I-pest, iSebe laseCalifornia lokutya kunye nezoLimo (CDFA) licinga ukuba "iyona nto imbi kakhulu yemithi yesundu emhlabeni," ifunyenwe kwindawo yaseLaguna Beach, amagosa aseburhulumenteni abhengeze ngo-Oktobha 18. Bathi oku kubonwa okokuqala kwi-weevil ebomvu yesundu (I-Rhynchophorus ferrugineus) eUnited States.
Inambuzane yase-Asia-mpuma ye-Asia isasazeke kwiindawo ezininzi zehlabathi, kuquka i-Afrika, uMbindi Mpuma, iYurophu kunye ne-Oceania. Okona kufunyanisiweyo kukufutshane okuqinisekisiweyo e-United States kwakuse-Dutch Antilles nase-Aruba ngo-2009.
Unokontraka womhlaba okwindawo yaseLaguna Beach waqala waxela ngesihluthu esibomvu sesundu kwabasemagunyeni, sikhuthaza amagosa asekuhlaleni, urhulumente kunye namagosa amanyeneyo ukuba aqinisekise ubukho baso, enze uphando lwendlu ngendlu kwaye abeke imigibe engama-250 ukufumanisa ukuba kukho “uhlaselo” lokwenyani. Abanye bayakhuthazwa ukuba baxele uhlaselo lwabarhanelwa ngokubiza iCDFA Pest Hotline kwi-1-800-491-1899.
Nangona uninzi lwemithi yesundu ingeyonzalelwane yaseCarlifonia, ishishini lomthi wesundu livelisa malunga nezigidi ezingama-70 zeerandi kwiintengiso ngonyaka kwaye abalimi besundu bedate, abafumaneka kwiCoachella Valley, bavuna i-30 yezigidi zeedola ngonyaka.
Nantsi indlela esinokuba yingozi ngayo isitshabalalisi, ichazwe yi-CDFA:
Iimazi ezibomvu zesundu zagqobhozela kumthi wesundu ukuze zenze umngxuma ezizalela kuwo amaqanda. Imazi nganye inokubeka umlinganiselo wamaqanda angama-250, nto leyo ethabatha malunga neentsuku ezintathu ukuqandusela. Imibungu iyavela kunye netonela ukuya ngaphakathi komthi, ithintela amandla omthi ukuthutha amanzi kunye nezondlo eziya phezulu ukuya kwisithsaba. Emva kweenyanga ezimbini zokutyisa, imibungu ihluma ngaphakathi emthini i-avareji yeeveki ezintathu phambi kokuba abadala babomvu-bumdaka. Abantu abadala baphila iinyanga ezimbini ukuya kwezintathu, ngelo xesha batya iintende, bakhwelana izihlandlo ezininzi kwaye babeke amaqanda.
Iinkuku ezikhulileyo zijongwa njengeendiza ezinamandla, zihamba umgama ongaphezu kwesiqingatha semayile zikhangela imithi esiza nayo. Ngokuphindaphindiweyo ngeenqwelomoya kwiintsuku ezintathu ukuya kwezintlanu, kuthiwa ii-weevils ziyakwazi ukuhamba malunga neekhilomitha ezine ezinesiqingatha ukusuka kwindawo yazo yokuqandusela. Zitsaleleka kwimithi yesundu efayo okanye eyonakeleyo, kodwa inokuhlasela nemithi engonakaliswanga. Iimpawu ze-weevil kunye nemingxuma yokungena yombungu kudla ngokuba nzima ukuzibona kuba indawo yokungena inogqunywa ngamahlumelo kunye nemicu yemithi. Ukuhlolwa ngononophelo kweentende ezihlaselweyo kunokubonisa imingxuma kwisithsaba okanye esiqwini, mhlawumbi kunye nolwelo olumdaka oluphumayo kunye nemicu ehlafunwayo. Kwimithi exhaphake kakhulu, iimeko eziwileyo ze-pupal kunye nezinambuzane ezikhulileyo ezifileyo zingafunyanwa emazantsi omthi.
