Isibetho esimhlophe

Ngokuqinisekileyo uzibonele ngokwakho okanye weva impukane emhlophe ukuba unezityalo. Yenye yezona zinambuzane zixhaphakileyo kwilizwe lezolimo nasegadini. Ihlasela zombini izityalo zokuhombisa kunye nemifuno. Ke ngoko, iba sisisongelo rhoqo kubo bonke abo bafuna ukugcina izityalo zabo zikwimeko entle. Eminye yemihlaba echaphazelekayo yitamatato, i-zucchini, ipepile, i-melon kunye ne-watermelon.

Siza kuhlalutya nzulu esi sinambuzane sikucaphukisayo sikubonise indlela onokuthi uzichonge ngayo, uzithintele kwaye uzilahle xa kunokwenzeka ukuba izilimo zisulelekile. Ngaba uyafuna ukwazi yonke into malunga nesi sinambuzane?

Ifunyanwa njani ibhabhathane elimhlophe?

Esi sinambuzane saziwa ngegama lesayensi I-Trialeurode vaporariorum. Iyakwazi ukuchuma kwimozulu epholileyo kunye nefumileyo. Ke ngoko, ixesha lonyaka xa kukho uninzi lwezi zinambuzane lusentwasahlobo nasehlotyeni. Ziyi-miniscule ngobukhulu (phakathi kwe-1 kunye ne-3 millimeters) kwaye phakathi kweentsapho zazo sinokukwazi ukwahlula iintlobo ezahlukeneyo.

Sisibetho esiye savela ngendlela enzima. Unjalo ke ungeno lwayo lokuba nzima kakhulu ukulawula. Umjikelo wobomi bayo ujikeleze iintsuku ezili-10 ukuya kwezi-30. Ngeli xesha nje lexesha iyakwazi ukuziphinda-phinda, ukufikelela Amaqanda angama-80 ukuya kwangama-300 ngexesha. Oku kuyenza ibe yinto ekhula ngokukhawuleza kakhulu.

Amandla okuhlasela izityalo

I-whitefly inakho ukuhlasela izityalo ukutsala umlomo onayo. Itya incindi yamagqabi ade omile. Ubukho bayo bunokubonwa ngokujonga ngaphantsi kwegqabi. Zibekwe apho ngokuchanekileyo kuba yindawo enezona ndawo zininzi zemingxunya yesityalo kwaye zinokufikelela okungcono kuncindi. Banokufumaneka nakwisiqu.

Umonakalo onokubangela ukuba ubaluleke kakhulu. Ngokutyisa incindi, ishiya izityalo zibuthathaka kwaye zibangele ukumisa kuphuhliso lwayo kunye nelahleko yeziqhamo.

Ezinye zeempawu ezinokubonwa kwinkcubeko ye-whitefly echaphazelekayo kukubonakala kwamabala akhanyayo kunombala oluhlaza oqhelekileyo. Amagqabi owomileyo kunye natyheli nawo ayaqwalaselwa kwaye kuvela imolasses. Ukuba isityalo sinesi sifo, inokuba yimvelaphi yolunye usulelo kunye nezifo, ezinje nge-chlorosis okanye isibindi.

Ungayikhusela njani i-whitefly

Nanini na xa uthetha ngezifo kunye nezitshabalalisi, okona kulungileyo kukuthintela. Ukuthintela ukwanda kwe-whitefly kuso nasiphi na isityalo kusivumela ukuba singabinakho ukujongana neziphumo. Ukuba izinambuzane zivela kwizityalo eziluhlaza, ziyingozi kakhulu ngenxa yenqanaba eliphezulu losulelo.

Amanye amanyathelo anokunceda ukuyilawula ngala:

• Vumela amarhamncwa endalo (ladybugs) isenzo sokuhlasela i-whitefly.
• Ukuba sizinkcenkceshela izityalo ngokuqhubekayo nangokwaneleyo, siza kuzithintela zinganwenwi.
• Kubalulekile ukubambelela kwiishedyuli zokutyala esezisekiwe.
• Phuhlisa ukujikeleza kwesityalo unyaka wonke.
• Susa ukhula nokhula ukuvela malunga nezityalo.
• Lawula ukubonakala kweembovane. Iimbovane zikhusela i-whitefly kwiintshaba zayo zendalo.

