Uhlelo olusha lokufaka izibulala-zinambuzane lokulawula i-Colorado potato beetle.

Kulesi sihloko, uZsofia Sendre woMnyango Wezokwelapha Izinambuzane eMichigan State University ubhala ukuthi okushaizibulala-zinambuzane zilawula ngempumeleloi-Colorado potato beetle kanye nezinye izinambuzane eziningi zamazambane, okunikeza abalimi ithuluzi elisha eliwusizo lokulifaka ezinhlelweni zabo zokulawula ukumelana nezibulala-zinambuzane.

I-Colorado potato beetle isalokhu ingenye yezinambuzane zamazambane eziyinkinga kakhulu. Abalimi manje sebengasebenzisa i-Zivalgo (i-fiazolin, ubuchwepheshe be-prazoline), isibulala-zinambuzane esisha samaqabunga esinikeza ithuluzi elisha elibalulekile lokulawula i-Colorado potato beetle.
I-Zivalgo iyisibulala-zinambuzane se-Class 30, okusho ukuthi indlela esebenza ngayo ihlukile kweminye imithi yokubulala izinambuzane evunyelwe ukulawula i-Colorado potato beetle. Ngenxa yokuthi i-Colorado potato beetle sekuyisikhathi eside ithuthukisa ukumelana nemithi yokubulala izinambuzane, ukwengeza indlela entsha yokusebenza kubalulekile ekulawuleni ukumelana. Ukushintshanisa izinhlobo ezahlukene zemithi yokubulala izinambuzane ngesikhathi sokukhula kusiza ukugcina ukusebenza kahle kwemikhiqizo ekhona.

I-Zivalgo iyasebenza ngokumelene nazo zonke izigaba ze-Colorado potato beetle futhi ingasetshenziswa phakathi nenkathi yokukhula, kusukela ezinsukwini eziyi-14 ngaphambi kokuvuna. Kodwa-ke, emasimini lapho kwasetshenziswa khona izibulala-zinambuzane ngesikhathi sokutshala ukulawula ama-overwinters, i-Zivalgo ngokuvamile isetshenziswa kangcono ukulawula ukuvela kwabantu abadala ehlobo, okuvame ukuqala ekuqaleni kukaJulayi ezindaweni eziningi zaseMichigan.
Ukuze uvikele leli khemikhali elisha futhi unciphise ukukhula kokumelana, gwema ukusebenzisa i-Zivalgo ezitshalweni ezindala ezikhula ebusika nasehlobo ngesikhathi esifanayo.
