Iminyovu yase-Asia iyinhlobo ehlaselayo futhi ithinta izinyosi zethu

Izinhlobo ezihlaselayo zidala izinhlekelele ezinkulu emvelweni nasezinhlotsheni zomdabu. Izinhlobo ezihlaselayo zingakwazi ukwenza insimu yenze indawo ngamathwala ahlukahlukene ezokuthutha. Kungaba ngabantu, noma ngolwandle, njll.

Umnyovu wase-Asia (UVespa vetulina) sekuyinhlobo ehlaselayo ezweni lethu. Kubucayi kangangoba kusongela abantu bomdabu bezinyosi zethu zezinyosi. Kuzokwenzekani ngaleminyovu?

Izinhlobo ezihlaselayo

Ukuze siqonde ukuthi kungani uhlobo oluvela kwenye indawo luhlasela futhi lube yingozi kangaka, kufanele sazi izinhloso zalo. Yebo, uhlobo olulodwa lwaziwa njengolungenangqondo lapho luzala futhi ikholoni indawo okungeyona eyayo.

Izizathu zokuthi kungani uhlobo oluthile lwezilwane lungahlala endaweni ethile futhi lususe noma lubhubhise izinhlobo zemvelo yilezi ezilandelayo:

• Bayakwazi ukuzivumelanisa kangcono kwisimo sezulu sendawo entsha.
• Bantula isilwane esidla imvelo ngakho-ke baqala ukukhula kakhulu.
• Bayakwazi ukusinda, bathole ukudla nendawo yokuhlala ukuze bakwazi ukuzala futhi bandise amakoloni abo.
• Imvamisa, izinto eziphilayo ezisebenza ngokuzimela azilungele ukuzivikela ezinhlotsheni ezintsha ezikhona ku-ecosystem yazo, ngoba azikwazanga ukuzivumelanisa nokwakha izindlela zokuzivikela kuzo.

Yingakho izinhlobo ezihlaselayo ziba isizathu esibucayi sokunyamalala nokuhamba kwezinhlobo zomdabu emhlabeni wonke.

Iminyovu yase-Asia njengenhlobo ehlaselayo

Okunye kokukhathazeka okudalwe ukuhlasela kwale minyovu yase-Asia ukwazi ukuthi kungenzeka yini ukuthi lolu hlobo kungaholela ekunyamalaleni kwezinyosi zethu zezinyosi. Izinyosi zomdabu ezithinteka kakhulu yile minyovu engenayo yilezo zeCatalonia. Abamele umkhakha wokufuya izinyosi baqinisekisa ukuthi uma ukuhlasela kweminyovu yase-Asia kuqhubeka kanjena, kuzodala ukunyamalala kwezinyosi eminyakeni emithathu noma emine, ngisho nokubeka ukuphepha kwabantu engcupheni.

UJoan Pino uchwepheshe ekuhlaselweni kwezinto eziphilayo futhi uyisekela lomqondisi weCentre for Ecological Research and Forest Applications (Creaf). Uchaze ukuthi umnyovu wase-Asia usakazeka ngokushesha kwezinye izindawo zaseCatalonia, njengoba kwenzeke nakwezinye izifunda zeSpain yonke. Kodwa-ke, uchwepheshe ubheka ukuthi akukho datha, idatha noma izifundo ezenzelwe isayensi eziphakamisa ukunyamalala kwezinyosi eCatalonia ngenxa yeminyovu yase-Asia.

Ukutadisha iVespa velutina

Abaphenyi beCreaf bebelokhu befunda uphondo lwase-Asia iminyaka. Bakwazile ukuthuthukisa amamodeli okubikezela ekwandisweni kwalesi sinambuzane. Imodeli isuselwa ku- ukuguquguquka kwesimo semvelo njengokushisa, umswakama, uhlobo lohlaza, njll. Ukuguquka kwesimo sezulu kuvuna lolu hlobo lomnyovu, okunikeza iCatalonia indawo ekahle yokukhiqiza iminyovu.

Imodeli yokubikezela eyakhiwa ngo-2014 idwebe ibalazwe lokuba khona kwalomnyovu futhi ihambisana neqiniso elibonwayo njengamanje lokwanda kwesifunda. Ngokwesibikezelo salolu hlobo, ezinye izifunda zingathinteka ngomonakalo omkhulu emkhakheni wokufuya izinyosi.

Umonakalo odalwe uphondo lwase-Asia ekufuyweni kwezinyosi uyahlukahluka kakhulu, kuya ngezindawo ezithile zomhlaba, kepha azikho izifunda ezithintekile ezikhulumile kuze kube manje ukunyamalala kokufuywa kwezinyosi, nokuncipha kokunyamalala okuphelele kwezinyosi.

 “Kuhlale kunethuba lokuthi umuntu adlule asondele kakhulu noma ashaye isidleke somnyovu athole izitinyela eziningana, kodwa ingozi ifana kakhulu naleyo yeminyovu sonke esiyaziyo. Ngokunjalo, siyazi futhi ukuthi iminyovu - yezinhlobo eziningi - idla izinhlobo eziningi zokudla ngakho-ke akufanele kusimangaze ukuthi sibona iminyovu yase-Asia ezinsaleleni zezilwane ezifile noma ukudla okushiywe endaweni yepikiniki; Kodwa angicabangi ukuthi kungenzeka ukuthi iminyovu yase-Asia ibulale futhi idle izingulube zasendle ezinsukwini ezine, ”kusho uJoan Pino.
