Iyini i-weevil nokuthi ungalwa kanjani nayo

Ziyanda izinambuzane ezingavamile izitshalo zethu okufanele zilwe nazo uma zifuna ukuqhubeka. Enye yazo yi- i-black weevil, uhlobo lwebhungane olungadala umonakalo omkhulu ezinhlobonhlobo zezitshalo, kuhlanganise nama-agave. Eqinisweni, inomkhuba kubo kangangokuthi yaziwa kakhulu ngegama le-agave weevil.

Iyisihlobo esiseduze se-weevil ebomvu yesundu, nakuba ingathinteki. Manje, njengaye, iyisilokazane okufanele sibonwe ngokushesha ngangokunokwenzeka ukuze usindise isitshalo, njengoba kungenjalo kuyoba nzima kakhulu ukufeza.

Umsuka kanye nezici ze-wewevil

I-black weevil, igama layo lesayensi I-Scyphophorus acupunctatusKuwubhubhane oluvela eMelika. Ibhungane, esigabeni salo esidala, licishe libe ngamasentimitha amathathu ubude futhi linoqhwaku olude., okuyikhona elizisebenzisayo ukuze liziphakele. Kodwa-ke, esigabeni sayo sokuvuthwa ayibiki inkinga enkulu, ngaphandle uma ishiya amaqanda ayo ezitshalweni.

Futhi yilokho izibungu zinesifiso esikhulu sokudla. Lezi zibhubhisa izicubu ezithambile ngokushesha, kangangokuthi zingakwazi ukuqeda impilo yezitshalo zethu ezinsukwini ezingaba ngu-20-30, ngisho nangaphansi uma kusehlobo, njengoba kulapho zisebenza kakhulu. Ziphakathi kwamasentimitha angu-1,8 no-2 ubude, futhi zi-beige ezinekhanda elinsundu.

Wenza muphi umonakalo ezitshalweni?

Izimpawu nomonakalo owudalayo yilezi ezilandelayo:

• Izimbobo emaceleni
• Ukubhujiswa kwezicubu ezithambile ngaphakathi
• Ukubola, okubangelwa amagciwane Erwinia carotovora eyethulwa wumgqumeni uqobo
• Ukubukeka kwesikhunta esingosomathuba, njenge U-Aspergillus niger, okusheshisa ukubola kwezitshalo
• Ezimweni ezimbi kakhulu, ukufa kwezitshalo

Futhi, isitshalo esithintekile singase sibe nephunga elibi. Lokhu kungenxa kokubili isikhunta namagciwane, okuyinto ndawonye ngokushesha buthaka it.

Izithinta ziphi izitshalo?

I-weevil ithinta izinhlobonhlobo zezitshalo. Kubo bonke, eyinhloko yi-agave, kodwa kukhona ezinye: 

• Izinyoni zepharadesiI-Strelitzia reginae, I-Strelitzia augusta, Njll)
• I-Aloe ne-Aloidendron
• I-Pachypodium lamerei nabanye
• Izihlahla zikabhanana (Musa)

Kodwa Ngeke kukhishwe ukuthi kuthinta nama-cicas nezihlobo zabo eziseduze (Dioon, Zamia, Encephalortos, njll.).

Ngingayivimba kanjani i-weevil ukuthi ithinte izitshalo zami?

Nakuba kungenakwenzeka ukuqeda ingozi yazo, kukhona uchungechunge lwezinyathelo ezingase (futhi ngokombono wami, kufanele zithathwe) ukuze kugcinwe izitshalo zethu zivikelwe. Zimi kanje:

Thenga izitshalo ezinempilo

Lezi yizisekelo. Izitshalo zethulwa zivela emazweni ahlukahlukene, lapho zinezinambuzane nezifo zazo. Abaphathi kufanele baqinisekise ukuthi bonke banempilo, into abayitholayo ngenxa yesitifiketi se-phytosanitary, okuyimpoqo ukuba sibe nayo.

Lapho siyothenga eyodwa, kufanele siqiniseke ukuthi ilungile; okungukuthi, ayinalo uhlobo lwenkinga. Uma inezimbobo, amaqabunga amnyama noma akhuntile, futhi / noma inuka kabi, akufanele ithengwe ngoba uma kungenjalo singafaka engozini izitshalo esinazo ekhaya.

Susa izitshalo ezithinteka kakhulu yi-weevil

Ngokushesha lapho izimpawu zibonakala, kungcono ukusiphula izitshalo futhi uzishise, ikakhulukazi uma zithinteka kakhulu (uma ngokuphambene nalokho ziseluhlaza futhi zibukeka ziqinile, zingelashwa). Lokhu kulawula isibalo sezintuthwane endaweni, futhi zivimbele ukuba zande.

Yenza imithi yokuvimbela njalo ngonyaka

Njengoba kwenziwa nge- Isikhumba esibomvuNgomnyama, ukwelashwa okuningana ngonyaka kufanele kwenziwe ukuze izitshalo zihlale ziphilile. Ziningi izindlela ezikhona yilezi:

• Amakhemikhali okubulala izinambuzane: I-Chlorpyrifos + Imidacloprid, inqobo nje uma ivunyelwe ezweni lethu. Kufanele isetshenziswe inyanga eyodwa, futhi ngenyanga elandelayo enye. Akufanele zixutshwe, ngoba ngokwenza njalo isitshalo singafa.
• Izicupho zePheromone: njengalezo zikairomonas. Lezi zingafakwa ezingadini ezinkulu, kodwa azinconywa ezincanyana ngoba zikhanga kakhulu izimpungushe, futhi ikhambi lingagcina selibi kakhulu kunesifo.
• Ukulawulwa kwezinto eziphilayo: ezindaweni ezisuka kuzo kuyabonakala ukuthi i-black weevil inezitha zemvelo, njengezintuthwane ezizingelayo (i-Ectamomma ne-Odontomachus) kanye nama-braconids. Bakhona naseSpain, kodwa iqiniso wukuthi ukusebenza kwabo kuncike kakhulu ekutheni izimpawu zitholwa nini. Futhi ukuthi uma kwenzeka ngokushesha, amathuba amaningi okusinda kuzoba nawo.

Ingquza njengokudla

Njengeqiniso elimangalisayo, sifuna ukukutshela lokho ezindaweni eziphuma kuzo izibungu zomgqumeni zithengiswa ukuze zidliwe ngabantu, kungaba yosiwe noma yosiwe. Kuthiwa banambitheka kamnandi, nakuba mina ngokwami ​​angicabangi ukuthi ngingalokotha ngizame, kunjani ngawe?

Sengikushilo lokho, ngiyethemba ukuthi lokhu enginitshele khona ngalesi sifo kunisizile.
