Yintoni i-weevil kunye nendlela yokulwa nayo

Ziyanda izitshabalalisi ezingaqhelekanga ekufuneka izityalo zethu zilwe nazo ukuba zifuna ukuqhubeka. Omnye wabo ngu I-black weevil, uhlobo lwebhungane olunokubangela umonakalo omkhulu kwiindidi ezininzi zezityalo, kuquka iiagave. Ngapha koko, inombono onjalo kubo kangangokuba yaziwa kakuhle ngegama le-agave weevil.

Isihlobo esisondeleyo se-weevil ebomvu yesundu, nangona ingachaphazeleki. Ngoku, njengaye, sisitshabalalisi ekufuneka sibonwe ngokukhawuleza ukuze usindise isityalo, ekubeni kungenjalo kuya kuba nzima kakhulu ukufezekisa.

Imvelaphi kunye neempawu ze-weevil

I-wevil emnyama, egama layo lezenzululwazi IScyphophorus acupunctatusSisibetho esivela eMelika. Nguqongqothwane othi, xa umdala, umalunga neesentimitha ezi-3 ubude kwaye unomlomo omde., nto leyo eyisebenzisayo ukuzondla ngokwayo. Nangona kunjalo, kwisigaba sayo sokuvuthwa ayifaki ingxaki enkulu, ngaphandle kokuba ishiya amaqanda ayo kwizityalo.

Kwaye oko imibungu inomdla kakhulu. Ezi zitshabalalisa izihlunu ezithambileyo ngokukhawuleza, kangangokuba zinokuphelisa ubomi bezityalo zethu malunga neentsuku ezingama-20-30, nangaphantsi xa kusehlotyeni, kuba kulapho zisebenza kakhulu. Ziphakathi kwe-1,8 kunye ne-2 yeesentimitha ubude, kwaye zi-beige ezinentloko emdaka.

Wenza wuphi umonakalo kwizityalo?

Iimpawu kunye nomonakalo obangelwayo zezi zilandelayo:

• Imingxuma kwiincakuba
• Ukutshatyalaliswa kwezicubu ezithambileyo ngaphakathi
• Ukubola, okubangelwa yintsholongwane Erwinia carotovora evezwa ngumgquba ngokwawo
• Imbonakalo yomngundo engenelelayo, njenge UAspergillus niger, ezikhawulezisa ukubola kwezityalo
• Kwiimeko ezinzima, ukufa kwezityalo

Kwakhona, isityalo esichaphazelekayo sinokunuka kakubi. Oku kubangelwa zombini iifungus kunye neebhaktheriya, ezidibanisa ngokukhawuleza zenza buthathaka.

Zichaphazela eziphi izityalo?

I-weevil ichaphazela iintlobo ezininzi zezityalo. Kuzo zonke, eyona iphambili yiagave, kodwa kukho ezinye: 

• Iintaka zeparadesiIStrelitzia reginae, I-Strelitzia augusta, njl)
• Ikhala kunye neAloidendron
• IPachypodium lamerei nabanye
• Imithi yebhanana (Musa)

Kodwa Akunakukhutshwa ukuba ichaphazela i-cicas kunye nezihlobo zabo ezisondeleyo (Dioon, Zamia, Encephalortos, njl.).

Indlela yokuthintela i-weevil ekubeni ichaphazele izityalo zam?

Nangona kungenakwenzeka ukuphelisa umngcipheko wabo, kukho uluhlu lwamanyathelo anokuthi (kwaye ngokombono wam, kufuneka athathwe) ukugcina izityalo zethu zikhuselwe. Zimi ngolu hlobo lulandelayo:

Thenga izityalo ezisempilweni

Le zizinto ezisisiseko. Izityalo ziziswa kumazwe ahlukeneyo, apho zinezinambuzane kunye nezifo zazo. Abalawuli kufuneka baqinisekise ukuba bonke basempilweni, into abayifumanayo ngokubulela kwisatifikethi se-phytosanitary, ekunyanzelekileyo ukuba sibe nayo.

Xa sisiya kuthenga enye, kufuneka siqinisekise ukuba ilungile; oko kukuthi, ayinalo naluphi na uhlobo lwengxaki. Ukuba inemingxuma, amagqabi amnyama okanye anobumba, kunye / okanye ivumba elibi, akufanele lithengwe kuba kungenjalo sinokubeka esichengeni izityalo esinazo ekhaya.

Susa izityalo ezichatshazelwa kakhulu yi-weevil

Ngokukhawuleza ukuba iimpawu zifunyenwe, kungcono ukuncothula izityalo kwaye uzitshise, ngakumbi ukuba zichaphazeleke kakhulu (ukuba ngokuchaseneyo zihlala ziluhlaza kwaye zibukeka zinamandla, zinokuphathwa). Oku kulawula inani leengcongconi kule ndawo, kwaye kuthintele ukwanda.

Yenza unyango lothintelo minyaka le

Njengoko kwenziwa nge Ubomvu obomvuNgomnyama, unyango oluninzi ngonyaka kufuneka lwenziwe ukuze izityalo zihlale ziphilile. Kukho iindlela ezininzi ezinokuthi:

• Imichiza yokubulala izinambuzane: I-Chlorpyrifos + Imidacloprid, nje ukuba bavunyelwe kwilizwe lethu. Kufuneka isetyenziswe inyanga enye, kwaye kwinyanga elandelayo enye. AKUFUNEKA zidityaniswe, kuba ngokwenza njalo isityalo siya kufa.
• Pheromone imigibe: njengabo base kairomonas. Ezi zingafakwa kwiigadi ezinkulu, kodwa akukhuthazwa ukuba zincinci njengoko zinomtsalane kakhulu kwi-weevils, kwaye iyeza lingaphela libi kakhulu kunesifo.
• Ulawulo lwebhayoloji: kwiindawo zayo zemvelaphi kubonakala ukuba i-weevil emnyama ineentshaba zendalo, ezifana nezintuthwane zokuzingela (i-Ectamomma kunye ne-Odontomachus) kunye ne-braconids. Bakhona naseSpain, kodwa inyaniso kukuba ukusebenza kwabo kuxhomekeke kakhulu xa iimpawu zifunyenwe. Kwaye kukuba okukhona kwenzeka ngokukhawuleza, kokukhona amathuba okusinda aya kuba nawo.

Intungulu njengokutya

Njengenyaniso enomdla, sifuna ukukuxelela oko kwiindawo ezisuka kuzo imibungu yengca ithengiselwa ukutyiwa ngabantu, mhlawumbi yosiwe okanye yosiwe. Kuthiwa zinencasa emyoli, nangona mna ngokobuqu andiqondi ukuba ndingazama ukuzizama, kuthekani ngawe?

Ndithe, ndiyathemba ukuba le nto ndinixelele yona ngesibetho ikuncedile.
