Wodula masamba a phwetekere Tuta absoluta amadziwika kuti ndi tizilombo towononga kwambiri ku Egypt.Zakhala zikunenedwa ku Egypt kuyambira 2009, ndipo posachedwa zakhala imodzi mwa tizirombo tambiri tomwe timawononga mbewu za phwetekere.Pamene mphutsi zimadya mchere wowonjezera wa masamba a mesophyll, zowonongeka zimachitika, zomwe zimakhudza mphamvu ya photosynthetic ya mbewu ndikuchepetsa zokolola zawo.
Asayansi pa yunivesite ya Nangu apeza mankhwala asanu ophera tizilombo pogwiritsa ntchito njira yonyowetsa masamba m'ma labotale, monga indoxacarb, abamectin + thiamethoxam, amimectin benzoate, fipronil ndi imidacloprid Zotsatira za mphutsi za whitefly zakuda.
Asayansiwo anati: “Zotsatira zake zikusonyeza kuti amimectin benzoate ndiye poizoni kwambiri ku tizilombo, pamene imidacloprid ndiyomwe ndi poizoni kwambiri.”
Potengera kuchepa kwa mphamvu, mankhwala ophera tizilombo omwe amayesedwa amakonzedwa motere: ampicillin benzoate, fipronil, abamectin + thiamethoxam, indoxacarb ndi imidacloprid.Miyezo yofananira ya LC50 pambuyo pa maola 72 inali 0.07, 0.22, 0.28, 0.59 ndi 2.67 ppm, pomwe ma LC90 anali 0.56, 3.25, 1.99, 4.69 ndi 30.29 ppm.
Asayansiwo anamaliza kuti: “Kafukufuku wathu akutsimikizira kuti enamostine benzoate ingagwiritsidwe ntchito ngati chigawo chabwino pa dongosolo lonse la kasamalidwe ka tizilombo toyambitsa matenda.”
