Izihlahla, ikakhulukazi lezo ezithela izithelo ezidliwayo, zisengozini enkulu yokuhlaselwa yizilokazane namagciwane abangela izifo. Uma sigxila kulawo weQuercus, futhi ikakhulukazi ama-oki nama-holm oak, i I-Tortrix viridana Kuyisinambuzane ukuthi kubalulekile ukuthi sazi ngomonakalo ongawenza.
Yisinambuzane esinamaphiko sombala oluhlaza okotshani, kepha esigabeni sesibungu sinesifiso sokudla. Ngakho-ke ake sibone ukuthi yiziphi izinyathelo okufanele sizithathe ukuze zingasidaleli izinkinga.
Kuyini lokhu?

La I-Tortrix viridana, aziwa ngamagama ajwayelekile uPiral del Roble noPiral de la Encina, ungowokuzalwa epidopteran emahlathini abanzi eYurophu, eNyakatho Afrika nase-Asia Minor. Mncane kakhulu ngosayizi, u-18 kuye ku-23mm, unamaphiko amnyama angemuva anezindawo ezimhlophe kuthi ezedlule ziluhlaza okotshani.
Umjikelezo wayo wezinto eziphilayo ulandelayo:
- Ukubeka: insikazi cishe amaqanda angama-60, embozwe isibopho. Okuthunyelwe ngakunye kungu-1,25 kuye ku-1,35mm ubude no-0,90 kuye ku-0,95mm ububanzi.
- Isibungu:
- Isigaba sokuqala: mpunga okhanyayo nekhanda elimnyama. Ilinganisa cishe i-1,8mm.
- Isigaba sesibili: sine-hazel ngombala, sithande ukuba mpunga. Ilinganisa cishe ngo-4mm.
- Isigaba sesithathu: sifana ngombala nesigaba esedlule, kepha sikhulu, 7mm.
- Isigaba sesine: siyefana nesigaba esedlule, kepha silinganisa u-10mm.
- Isigaba sesihlanu: yi-leaden ngombala, enemilenze emnyama ephaphathekile. Linganisa kusuka ku-15 kuye ku-19mm.
- I-Chrysalis: inombala onsundu onsundu, ivulekile futhi ilinganisa u-9-11mm ubude ngo-2-2,5mm ububanzi.
- Umuntu omdala: iba yisinambuzane esinamaphiko, ngombala oluhlaza okotshani. Abesilisa nabesifazane abahlukaniswa ekuqaleni.
Ziyini izimpawu nomonakalo odalekayo?
Uma sithinte izitshalo sizobona lezi zimpawu / umonakalo olandelayo:
- Ukuluma kweLeaf
- Ukuwa kwangaphambi kwesikhathi (defoliation)
- Ukwehla kokukhula
- Ukubukeka okujwayelekile »okudabukisayo»
Ilashwa kanjani?
Izindlela zemvelo

Kungaphathwa ngayo izimuncagazi, njenge- I-Pimpla maculator, noma Isikhuthazi sePhaeogenes, ezithola ukukhubaza cishe amaphesenti ayisishiyagalombili wesifo. Enye inketho ethakazelisa kakhulu ukubhekana nayo Bacillus thuringiensis.
Izindlela zamakhemikhali
Sisebenza nge amadlozi, ngokususa uthuli.
Manje uzokwazi ukuthi wenzeni lapho ubona ifayela le- I-Tortrix viridana ukundiza ngeQuercus 🙂 yakho.
