Ubwo Chris Schlegel yatangiraga gukora muri DS Cole, imwe mu macumbi manini y’ubucuruzi muri New Hampshire, ingamba zo kurwanya udukoko zari zoroshye: gutera imiti yica udukoko ku bintu byose igihe ibimenyetso bya mbere by’udukoko byagaragaye, hanyuma usubiremo buri cyumweru.
Chris Schlegel, umuhanga mu by'ubuhinzi muri DS Cole, yavuze ko uburyo bwo kurwanya udukoko twangiza ibidukikije bwasimbuye imiti yica udukoko nk'uburyo bwa mbere bwo kwirinda udukoko.
Iyi ngamba yasizwe inyuma, isimburwa n'ubundi buryo. Nk'igice cy'ubu buryo, Schlegel na bagenzi be bagabanyije inshuro n'umubare w'uburyo bwo kurwanya imiti bukoreshwa, ndetse no mu gihe bwakoreshwaga. Ntibagikoresha imiti yica udukoko, ahubwo bakoresha cyane cyane icyo bita "biological control", gikoresha inzira karemano mu kurwanya udukoko.
Mu buhinzi bukoresha ubuhinzi buciriritse, kurwanya ibinyabuzima bigerwaho ahanini binyuze mu gukoresha udukoko twica inyamaswa, tudateza ingaruka mbi ku bimera bitari ibyo birya. Abahinzi benshi nka DS Cole bakoresha uburyo bwo kurwanya ibinyabuzima kugira ngo bagabanye cyane ikoreshwa ry’imiti yica udukoko.
Buri koranabuhanga rishya rifite aba mbere baryo, ariko abahinzi benshi ba New Hampshire baracyakoresha imiti yica udukoko nk'uburyo bwabo bwonyine bwo kurwanya udukoko n'indwara. Jonathan Eba, inzobere mu buhinzi muri Kaminuza ya New Hampshire Extension Center, hamwe na bagenzi be, barimo Amber Venchesi-Wahl na Amy Papineau, barimo gukora ibishoboka byose kugira ngo impinduka mu kurwanya udukoko mu buryo bw'ibinyabuzima zorohe kandi zigire ingaruka nziza.
“Mu gihe natangaga ubufasha bwa tekiniki butaziguye ku bahinzi b’ibikomoka ku bimera hirya no hino muri leta, nagiye mbona buhoro buhoro ko bakeneye amabwiriza asobanutse neza kandi y’intambwe ku yindi,” ibi ni ibyatangajwe na Eba, umwe mu bagize itsinda bafasha abahinzi nka DS Cole. “Rero nateguye uburyo bwo gutangiza igenzura ry’ibinyabuzima. Ni gahunda ishobora gufasha abantu gutangira, hanyuma bakayihuza n’ibyo bakeneye mu myaka iri imbere.”
Akamashini ko gutangiza uburyo bwo kugenzura ibinyabuzima karimo amakuru ku binyabuzima runaka abahinzi bashobora gukoresha, ndetse n'ingamba zisanzwe zo gukoresha mu kurwanya udukoko. Uburyo bwa Eba busaba abahinzi gukurikirana buri gihe imikorere y'udukoko mu busitani bw'ubutaka—urugero, bakoresheje amakarita y'umuhondo afatanye kugira ngo bafate isazi zigenda hagati y'ibimera—no kumenya igihe udukoko twangiza dusohoka.
Gukoresha imiti yica udukoko ishobora kuba ikiri ngombwa, nubwo inshuro n'ingano byayo bizagabanuka.
Eba yagize ati: “Sinzi umuntu uhinga ibimera by’imitako adakoresheje imiti yica udukoko, ariko uburyo bwo kurwanya udukoko mu binyabuzima bugabanya cyane ingano y’imiti yica udukoko ikoreshwa.”