Kwelinye icala, ukuba i-whitefly sele ivele kwizityalo zakho, kuya kufuneka ubhenele kwiimveliso ezizodwa. Kukho imichiza yokubulala izitshabalalisi eyahlukeneyo esebenza kwinkqubo yokutya esembindini kunye neebhloko ze-aceylcholine receptors. Ngale ndlela ukuhanjiswa kwentshukumisa yovalo kuyaphazamiseka kwaye inambuzane ikhubaze kwaye ife.

Kukho ezinye izinambuzane ezisetyenziselwa ukulima kunye nakwizityalo eziluhlaza. Icandelo layo eliphambili NguMaltodextrin. Isebenza ngokufunxa izinambuzane kunye neentsholongwane, zibogquma ngemiphunga yokuphefumla kwaye zibangele ukufa kwabo. Inokubangela ukufa nangokuncamathelisa izinambuzane kumphezulu wesityalo. Ithintela ukuhamba kwezinambuzane ezinamaphiko. Yiyo loo nto sikuthintela ukuhlala kwezinye iinxalenye zesityalo.

Amanye amayeza asekhaya

Ekuphathweni kwegadi yendalo kukho iindlela ezininzi esinokuzenza ekhaya, kwaye oko kuya kusinceda sibuyise impilo yeembiza zethu okanye igadi yethu, enje:

• Igalikhi: tyumza malunga nee-clove ezintathu zegalikhi uze uzifake kwilitha yamanzi ukucola onke amalungu esityalo esichaphazelekayo.
•  I-Basil: Esi sityalo sixabisekileyo sigxotha iimpukane ezimhlophe njengezinye. Tyala ezininzi kwigadi yakho.
• Umgibe weChromatic: izinambuzane ezininzi zinomdla kumbala othile. Kwimeko yesibetho esichaphazelayo, sityheli. Ukwenza umgibe, kuya kufuneka uthenge ikhadibhodi okanye iplastiki yalo mbala kwaye, ukuze ibenze banamathele, singasebenzisa ubusi okanye ioyile.

Oku kubandakanya ukwenza esethu isityalo, sisazi ukuba izinambuzane ezininzi zinobuthathaka ngombala otyheli kwaye zitsalelekile kuzo. Ezi zinambuzane ziya kuhamba ngombala otyheli ngaphandle kokukwazi ukumelana nazo. Ewe, ukusebenzisa olu lwazi, konke ekufuneka sikwenzile kukusebenzisa eli thuba ukuze sibabambe ukuze bangabaleki kwaye benzakalise izityalo zethu.

Kule nto, sinokusebenzisa nayiphi na into ebenza banamathele kunye njengeglu, ubusi, njl. Kufuneka sazi ukuba xa sisebenzisa iglu esetyenziselwa iimpuku singenza ukuba intaka ibambeke kwaye ife. Njengoko asiyifuni le nto, oku kungasentla okanye ioyile kunye nesepha zinokusetyenziswa njengeglu. Ngale ndlela, singabeka amadlavu amthubi afakwe kwezi zinto ukuze iimpukane ezimhlophe zitsaleleke kuzo kwaye masilawule ukuthoba isibetho ukuyenza ifikelele kumanqanaba amkelekileyo etumato kwaye ayivelisi monakalo.

Oku kungaphezulu ngokwaneleyo, ukusukela oko, kufuneka siphawule ukuba ayisiyiyo ingcuka emhlophe kuphela eya kutsalwa ngumbala omthubi, kodwa nezinye izinambuzane eziluncedo egadini.

Ndiyathemba ukuba ngezi ngcebiso ungasusa esi sinambuzane sicaphukisayo.
