Isilokazane, uMnyango Wezokudla Nezolimo waseCalifornia (CDFA) esibheka “njengesilokazane esibi kakhulu sezihlahla zesundu emhlabeni,” siye satholakala endaweni yaseLaguna Beach, izikhulu zezwe zamemezela ngo-October 18. Bathi lesi esokuqala- ukutholwa njalo kwe-red palm weevil (I-Rhynchophorus ferrugineus) e-United States.
Isinambuzane somdabu saseNingizimu-mpumalanga ye-Asia sesisabalele emhlabeni wonke, okuhlanganisa i-Afrika, Middle East, Europe kanye ne-Oceania. Ukutholwa okuseduze okuqinisekisiwe okuya e-United States kwakuse-Dutch Antilles nase-Aruba ngo-2009.
Usonkontileka wendawo endaweni yaseLaguna Beach uqale wabikela iziphathimandla ngesihluthu esibomvu, okwenza izikhulu zendawo, izifundazwe kanye nezifundazwe ukuthi ziqinisekise ukuthi sikhona, zenza ucwaningo lwendlu ngendlu futhi zabeka izicupho ezingu-250 ukuze kutholwe ukuthi “igciwane” likhona ngempela. . Abanye bayakhuthazwa ukuthi babike ukuhlasela kwabasolwa ngokushayela iCDFA Pest Hotline ku-1-800-491-1899.
Nakuba iningi lezihlahla zesundu lingezona ezomdabu eCalifornia, imboni yezihlahla zesundu ingenisa imali elinganiselwa ku-$70 million ngonyaka futhi abalimi besundu, ikakhulukazi abatholakala eCoachella Valley, bavuna imali eyizigidi ezingu-30 zamaRandi unyaka ngamunye.
Nakhu ukuthi isilokazane singalimaza kanjani, sichazwe yi-CDFA:
Izimpungushe zesifazane ezibomvu zesundu zabhoboza esihlahleni sesundu ukuze zenze umgodi ezizalela kuwo amaqanda. Insikazi ngayinye ingase izalela amaqanda angama-250, okuthatha cishe izinsuku ezintathu ukuchanyuselwa. Izibungu ziyavela kanye nomhubhe obheke ngaphakathi kwesihlahla, okuvimbela ikhono lesihlahla lokuthutha amanzi nezakhamzimba phezulu kuya phezulu. Ngemva kwezinyanga ezimbili zokuncela, izibungu zihluma phakathi kwesihlahla isikhathi esingamaviki amathathu ngaphambi kokuba kuvele abadala ababomvu ngokunsundu. Abantu abadala baphila izinyanga ezimbili kuya kwezintathu, phakathi naleso sikhathi badla amasundu, bakhwelana kaningi futhi bazalele amaqanda.
Izimpungushe esezikhulile zibhekwa njengamandiza aqinile, zihamba ibanga elingaphezu kwesigamu semayela zifuna izihlahla. Ngokuhamba kwezindiza okuphindaphindiwe phakathi kwezinsuku ezintathu kuya kweziyisihlanu, ama-weevil kubikwa ukuthi angakwazi ukuhamba cishe amakhilomitha amane nesigamu ukusuka lapho achanyuselwa khona. Zikhangwa izintende zesundu ezifayo noma ezilimele, kodwa futhi zingahlasela izihlahla ezingalimele. Izimpawu ze-weevil kanye nezimbobo zokungena izibungu ngokuvamile kunzima ukuzibona ngoba izindawo zokungena zingambozwa ngamahlumela kanye nemicu yezihlahla. Ukuhlola ngokucophelela amasundu ahlaselwe kungase kubonise izimbobo emqheleni noma esiqwini, ngokunokwenzeka kanye noketshezi olunsundu olumpophoma kanye nemicu ehlafunwayo. Ezihlahleni ezigcwele kakhulu, ama-pupal awile kanye nezintwala ezindala ezifile zingatholakala eduze kwesisekelo sesihlahla.
