Allium Leaf Miner ikomoka mu Burayi, ariko yavumbuwe muri Pennsylvania mu 2015. Ni isazi ifite liswi zirisha ku bihingwa byo mu bwoko bwa Allium, harimo igitunguru, tungurusumu, n'amababi.
Kuva yagera muri Amerika, yakwirakwiriye i New York, Connecticut, Massachusetts, Maryland, na New Jersey kandi ifatwa nk'ikibazo gikomeye mu buhinzi.Itsinda ry’abashakashatsi bayobowe na Cornell bakoze ibizamini byo mu murima ku bintu 14 byangiza imiti yica udukoko kandi babishyira mu bikorwa bitandukanye kugira ngo basobanukirwe uburyo bwiza bwo kuvura.
Ibyavuye mu bushakashatsi byakozwe mu bushakashatsi bwasohotse ku ya 13 Kamena mu kinyamakuru “Ikinyamakuru cy’ubukungu Entomologiya” cyiswe “Umucukuzi w’imicungire ya Allium: Indwara zivuka n’udukoko twangiza ibihingwa bya Allium muri Amerika ya Ruguru.”
Itsinda ry’ubushakashatsi riyobowe n’umwanditsi mukuru Brian Nault, umwarimu wa entomologiya muri tekinoroji y’ubuhinzi ya Cornell, akaba n’umwe mu nzobere mu micungire y’udukoko twangiza amababi ya Allium muri Amerika, yavumbuye imiti myinshi yica udukoko twangiza imiti Ifite ingaruka nziza ku dukoko twangiza.
Nault yagize ati: “Ku mirima kama idakoresha ibikoresho byiza byo gucunga-imiti yica udukoko twangiza-ikibazo cya allium foliaricide gikunze kuba gikomeye.”
Phytomyza Gymnostoma (Phytomyza Gymnostoma) ifite ibisekuruza bibiri mumwaka, kandi abantu bakuru bagaragara muri Mata na Nzeri hagati.Mu ci, ibitunguru byinshi birakura, kandi habaho guhagarara hagati yizi nzinguzingo zombi, zituma imyaka ishobora guhunga udukoko.Mu buryo nk'ubwo, ibitunguru byibitunguru byabyimba vuba, bigatuma igihe cyibabi kidashobora kurisha neza.
Mu bacukura amabuye y'agaciro, ibihingwa bifite amababi y'icyatsi bibangamiwe cyane.Mu buraruko bushira ubuseruko bwa Reta zunzubumwe za Reta zunzubumwe za Reta zunzubumwe za Reta zunzubumwe za Reta zunzubumwe za Reta zunzubumwe za Reta zunzubumwe za Reta zunzubumwe za Reta zunzubumwe za Amerika.Imisozi yo mu gasozi imara ibisekuru bibiri irashobora guhinduka ikigega cyo gukura udukoko.
Ibinyomoro bitangira kurisha hejuru yikimera bikimukira mukibanza kugirango bizamuke.Ibinyomoro birashobora gusenya ingirangingo z'amaraso, bigatera indwara ya bagiteri cyangwa fungal kandi bigatera kubora.
Itsinda ry’ubushakashatsi ryagerageje ingamba zitandukanye zo gucunga hamwe nigitunguru, igitunguru nigitunguru kibisi muri Pennsylvania na New York muri 2018 na 2019. Gutera imiti yica udukoko (dimethylfuran, cyanocyanoacrylonitrile na spinosyn) nuburyo buhoraho kandi bunoze, bugabanya ibyangiritse kugera kuri 89% kandi kurandura udukoko kugera kuri 95%.Dichlorofuran na cyanocyanoacrylonitrile ikoreshwa na tekinike yo kuhira imyaka ntacyo ikora.
Indi miti yica udukoko (abamectin, paracetamol, cypromazine, imidacloprid, lambda cyhalothrin, methomyl na spinosyn) nayo yagabanije ubucucike bwa allium foliaricide.Spinosyn ikoreshwa mumizi yambaye ubusa cyangwa amacomeka kugirango ibikorwa bikorwe, bigabanye kwangiza udukoko nyuma yo guhindurwa 90%.
Nubwo abacukura igitunguru cya allium batarabera ikibazo cyibitunguru kugeza ubu, abashakashatsi nabahinzi bafite impungenge ko bishobora kuba ikibazo baramutse bakwega kandi bakimukira mu burengerazuba (nicyo gihingwa nyamukuru cyibitunguru).Nat yagize ati: “Iki cyahoze ari ikibazo gikomeye ku nganda z’ibitunguru zo muri Amerika.”
