Gooyaha caleenta yaanyada Tuta absoluta waxaa loo arkaa cayayaanka yaanyada ee ugu waxyeelada badan Masar.Waxaa laga soo sheegay Masar tan iyo 2009, waxayna si dhakhso ah u noqotay mid ka mid ah cayayaanka ugu waaweyn ee dalagyada yaanyada.Marka dirxiga ay ku quudiyaan macdanta la balaariyay ee caleemaha mesophyll, waxyeello ayaa dhacda, taas oo saameynaysa awoodda photosynthetic ee dalagyada waxayna yareysaa wax soo saarkooda.
Saynisyahano ka tirsan jaamacadda Nangu ayaa aqoonsaday shan sunta cayayaanka ah oo isticmaalaya habka qooynta caleen ee xaaladaha shaybaadhka, kuwaas oo kala ah indoxacarb, abamectin + thiamethoxam, amimectin benzoate, fipronil iyo imidacloprid Saamaynta buuxda ee dirxiga cadceedda madow.
Saynis yahanadu waxay yiraahdeen: "Natiijooyinka waxay muujinayaan in amimectin benzoate ay tahay sunta ugu badan ee cayayaanka, halka imidacloprid ay tahay sunta ugu yar."
Sida ay u kala horreeyaan hoos u dhaca waxtarka, sunta cayayaanka lagu tijaabiyey waxaa loo habeeyey sida soo socota: ampicillin benzoate, fipronil, abamectin + thiamethoxam, indoxacarb iyo imidacloprid.Qiimaha LC50 ee u dhigma 72 saacadood ka dib waxay ahaayeen 0.07, 0.22, 0.28, 0.59 iyo 2.67 ppm, halka LC90 qiyamku ahaa 0.56, 3.25, 1.99, 4.69 iyo 30.29 ppm.
Saynis yahanadu waxay soo gabagabeeyeen: "Cilmi-baadhisteenu waxay caddaynaysaa in enamostin benzoate loo isticmaali karo xarun wanaagsan oo ku jirta barnaamijka maaraynta dhamaystiran si loo xakameeyo cayayaankan."
