Ama-aphid yizitha eziphilayo zezo zonke izihlahla zezithelo hhayi nje kuphela. Kungaba luhlaza, obomvana, ophuzi, obomvu nabomnyama. Kuyinto inambuzane efinyelela ubude 4 mm. Ngenxa yesakhiwo somlomo wayo, ama-aphid akwazi ukuncelisa amagxolo kanye namaqabunga emithi yezithelo futhi adle ijusi layo. Ngenxa yalokho, umuthi ulahlekelwa amandla awo, unciphisa ukukhula kanye ne-fruiting.
Uma ama-aphid evele ensimini yabo emithini yezithelo, ke lesi sihloko sithinta kakhulu. Sizokutshela izimbangela ze-aphid, kanye nezindlela zokulwa nazo.
Ama-apidi emithini yezithelo
Ama-aphid ayizinambuzane ezikhetha izihlahla ezincane, amahlamvu awo namahlumela. Uma i-aphid ihlasele umuthi wakho eminyakeni yokuqala yokuphila kwayo, yayizoholela ekuthuthukiseni isitshalo, ukunciphisa ukukhula, amaqabunga kanye namaqabunga awela, izithelo ezivuthiwe ekuvuthweni. Emithini yezithelo ezonakaliswe yilesi sifo, izithelo zikhula ezincane ngokwanele, futhi, zingabi nokuvuthwa, ziwa. Izitshalo ezinjalo ziyancipha kakhulu kwiqhwa, isivuno esincane, kanye nokwanda okuncane.
Ngaphezu kokuncelisa wonke ama-juice esihlahleni, i-aphid iyayibethela ngeminyango eqinile. Ukunikezwa kuyindawo enhle yokuzalanisa ama-yeasts, i-fungus, nama-virus ahlukene. Izintuthwane ziyakuthanda kakhulu into ekhishwa yi-aphid, ngakho iyakwazi ukuyivikela ezinambuzaneni ezisongela ukuphepha kwayo (ladybugs, syrphids, lacewings, njll). Izintuthwane nazo zisiza ukuthatha ezinye zezitshalo ensimini.
Ngaphandle kokulimala esitshalweni, ama-aphid angakwazi ukubekezelela izifo ezinama-viral, fungal nezinye izifo eziyingozi kubantu nasezilwaneni.
Uphi i-aphid evela emithini?
Ngakho-ke, kunezizathu eziningana zokuvela kwama-aphid engadini yakho. Yiqiniso, isizathu esiyinhloko sokwenzeka kwayo ukutheleleka emasimini angomakhelwane. Kodwa-ke, ngeke kubonakale kuwe uma izitshalo zakho zivikelwe yizintombikazi, ama-lacewings, kanye nezinye izinambuzane, lapho ama-aphid esaba khona.
Akunakwenzeka yini ukuthi ungakwazi ukutshala isitshalo, ngoba lokhu kuholela ekunciphiseni amapheshana, futhi lokhu kuzuzisa kuphela ama-aphid.
Indlela yokubhubhisa ama-aphid ezihlahleni?
Ukucubungula umuthi kusuka kuma-aphid kuyadingeka ngisho nangaphambi kokuthi amaqabunga aqedwe. Izindlela zokupheka eziningana ezivivinya isikhathi sokuzivikela nendlela yokukhipha ama-aphid ezihlahleni:
- ukulawula ama-aphid kuzosiza izaqathe, i-dill, i-fennel, kanye ne-parsley - ziyakuthanda ukuqhuma, kanti nazo ziyizitha ezimbi kunazo zonke zezinhluzane ze-aphid;
- Ukwesabisa ama-aphid amnyama kuzosiza i- lavender ne-thyme, etshalwe ezungeze izihlahla zezithelo;
- Isixazululo esilandelayo sizosiza ekubhubhiseni ama-aphid emithini: thatha i-300 g yesepha bese uyihlanza ngamalitha angu-10 amanzi, kuyinto efiselekayo ukuthi amanzi athambile (umfula noma amanzi emvula kufanelekile). Ukufafaza izitshalo ngalelixazululo kuyadingeka lapho ama-aphid evakashela nje ingadi yakho.
- Ukuze uzenzele i-aphid emnyama ingaba ne-nasturtium, ezosindisa umuthi wakho ekuhlaselweni kwezinambuzane;
- ukuhlunga izihlahla zezithelo ngokumelene nama-aphid mhlawumbe indlela esheshayo futhi ephumelelayo kakhulu yokulawula izinambuzane.
Nokho, khumbula ukuthi ukuphatha izihlahla zezithelo ngokumelene nama-aphid ngamakhemikhali akuyona indlela engcono yokulwa nayo. Yiqiniso, bazokwazi ukubhekana nayo ngokuphumelelayo, kodwa emva kwesikhathi izinambuzane zizovela futhi, kodwa izinambuzane ezizuzisa ingadi yakho ngeke ziphinde zibe ngenxa yezinhlayiya.
Ukuvikelwa kwezihlahla ngokumelene nama-aphid
Ukwelashwa kwezihlahla ezivela kuma-aphid, Yebo, kuzosiza ukuqeda izinambuzane okwesikhashana, kodwa kungcono ukunakekelwa kusengaphambili ukuthi le bhungane elibi ayifuni engadini yakho.
Ukuze wenze lokhu, udinga ukuqeda ukhula njalo ensimini yakho, ngoba yindawo yokuzalanisa ama-aphid. Ukuze isitshalo sikhule ngokushesha futhi ama-aphid akonakalisiwe, kufanele atshalwe ngokushesha ngangokunokwenzeka. Kufihlekile ukuhluma, umuthi udinga ukufafazwa ngamafutha ommbiwa. Ekwindla, emva kokukhululwa kwezithelo, isitshalo kumele siqede amagxolo endala bese sihamba phakathi kweqhwa.
