Gutema amababi y'inyanya Tuta absoluta ifatwa nk'udukoko twangiza inyanya muri Egiputa.Bivugwa muri Egiputa kuva mu 2009, kandi byahise bihinduka kimwe mu byonnyi by’ibihingwa by’inyanya.Iyo livre igaburira imyunyu ngugu yagutse yamababi ya mesophyll, ibyangiritse bibaho, bigira ingaruka kubushobozi bwa fotosintetike yibihingwa bikagabanya umusaruro wabyo.
Abashakashatsi bo muri kaminuza ya Nangu bagaragaje udukoko dutanu twica udukoko dukoresheje uburyo bwo koga amababi mu bihe bya laboratoire, aribyo indoxacarb, abamectin + thiamethoxam, amimectin benzoate, fipronil na imidacloprid Ingaruka za liswi yuzuye umukara yera.
Abashakashatsi bagize bati: “Ibisubizo byerekana ko amimectin benzoate ari uburozi bwangiza udukoko, mu gihe imidacloprid ari uburozi buke.”
Mu rwego rwo kugabanya imikorere, imiti yica udukoko yapimwe itunganijwe kuburyo bukurikira: ampicillin benzoate, fipronil, abamectin + thiamethoxam, indoxacarb na imidacloprid.Indangagaciro LC50 ihuye nyuma yamasaha 72 yari 0.07, 0.22, 0.28, 0.59 na 2.67 ppm, mugihe LC90 yari 0.56, 3.25, 1.99, 4.69 na 30.29 ppm.
Abashakashatsi banzuye bati: “Ubushakashatsi bwacu bugaragaza ko enamostine benzoate ishobora gukoreshwa nk'urwego rwiza muri gahunda yo gucunga neza udukoko.”

Urimo kwakira idirishya rya pop-up kuko aribwo bwa mbere usuye kurubuga rwacu.Niba ukomeje kwakira ubu butumwa, nyamuneka ushoboze kuki muri mushakisha yawe.
