IREDFIELD, eIowa (DTN) – Iimpukane zinokuba yingxaki kwimihlambi yeenkomo ngexesha lentwasahlobo nehlobo. Ukusebenzisa ulawulo olufanelekileyo ngexesha elifanelekileyo kunokunceda ekufumaneni imbuyekezo kutyalo-mali.
“Iindlela ezilungileyo zokulawula izinambuzane zinokunceda ekuboneleleni ngolawulo olusebenzayo,” utshilo uGerald Stokka, ugqirha wezilwanyana kunye nengcali yolawulo lwemfuyo kwiYunivesithi yaseNorth Dakota State. Oku kuthetha ulawulo olufanelekileyo ngexesha elifanelekileyo nangexesha elifanelekileyo.
“Xa kukhuliswa amathole enkomo, ulawulo lwezinambuzane ezitya iintwala neempukane ngaphambi kokuba zityiwe aluyi kusebenza kwaye luphumela ekulahlekelweni kwezixhobo zokulawula izinambuzane,” utshilo uStoica. “Ixesha kunye nohlobo lolawulo lwezinambuzane luxhomekeke kuhlobo lweempukane.”
IiHornflies kunye neeseaflies zihlala zingaveli kude kube sekuqaleni kwehlobo kwaye azifikeleli kumda wezoqoqosho wokulawula kude kube phakathi kwehlobo. IiHornflies zingwevu kwaye zibukeka njengee-small house fly. Ukuba azithintelwanga, zinokuhlasela imfuyo ukuya kuthi ga kwi-120,000 amaxesha ngosuku. Ngexesha lexesha elixakekileyo, ukuya kuthi ga kwi-4,000 slingshot flies zingaphila kwisikhumba senkomo esinye.
UElizabeth Belew, ingcali yesondlo seenkomo kwiPurina Animal Nutrition, uthe iimpukane ezirhuqwayo ziphela zinokubiza imboni yemfuyo yaseMelika ukuya kuthi ga kwi-1 yeebhiliyoni zeerandi ngonyaka. “Ukulawula iimpukane zeenkomo kwasekuqaleni kwexesha lonyaka kunokwenza umahluko omkhulu ekulawuleni inani lazo kulo lonke ixesha lonyaka,” utshilo.
“Ukuluma rhoqo kunokubangela iintlungu noxinzelelo kwiinkomo kwaye kunokunciphisa ubunzima benkomo ngeekhilogram ezingama-20,” wongezelela uStokka.
Iimpukane ezibonakala ngathi ziimpukane ezinkulu, ezimnyama. Ziimpukane ezingalumiyo ezitya indle yezilwanyana, i-nectar yezityalo kunye nolwelo lwendle. Ezi mpukane zinokosulela amehlo eenkomo kwaye zibangele i-conjunctivitis. Ezi mpukane zihlala zifikelela kwincopho ekupheleni kwehlobo.
Iimpukane ezizinzileyo ziyafana ngobukhulu neempukane zasekhaya, kodwa zineempawu ezingqukuva ezizahlula kwiimpukane zeempondo. Ezi mpukane zitya igazi, zihlala ziluma isisu nemilenze. Kunzima ukuzilawula ngeemveliso ezichithekileyo okanye ezifakwe inaliti.
Kukho iintlobo ezahlukeneyo zolawulo lokubhabha, kwaye ezinye zinokusebenza ngcono kunezinye kwiimeko ezithile. Ngokutsho kukaBelew, indlela esebenzayo nelula yokulawula iimpukane zeempondo kulo lonke ixesha lokubhabha kukutya iiminerali eziqulethe izinambuzane ezilawula ukukhula kwazo (ii-IGR), ezifanelekileyo kuzo zonke iindidi zeenkomo.
“Xa iinkomo ezine-IGR zisitya le minerali, idlula kwisilwanyana ize ingene kwindle entsha, apho iimpukane zeempondo zemazi ezindala zibeka amaqanda. I-IGR ithintela iipupae ukuba zingakhuli zibe ziimpukane ezindala ezilumayo,” ucacisa. Kungcono ukondla iintsuku ezingama-30 ngaphambi kweqabaka lokugqibela entwasahlobo kunye neentsuku ezingama-30 emva kweqabaka lokuqala ekwindla ukuqinisekisa ukuba ukutya kwemfuyo kufikelela kumanqanaba ekujoliswe kuwo.
UColin Tobin, isazinzulu sezilwanyana kwiZiko loPhando lweCarrington le-NDSU, uthe kuluncedo ukuhlola amadlelo ukuze kuchongwe ukuba zeziphi iimpukane ezikhoyo kunye nenani lazo. Iithegi zeendlebe, eziqulethe izibulali-zinambuzane ezikhutshwa kancinci kancinci eboyeni besilwanyana njengoko sihamba, ziyindlela elungileyo, kodwa akufuneki zisetyenziswe de inani leempukane libe phezulu phakathi kuJuni ukuya kuJulayi, utshilo.
Ucebisa ukuba kufundwe iilebheli, njengoko iilebheli ezahlukeneyo zinokwahluka ngokwemilinganiselo yokusetyenziswa, ubudala beenkomo obunokuthi buchazwe, kunye nomgangatho weekhemikhali wesithako esisebenzayo. Iilebheli mazisuswe xa zingasasebenzi.
Olunye ukhetho lokulawula kukufaka iikhompawundi kwiimbiza kunye nezitshizi zezilwanyana. Zidla ngokusetyenziswa ngqo kumgca ophezulu wesilwanyana. Le khemikhali iyafunxwa kwaye ijikeleze umzimba wonke wesilwanyana. La mayeza anokulawula iimpukane kangangeentsuku ezingama-30 ngaphambi kokuba ziphinde zisetyenziswe.
“Ukuze kulawulwe iimpukane ngendlela efanelekileyo, kufuneka kusetyenziswe izitshizi rhoqo kwiiveki ezimbini ukuya kwezintathu kulo lonke ixesha lokubhabha,” utshilo uTobin.
Kwiimeko zokusetyenziswa ngenkani, iindlela zokulawula iimpukane ezisebenzayo kakhulu ziziqokeleli zothuli, izicoci zangasemva kunye neetini zeoyile. Zifanele zibekwe kwiindawo apho imfuyo inokufikelela rhoqo khona, njengemithombo yamanzi okanye iindawo zokutya. Umgubo okanye ulwelo lusetyenziswa njengesibulali-zinambuzane. UBellew ulumkisa ukuba oku kufuna ukuhlolwa rhoqo kwezixhobo zokugcina izibulali-zinambuzane. Nje ukuba iinkomo ziqaphele ukuba ziyanceda, ziya kuqala ukusebenzisa ezi zixhobo rhoqo, utshilo.
