Isazi y'ibara (Lycorma delicatula) ni udukoko dushya dushobora gutera isi y'abahinzi b'inzabibu zo mu burengerazuba bwo hagati.
Bamwe mu bahinzi na banyiri amazu muri Pennsylvania, New Jersey, Maryland, Delaware, Virginie y’Uburengerazuba na Virginie bavumbuye uburyo SLF ikabije.Usibye inzabibu, SLF yibasira kandi ibiti byimbuto, hops, ibiti bigari n'ibiti by'imitako.Niyo mpamvu USDA yashoye miriyoni z'amadolari kugirango igabanye ikwirakwizwa rya SLF no kwiga ingamba zifatika zo kugenzura mu majyaruguru y'uburasirazuba bwa Amerika
Abahinzi b'inzabibu benshi muri Ohio bahangayikishijwe cyane na SLF kubera ko udukoko twabonetse mu ntara zimwe na zimwe za Pennsylvania ku mupaka wa Ohio.Abahinzi b'inzabibu mu zindi ntara zo mu burengerazuba bwo hagati ntibashobora kuruhuka kuko SLF ishobora kugera mu zindi ntara byoroshye na gari ya moshi, imodoka, ikamyo, indege n'ubundi buryo.
Kuzamura imyumvire y'abaturage.Ni ngombwa kuzamura imyumvire ya SLF muri leta yawe.Kubuza SLF kwinjira muri leta yawe burigihe ninzira nziza.Kubera ko tudafite abantu babarirwa muri za miriyoni muri Ohio barwanya iki cyorezo, inganda zinzabibu za Ohio zatanze amadorari agera ku 50.000 mu iperereza rya SLF n’ubukangurambaga bukangurira abaturage.Indangamuntu ya SLF yacapishijwe kugirango ifashe abantu kubona udukoko.Ni ngombwa gushobora kumenya ibyiciro byose bya SLF, harimo ubwinshi bwamagi, bidakuze kandi bikuze.Nyamuneka sura iyi link https://is.gd/OSU_SLF kugirango ubone agatabo kamakuru kerekeye kumenyekanisha SLF.Tugomba gushaka SLF no kuyica vuba bishoboka kugirango ikwirakwize.
Kuraho igiti cya paradizo (Ailanthus altissima) hafi yumuzabibu."Igiti cya paradizo" nicyo SLF ikunda cyane, kandi kizahinduka ikiranga SLF.SLF imaze gushingwa aho, bazahita babona imizabibu yawe batangire kuyitera.Kubera ko Igiti cyo mu kirere ari igihingwa gitera, kuyikuraho ntacyo bizatwara umuntu.Mubyukuri, abantu bamwe bita "Igiti cyo mwijuru" "umudayimoni wihishe."Nyamuneka reba urupapuro rwukuri kugirango umenye uburyo bwo kumenya no gusiba burundu igiti cyijuru mumurima wawe.
SLF = kwica inzabibu nziza?SLF ni igihingwa, ntabwo ari isazi.Ifite igisekuru umwaka.SLF y'abagore itera amagi mugwa.Amagi arera mu mpeshyi yumwaka wa kabiri.Nyuma ya incububasi na mbere yo gukura, SLF yahuye na instar ya kane (Leach et al., 2019).SLF isenya imizabibu yinyo yonsa umutobe wa floem yikibabi, umugozi nigiti.SLF ni umururumba.Nyuma yo gukura, barashobora kuba benshi cyane muruzabibu.SLF irashobora guca intege cyane imizabibu, bigatuma imizabibu ishobora kwibasirwa nibindi bintu bitera impagarara, nk'imbeho ikonje.
Bamwe mu bahinzi b'inzabibu barambajije niba ari byiza gutera imiti yica udukoko ku mizabibu niba bazi ko idafite SLF.Nibyiza, ibyo ntabwo ari ngombwa.Uracyakeneye gutera inyenzi zinzabibu, inyenzi zo mubuyapani nisazi zimbuto.Twizere ko dushobora kubuza SLF kwinjira muri leta yawe.Nyuma ya byose, uracyafite ibibazo bihagije.
Bite ho mugihe SLF yinjiye muri reta yawe?Nibyiza, abantu bamwe mubashinzwe ubuhinzi muri leta yawe bazagira ubuzima bubi.Twizere ko bashobora guhanagura mbere yuko SLF yinjira muruzabibu rwawe.
Bite ho mugihe SLF yinjiye muruzabibu rwawe?Noneho, inzozi zawe zizatangira kumugaragaro.Uzakenera ibikoresho byose mumasanduku ya IPM kugirango wirinde udukoko.
SLF ibice by'amagi bigomba gukurwaho hanyuma bigasenywa.Lorsban yasinziriye cyane (rif ifite uburozi, Corteva) ifite akamaro kanini mu kwica amagi ya SLF, naho JMS Stylet-Oil (amavuta ya paraffine) ifite umubare muto wo kwica (Leach et al., 2019).
Imiti myinshi yica udukoko irashobora kurwanya SLF nymphs.Imiti yica udukoko hamwe nibikorwa byinshi byo gukomanga bigira ingaruka nziza kuri nymphs ya SLF, ariko ibikorwa bisigaye ntabwo byanze bikunze bisabwa (urugero, Zeta-cypermethrin cyangwa karbaryl) (Leach et al., 2019).Kubera ko igitero cya SLF nymphs gishobora kuba hafi cyane, kuvura birashobora kuba ngombwa.Porogaramu nyinshi zirashobora gukenerwa.
Nk’uko ubushakashatsi bwakozwe na kaminuza ya leta ya Penn bubitangaza, abantu bakuru ba SLF bashobora gutangira kugaragara mu ruzabibu mu mpera za Kanama, ariko bashobora kuhagera bitarenze Nyakanga.Imiti yica udukoko isabwa kurwanya abantu bakuru ba SLF ni difuran (Scorpion, Gowan Co.; Venom, Valent USA), bifenthrin (Brigade, FMC Corp.; Bifenture, UPL), na thiamethoxam (Actara, Syngenta).Da), Carbaryl (Carbaryl, Sevin, Bayer) na Zeta-Cypermethrin (Mustang Maxx, FMC Corp.)

SLF ni udukoko twangiza.Noneho uzi icyo gukora kugirango uve muri leta, nuburyo bwo kuyobora SLF niba bibabaje udashobora kuyibona muruzabibu.
