CLEMSON, SC – Ukulawula izinambuzane kuyinselele kubakhiqizi abaningi bezinkomo zenyama yenkomo ezweni lonke. Izimpukane ze-Horn (Haematobia irritans) ziyizinambuzane ezivame kakhulu ukulimaza umnotho kubakhiqizi bezinkomo, okubangela ukulahlekelwa kwezomnotho okungu-$1 billion embonini yezilwane yase-US minyaka yonke ngenxa yokukhuluphala, ukulahlekelwa igazi, kanye nokucindezeleka. 1,2 Le ncwadi izosiza abakhiqizi bezinkomo zenyama yenkomo ukuvimbela ukulahlekelwa komkhiqizo okubangelwa yizimpukane ze-horn ezinkomeni.
Izimpukane ze-Hornflies zithatha izinsuku eziyi-10 kuya kwezingama-20 ukukhula kusukela eqandeni kuya esigabeni sobudala, kanti isikhathi sokuphila somdala singamaviki ayi-1 kuya kwayi-2 futhi zondla izikhathi ezingama-20 kuya kwangama-30 ngosuku. 3 Nakuba amathegi ezindlebe afakwe izibulala-zinambuzane enza kube lula ukulawula izimpukane. imigomo yokuphatha, umkhiqizi ngamunye kusadingeka enze izinqumo ezihlobene nokuphathwa kwezimpukane. Kunezinhlobo ezine eziyinhloko zamathegi ezindlebe ezibulala izinambuzane ngokusekelwe ezithakweni zazo ezisebenzayo. Lokhu kufaka phakathi izinambuzane ze-organophosphorus (i-diazinon ne-fenthion), i-synthetic pyrethroids (i-mutton cyhalothrin ne-cyfluthrin), i-abamectin (uhlobo olusha lwelebula), kanye nezintathu zezinambuzane ezisetshenziswa kakhulu. Uhlobo lwesine lwenhlanganisela ye-agent. Izibonelo zokuhlanganiswa kwezibulala-zinambuzane zifaka inhlanganisela ye-organophosphate ne-synthetic pyrethroid noma inhlanganisela ye-synthetic pyrethroid ne-abamectin.
Amathegi okuqala endlebe aqukethwe kuphelaizibulala-zinambuzane ze-pyrethroidfuthi zazisebenza kahle kakhulu. Eminyakeni embalwa nje kamuva, izimpukane ze-horn zaqala ukumelana nemithi yokubulala izinambuzane ye-pyrethroid. Isici esiyinhloko esibangela lokhu ukusetshenziswa kabanzi kanye nokusetshenziswa kabi kwamalebula e-pyrethroid. 4.5 Ukuphathwa kokumelana kufanele kufakwe kunoma yikuphiukulawula izinambuzaneuhlelo, kungakhathaliseki ukuthi umkhiqizo noma indlela yokusebenzisa. Kunezimo zokumelana nezibulala-zinambuzane eziningi ezisetshenziswa ukulawula izimpukane ze-horn, ikakhulukazi i-pyrethroids kanye ne-organophosphate insecticide. INorth Dakota yaba ngeyokuqala ukukhipha izincomo zokusiza ukuvimbela ukuthuthukiswa kwezinhlobo zezimpukane ze-horn ezingamelani nezinambuzane. 6 Izinguquko kulezi zincomo zichazwe ngezansi ukusiza ukulawula ngempumelelo izimpukane ze-horn ngenkathi kuvimbela ukuthuthukiswa kwezinhlobo ezingamelani nezinambuzane.
I-FARGO, ND – Izimpukane zobuso, izimpukane ze-horn kanye nezimpukane ezizinzile yizona zinambuzane ezivame kakhulu futhi eziphathwa kakhulu embonini yezilwane eNorth Dakota. Uma zingalawulwa, lezi zinambuzane zingadala umonakalo omkhulu ekukhiqizweni kwemfuyo. Ngenhlanhla, ochwepheshe be-North Dakota State University Extension bathi amasu okuphatha izinambuzane afanele anganikeza ukulawula okuphumelelayo. Ngenkathi izinambuzane ezihlanganisiwe […]
I-AUBURN UNIVERSITY, e-Alabama. Izimpukane ze-Slingshot zingaba yinkinga enkulu emihlambini yezinkomo ngesikhathi sasehlobo. Izindlela zokulawula izimpukane ezisetshenziswa kakhulu zifaka phakathi ukufafaza, ukukhipha amanzi kanye nokususa uthuli. Kodwa-ke, umkhuba wamuva ekukhiqizweni kwemfuyo ukuthola ezinye izindlela zokulawula izimpukane. Enye indlela eye yathola ukunakwa kwezwe lonke ukusetshenziswa kwegalikhi, isinamoni kanye […]
ILINCOLN, eNebraska. Ekupheleni kuka-Agasti noSepthemba kuvame ukuba yisikhathi lapho isizini yezimpukane zamadlelo kufanele iphele khona. Kodwa-ke, eminyakeni embalwa edlule, ikwindla yethu ibilokhu ifudumele njalo, ngezinye izikhathi iqhubekela ekuqaleni kukaNovemba, futhi izimpukane ziye zahlala emazingeni ayinkinga isikhathi eside kunokujwayelekile. Ngokusho kwezibikezelo zezulu eziningi, ikwindla ezayo ngeke ibe yinto ehlukile. Uma […]
I-MARYVILLE, eKansas. Akukhona nje ukuthi izimpukane ziyacasula, kodwa futhi zingaba yingozi, kungakhathaliseki ukuthi zibangela ukulunywa okubuhlungu okuphazamisa ikhono lehhashi lakho lokugibela, noma zidlulisela izifo emahhashini nasezinkomeni. “Izimpukane ziyaphazamisa futhi kunzima ukuzilawula. Ngokuvamile asikwazi ukuzilawula kahle, simane nje […]
