Ubomvu obomvu obomvu (Rhynchophorus ferrugineus)

Noma ngabe unesihlahla sesundu engadini yakho noma uma ungumqoqi walezi zitshalo futhi uhlala endaweni enesimo sezulu esifudumele noma esipholile e-Old Continent, kubalulekile ukuthi wazi konke ngakho. Isikhumba esibomvu, esinye sezinambuzane eziyingozi kakhulu esinazo namuhla.

Esigabeni sayo sokukhula ayiyona ingozi, kepha kulapho ichamusela iqanda bese iqala ukondla ingaphakathi lomuthi wesundu. Eqinisweni, ngaphandle kokuthi welashwe kulesi sikhathi sokuqala, cishe ngeke asinde. Ungakugwema kanjani?

Umsuka nezici

I-protagonist yethu i-weevil (uhlobo lwe-beetle, kepha enomzimba omude futhi omncane) ongowokuzalwa e-Asia eshisayo, ogama lakhe lesayensi I-Rhynchophorus ferrugineus. Inobukhulu obungamasentimitha amabili kuya kwamahlanu futhi ibomvu, into eyenza kungacaci.

Umjikelezo wayo wempilo uhlala ezinsukwini eziyi-130 kuya kwezingama-200, futhi umi kanje:

• I-Oviposition: ngemuva kokukhwelana, insikazi izalela amaqanda aphakathi kwama-300 nama-500 emithini yesundu ehlukahlukene, isebenzisa amanxeba kanye / noma imifantu engaba nayo lezi zitshalo. Ukubekwa kwenziwa ngeziqu zokugcina kanye nakwizicubu ezithambile zezisekelo zamaqabunga.
• Izibungu: Ngokushesha nje lapho zizalwa, ziphuzi ngokumhlophe futhi azinayo imilenze. Ekhanda labo banemihlathi evundlile evundlile, abangafaka ngayo imipheme kusuka kuma-axils amaqabunga kuye esihlokweni, ngaphakathi lapho bazokondla khona kakhulu.
  Lesi sigaba sihlala cishe izinsuku ezingama-95-96. Lapho ifika, ukukhula kwayo kwesibungu kuqediwe, bakha i-cocoon 4 kuya ku-6 cm ubude ngemicu ekhishwe esihlahleni sesundu.
• Pupa: umbala onsundu ngokubomvu ngombala obomvu, futhi ukwakheka ngaphakathi kukakhukhunathi. Ngalesi sigaba lesi sinambuzane sibhekana nesimo sokuguquguquka, esingahlala phakathi kwezinsuku eziyi-15 nezingama-30.
• Umuntu omdala: lapho ifinyelela kulesi sigaba, uma kusekhona okokutshala engondla ngakho, kuzohlala izinsuku ezimbalwa ngaphezulu emthini wesundu, uma kungenjalo, izokuya kwesinye, ikhangwe iphunga lezinye izihlahla zesundu ezilimele cinga umlingani ozoshada naye bese uqala umjikelezo.

Ungahlukanisa kanjani owevu obomvu wesilisa kowesifazane?

Ziyafana kakhulu, kepha eyeduna incane ngosayizi futhi inesiqeshana sezinwele emlonyeni wayo.

Kuthulwe kuphi?

Umhlanga obomvu selisakazekele e-Afrika, eYurophu naseMelika. Endabeni yeSpain, yavela okokuqala e-Almuñécar ngo-1993. Ukusuka lapho, yasakazekela ezingxenyeni ezahlukahlukene zempumalanga ye-Andalusia, iMurcia kanye noMphakathi waseValencian ngokusebenzisa izihlahla zesundu ezazingeniswe eGibhithe.

Ngo-2005, wafika esihlahleni sesundu i-Elche, esikhulu kunazo zonke eYurophu. Futhi eziqhingini zaseCanary wasongela kakhulu izinhlobo zakhe zomdabu: IPhoenix canariensis. Eminyakeni eyisithupha kamuva, ngo-2011, yafika eJerez de la Frontera, lapho yathinta khona izinhlobo ezingaphezu kuka-200. Ngo-2014 wafika eBadajoz, esifundeni saseCatalan eRibera de Ebro, naseMalaga Park, lapho abulala khona izihlahla zesundu eziyikhulu nekhulu.

Kuze kube manje (2019) selisabalale cishe kuyo yonke iNhlonhlo Yase-Iberia (ngaphandle kwezindawo ezinamakhaza kakhulu), kanye naseziqhingini zaseCanary naseBalearic, yize ukusabalala kwayo kuyalawulwa.

Ziyini izimpawu nomonakalo odalekayo?

Izimpawu nomonakalo odalwe ukuhlaselwa kwe-weevil ebomvu ekuqaleni akubonakali kakhulu; Ngaphezu kwalokho, into ejwayelekile ukuthi bacabanga ukuthi bavele badlula esikhathini esibi (ngokwesibonelo, ukubanda noma ukoma), noma ukuthi bayimiqemane. Kepha Kufanele unake kakhulu, uyigcine nsuku zonke, ngoba lapho izimpawu zisobala kakhulu, impilo yesitshalo ilenga ngentambo:

• Iso lesundu liba buthakathaka.
• Iqabunga eliphakathi nendawo, lelo elisebenza njengomhlahlandlela, libalekile.
• Ubukhona bezimbobo ezincane - imipheme- lapho kufakwa khona amaqabunga.

• Izimbali nokuthela ngesikhathi esingalungile (kwesinye isikhathi, lapho isitshalo sibi kakhulu, sisebenzisa amandla aso okugcina ekudaleni inzalo).

Yimiphi imithi yesundu lapho umuthi wesundu obomvu uhlasela khona?

Kubo bonke ngokujwayelekile, kepha inesandulela salabo bohlobo Phoenix futhi ikakhulukazi i IPhoenix canariensis. Kepha uma ingekho, izokwenzela i- IWashingtonia, Brahea ... Umngani ubulawe yi-Pritchardia enkulu evela kulesi sinambuzane, ngakho-ke ungavumeli ukuqapha kwakho.
