Isithombe esinesinqumo esiphezulu somonakalo we-anyanisi thrips onemigqa yesiliva emaqabunga aluhlaza, okulungele ukuxilonga imifino kanye nokusetshenziswa kwezemfundo.
Thrips Damage on Onion Leaves
Lesi sithombe esinesinqumo esiphezulu, esibheke endaweni sibonisa ukufinyezwa okuningiliziwe komonakalo we-onion thrips (Thrips tabaci) emaqabungeni ka-onion aluhlaza (Allium cepa). Ukwakheka kwalesi sitshalo kunamaqabunga amathathu ahambisanayo ahlelwe ngokuvundlile ohlakeni, kanti iqabunga eliphezulu lisuka phezulu liye ekhoneni elingezansi kwesokudla, iqabunga eliphakathi libonakala kancane ngaphansi kwalo, kanye neqabunga elingezansi lihamba lihambisana neliphezulu.
Ukugxila okuyinhloko okubonakalayo kusemigqeni emhlophe njengesiliva ehamba ngobude phezu kwamaqabunga. Le migqa iyisibonakaliso somonakalo wokudla kwama-thrips, obangelwa izingxenye zomlomo zalesi sinambuzane ezimunca ama-rasping ezidabula amangqamuzana e-epidermal bese zikhipha okuqukethwe kwawo. Umonakalo obangelwayo uveza izicubu zamaqabunga ezingaphansi, ukhiqize ukukhanya okukhanyayo, okusansimbi okungafani kahle nezindawo eziluhlaza ezinempilo.
Amaqabunga abonisa imibala ehlukahlukene eluhlaza, kusukela ku-emerald ejulile eduze kwemingcele kuya kuluhlaza okotshani olukhanyayo, olukhanyayo kakhulu phakathi nendawo. Imigqa efana nesiliva iyahlukahluka ngobubanzi nangokuqhubeka—eminye imincane futhi iqondile, kanti eminye ibanzi futhi iqhekekile. Ngaphakathi kwezindawo ezonakele, ubuso bamaqabunga bubonakala buqinile futhi buyi-granular, bunezinhlayiya ezincane eziphakanyisiwe kanye namabala aphuzi ngezikhathi ezithile, okungenzeka kube yi-frass noma i-fungal colonization yesibili.
Amaphethelo amaqabunga abushelelezi futhi agobile kancane, aneziphambeko ezincane njengezindawo ezincane ezinsundu kanye nama-undelions amancane. Ukukhanya kuthambile futhi kuyasabalala, kuveza izithunzi ezithambile ezithuthukisa ukuthungwa nokujula kobuso bamaqabunga. Ingemuva lifiphele ngamabomu, lakhiwe ngemibala ensundu yomhlabathi kanye neluhlaza okotshani okuthulisiwe, okuhlukanisa umuntu futhi kugcizelele izici zokuxilonga.
Lesi sithombe silungele ukuhlonza amasiko ezitshalo, izinto zemfundo, iziqondiso zokuphathwa kwezinambuzane, kanye namakhathalogi abonakalayo. Sinikeza ubufakazi obucacile obubonakalayo bomonakalo we-thrips, okusiza ekuboneni nasekuqondeni umthelela wezinambuzane ezitshalweni zika-anyanisi. Ukwakheka kulinganisela ukucaca kobuchwepheshe kanye nokuba ngokoqobo kobuhle, okwenza kufaneleke kokubili ezimweni zesayensi kanye nezokufinyelela umphakathi.
