Isithombe esinesinqumo esiphezulu esibonisa umonakalo we-flea beetle emaqabunga e-arugula, enezimbobo ezincane zokudla kanye namaqabunga aluhlaza acwebezelayo
Flea Beetle Damage on Arugula Leaves
Lesi sithombe sendawo esinekhwalithi ephezulu sithwebula umbono oseduze wamaqabunga e-arugula (Eruca sativa) abonisa umonakalo ophawulekayo obangelwa yizimbungulu. Isithombe sibonisa iqoqo eliminyene lamaqabunga e-arugula, amaqabunga ehlangana futhi ehlangana ngendlela yemvelo, ephithizelayo kancane. Iqabunga ngalinye libonisa izimbobo eziningi ezincane, ezingafani—izimpawu zomsebenzi wokudla izimbungulu. Lezi zimbobo ziyahlukahluka ngobukhulu nangokusabalala, ezinye zibonakala njengezimbobo ezincane kanti ezinye zinkulu kancane futhi zinde kakhulu, zivame ukugxila eduze kwemithambo ephakathi noma emaphethelweni amaqabunga.
Amaqabunga e-arugula aluhlaza okotshani, kusukela koluhlaza okotshani olujulile kuya kokukhanya okukhanyayo kwe-lime, anezinhlobonhlobo ezingabonakali zombala ezibonisa ukuhlukahluka kwemvelo kwesitshalo. Imiphetho yawo enama-lobe, enama-wave kanye nokuma okude kubonakala ngokucacile, kanti ubuso bamaqabunga bubonisa ukuthungwa okuncane okungacwebezeli. Iziqu eziluhlaza okotshani ziyasonta kulo lonke ukwakheka, zengeza umehluko wesakhiwo futhi ziqondise iso lombukeli kulo lonke uhlaka.
Ukukhanya kwelanga kwemvelo kukhanyisa lesi sithombe kusukela phezulu kwesobunxele, kuveze izithunzi ezithambile ezithuthukisa ukujula nokuthungwa kwamaqabunga. Ukukhanya kugqamisa imigqa yamaqabunga kanye nemiphetho yemigodi, eminye yayo ekhombisa ukuba nsundu okuncane noma i-necrosis, okubonisa umonakalo omdala. Ingaphambili ligxile kakhulu, lembula imininingwane emincane njengemithambo yamaqabunga kanye nokuthungwa kobuso, kuyilapho ingemuva lithamba kancane kancane libe ukufiphala okuncane, okudala ukujula okungajulile kwensimu okugcizelela amaqabunga alimele.
Ukwakheka okuphelele kufakwe uhlaka oluqinile, kungekho nhlabathi ebonakalayo noma indawo ezungezile, okuvumela umbukeli ukuthi agxile ngokuphelele ebangeni kanye nephethini yomonakalo we-flea beetle. Lesi sithombe silungele izinjongo zemfundo, zokuxilonga, noma zokubhala uhlu, sinikeza ukumelwa okungokoqobo nokunembile kobuchwepheshe komthelela wezinambuzane eziluhlaza okotshani. Iphalethi yombala ibuswa yimibala eluhlaza, ephawulwe yizikhala ezimnyama zemigodi yokudla kanye nomphetho onsundu ngezikhathi ezithile, okudala umehluko obonakalayo phakathi kwamandla nomonakalo.
