinzileyo zezona zinambuzane zixhaphakileyo kwaye zixhaphake ukunyangwa kwishishini lemfuyo laseNorth Dakota.Ukuba azikhange ziqwalaselwe, ezi zinambuzane zinokubangela umonakalo omkhulu kwimveliso yemfuyo.Ngethamsanqa, iingcali zoLwandiso lweYunivesithi yaseNorth Dakota State zithi iindlela ezifanelekileyo zokulawula izinambuzane ezinokubonelela ngolawulo olusebenzayo.Ngelixa isitshabalalisi esidibeneyo […]
