SayenziDaily (May 8, 2012) -Muzvinafundo wezvekudyara paUniversity yeCalifornia, Riverside akaona fungus yakabatana nebazi rekufa uye kudzikira kwakawanda kweavocado yekuseri kwemba nemiti yenzvimbo munzvimbo dzinogara vanhu dzeLos Angeles County.
Iyo fungus rudzi rutsva rweFusarium. Masayendisiti ari kushanda kuti aratidze kuzivikanwa kwayo chaiko. Inotapurirwa neTea Shot Hole Borer (Euwallacea fornicatus), anbrosia beetle idiki idiki pane sesame. Chirwere chainoparadzira chinonzi "Fusarium dieback."
"Chipembenene ichi chakawanikwawo muIsrael uye kubva muna 2009, kusanganiswa kwebeetle-fungus kwakakuvadza zvakanyanya pamiti yemakotapeya ikoko," akadaro Akif Eskalen, chiremba wezvekudyara UC Riverside, uyo ane lab akacherechedza fungus.
Kusvika pari zvino, Tea Shot Hole Borer yakashumwa pamhando gumi nesere dzezvirimwa pasi rose, kusanganisira avocado, tii, citrus, guava, lychee, mango, persimmon, pomegranate, macadamia uye silk oak.
Eskalen akatsanangura kuti bete nefungus zvine hukama hwesymbiotic.
“Apo bete rikachera mumuti, rinopinza chirimwa chacho jekiseni nefungus rarinotakura mumuromo maro,” akadaro. “Funga iyi inobva yarwisa matsinga emuti, ichikanganisa kuyerera kwemvura uye kudya kunovaka muviri, zvozokonzera kufa kwebazi. Makonye ezvipembenene anogara mumatura mukati memuti uye anodya howa.”
Kunyange zvazvo bete yakatanga kuonekwa muLos Angeles County muna 2003, mishumo yekukanganisa kwayo pahutano hwemuti haina kucherechedzwa kusvika munaFebruary 2012, apo Eskalen akawana bhete uye fungus pamuti weavocado wekuseri unoratidza zviratidzo zvekufa muSouth Gate, Los. Angeles County. Agricultural Commissioner weLos Angeles County neCalifornia Food and Drug Administration vakasimbisa kuzivikanwa kwebete.
"Iyi ndiyo fungus imwechete yakakonzera kufa kwekotapeya muIsrael," akadaro Eskalen. "California Avocado Commission iri kunetsekana nekuparara kwehupfumi nefungus iyi kuindasitiri yemuno muCalifornia.
“Parizvino, tiri kukumbira varimi vebindu kuti vatarise miti yavo uye vatiudze kana paine zviratidzo zvefungus kana bete,” vakadaro. “Zviratidzo zviri muavocado zvinosanganisira kuoneka kweupfu huchena hunobuda muhupfu pamwe chete neburi rinobuda nebete riri pamakwati ehunde nemapazi makuru emuti. Iyi exudate inogona kuoma kana kuita seyakanyorova.
Chikwata chemasaenzi eUCR chakaumbwa kuti chidzidze Fusarium dieback muSouthern California. Eskalen naAlex Gonzalez, mazvikokota wemumunda, vari kutoita ongororo kuti vaone kuti utachiona hwebete hwakakura sei uye kuti fungus ingangove yakadini mumiti yemakotapeya nezvimwe zvinomera zvinotambira. Richard Southamer, purofesa wezvipembenene, uye Paul Rugman-Jones, imwe nyanzvi yezvezvipembenene, vari kuongorora biology uye majini echipembenene.
Veruzhinji vanogona kuzivisa nezvekuonekwa kweTea Shot Hole Borer uye zviratidzo zveFusarium dieback nekufona (951) 827-3499 kana email aeskalen@ucr.edu.
