CLEMSON, SC – Ulawulo lweempukane luyingxaki kubavelisi abaninzi beenkomo zenyama yenkomo kulo lonke ilizwe. Iimpukane zeempondo (iiHaematobia irritans) zezona zinambuzane zixhaphakileyo kwezoqoqosho kubavelisi beenkomo, zibangela ilahleko yezoqoqosho kwishishini lemfuyo lase-US elixabisa i-$1 yezigidigidi ngonyaka ngenxa yokutyeba, ukulahleka kwegazi, kunye noxinzelelo. 1,2 Olu shicilelo luza kunceda abavelisi beenkomo zenyama yenkomo ukuthintela ilahleko yemveliso ebangelwa ziimpukane zeempondo kwiinkomo.
IiHornflies zithatha iintsuku ezili-10 ukuya kwezingama-20 ukukhula ukusuka kwinqanaba leqanda ukuya kwinqanaba lokukhula, kwaye ubomi bomntu omdala bumalunga neveki e-1 ukuya kwezi-2 kwaye wondla amaxesha angama-20 ukuya kuma-30 ngosuku. 3 Nangona iithegi zeendlebe ezifakwe kwizinambuzane zenza kube lula ukulawula iimpukane. iinjongo zolawulo, umvelisi ngamnye kusafuneka enze izigqibo ezinxulumene nolawulo lweempukane. Kukho iintlobo ezine eziphambili zeethegi zeendlebe ezibulala izinambuzane ngokusekelwe kwizithako zazo ezisebenzayo. Ezi ziquka izinambuzane ze-organophosphorus (i-diazinon kunye ne-fenthion), i-synthetic pyrethroids (i-mutton cyhalothrin kunye ne-cyfluthrin), i-abamectin (uhlobo olutsha lweleyibhile), kunye nezintathu zezona zinambuzane zisetyenziswa kakhulu. Uhlobo lwesine lwendibaniselwano yearhente. Imizekelo yendibaniselwano yezinambuzane ibandakanya indibaniselwano ye-organophosphate kunye ne-synthetic pyrethroid okanye indibaniselwano ye-synthetic pyrethroid kunye ne-abamectin.
Iithegi zokuqala zendlebe ziqulathe kuphelaizibulali-zinambuzane ze-pyrethroidkwaye zazisebenza kakuhle kakhulu. Kwiminyaka embalwa kamva, ii-hornflies zaqala ukuxhathisa izinambuzane ze-pyrethroid. Into ephambili enegalelo kukusetyenziswa ngokubanzi kunye nokusetyenziswa gwenxa rhoqo kweelebheli ze-pyrethroid. 4.5 Ulawulo lokuxhathisa kufuneka lufakwe kuyo nayiphi naulawulo lweempukaneinkqubo, nokuba yeyiphi na imveliso okanye indlela esetyenziswa ngayo. Kukho iimeko zokuxhathisa uninzi lwezibulali-zinambuzane ezisetyenziselwa ukulawula iimpondo, ingakumbi ii-pyrethroids kunye nezibulali-zinambuzane ze-organophosphate. INorth Dakota yayiyeyokuqala ukukhupha iingcebiso zokunceda ukuthintela uphuhliso lwamaqela eempondo ezinganyangekiyo. 6 Utshintsho kwezi ngcebiso luchazwe ngezantsi ukunceda ukulawula ngempumelelo iimpondo ngelixa kuthintela uphuhliso lwamaqela eempondo ezinganyangekiyo.
FARGO, ND – Iimpukane zobuso, iimpondo zeempondo kunye neempukane ezizinzileyo zezona zinambuzane zixhaphakileyo neziphathwa kakhulu kwishishini lemfuyo laseNorth Dakota. Ukuba azinakwa, ezi zinambuzane zinokubangela umonakalo omkhulu kwimveliso yemfuyo. Ngethamsanqa, iingcali zoLwandiso lweYunivesithi yaseNorth Dakota State zithi amaqhinga okulawula izinambuzane afanelekileyo anokubonelela ngolawulo olusebenzayo. Ngelixa izinambuzane ezidibeneyo […]
IYUNIVESITHI YASE-AUBURN, e-Alabama. Iimpukane ze-Slingshot zinokuba yingxaki enkulu kwimihlambi yeenkomo ngexesha lasehlotyeni. Iindlela zokulawula iimpukane ezisetyenziswa rhoqo ziquka ukutshiza, ukukhupha uthuli kunye nokufutha uthuli. Nangona kunjalo, umkhwa wakutshanje kwimveliso yemfuyo kukufumana ezinye iindlela zokulawula iimpukane. Enye indlela efumene ingqalelo yesizwe kukusetyenziswa kwegalikhi, isinamoni kunye […]
ILINCOLN, eNebraska. Ekupheleni kuka-Agasti noSeptemba kudla ngokuba lixesha apho ixesha lokubhabha kwamadlelo lifanele liphele. Nangona kunjalo, kwiminyaka embalwa edlulileyo, ukuwa kwethu bekushushu rhoqo, ngamanye amaxesha kudlulela ekuqaleni kukaNovemba, kwaye iimpukane ziye zahlala zinengxaki ixesha elide kunesiqhelo. Ngokwezibikezelo zemozulu ezininzi, ukuwa okuzayo akuyi kuba yinto eyahlukileyo. Ukuba […]
UMARYVILLE, eKansas. Iimpukane azikhathazi nje kuphela, kodwa zinokuba yingozi, nokuba zibangela ukulunywa okubuhlungu okuphazamisa amandla ehashe lakho okukhwela, okanye zidlulisela izifo kumahashe nakwiinkomo. “Iimpukane ziyaphazamisa kwaye kunzima ukuzilawula. Rhoqo asikwazi ukuzilawula ngokufanelekileyo, simane nje […]