Mu 2008, Schlegel yatangiye kugerageza uburyo bwo kugenzura ibinyabuzima muri DS Cole. Yasohoye udukoko twaryaga udukoko twangiza gerbera. Utwo dukoko twagize ubudahangarwa ku miti yica udukoko, ndetse no gutera imiti buri cyumweru ntibyashoboye kutwica. Igerageza ryakomeje kwaguka kugira ngo rigenzure isazi z'umweru, zangizaga imyaka ya poinsettia. Mu myaka yakurikiyeho, DS Cole yatangiye guhinga ibyatsi mu nkono, kandi kugaragara kw'ibimera biribwa byatumye kugabanya ikoreshwa ry'imiti yica udukoko birushaho kuba ingenzi.
Schlegel yavuze ko kugenzura ibinyabuzima ari bwo buryo bwa mbere bw’ikigo mu kwirinda udukoko, kandi kurwanya imiti bizakoreshwa gusa iyo habayeho icyorezo cy’udukoko kandi nta mwanzi w’umwimerere uboneka ku isoko uhari.
Schlegel yavuze ko uburyo bwo kurwanya ibimera bufite ibyiza byinshi. Mbere na mbere, ni byiza ku bakozi 80 b’ubusitani ndetse n’ibidukikije. Izindi nyungu zirimo kuba ibimera byinshi byahinzwe na DS Cole bigurwa n’abandi bahinzi badashaka ko ibimera byavuwe n’imiti yica udukoko bibangamira ingamba zabo zo kurwanya ibimera. Amaherezo, nyuma yo kugabanya ikoreshwa ry’imiti yica udukoko, batangiye kubona udukoko gakondo ku mitego y’umuhondo. Utu dukoko twimuka ku buryo butunguranye, dukoreshwa mu buryo bwo kurwanya ibimera, twinjira mu madirishya afunguye, ikintu batashoboraga gukora mu gihe cy’ikoreshwa ry’imiti yica udukoko mu buryo bwa shimi.
Bite se ku bijyanye n'ibiciro? Ese DS Cole akoresha amafaranga menshi mu kugenzura ibinyabuzima kuruta ayo gukoresha mu buryo gakondo bwo gutera imiti? Schlegel yizera ko nta mpamvu yo kubara iyi mibare.
Chris Schlegel, umuhanga mu by'ubuhinzi muri DS Cole, yavuze ko amakarita y'umuhondo ashyirwa hirya no hino mu busitani kugira ngo akurikirane udukoko tudakenewe.
Schlegel yagize ati: “Ndatekereza ko ikintu cy’ingenzi kuri twe no ku bandi bahinzi benshi ari uko, urebye ibidukikije, umutekano w’abakozi bacu, inzuki, n’ibindi, ibi byose bigaragaza imbaraga.” “Ubu buryo bwagize icyo bugeraho cyane. Turacyahura n’udukoko, ariko dushobora kutwigarurira neza kurushaho. Niba utarakoresha imiti myinshi mbere, kurwanya udukoko biroroha cyane kuko udukoko tutarakomera.”
Schlegel yavuze ko ishami rishinzwe kwagura ibikorwa by’ubushakashatsi ari umufatanyabikorwa wizewe wa DS Cole mu kwagura ikoreshwa ry’uburyo bwo kurwanya udukoko mu buryo bw’ibinyabuzima. Impuguke mu gucunga udukoko zifasha ikigo mu gutegura ingamba zo kumenya udukoko no kurwanya udukoko, ndetse no gutegura ibiganiro bya buri kwezi by’amahugurwa n’inama zo kurwanya udukoko imbonankubone. DS Cole yemeye kwakira inama imwe nk’iyo mu Kwakira 2025.
Schlegel yagize ati: “Twabonye ubufasha bwinshi muri Kaminuza ya New Hampshire, kandi banakoranye n’abantu benshi bazi byinshi.”
Eba yagize ati: “Imwe mu ntego zanjye ni ugutangaza ko ingano y’imiti yica udukoko ikoreshwa ku bihingwa by’imitako muri New Hampshire yagabanutse bitewe no kurwanya udukoko mu buryo bw’ibinyabuzima.”
Niba amazu yororerwamo inyamaswa yo muri New Hampshire ashobora gukoresha uburyo bwo kurwanya udukoko mu buryo bw’ibinyabuzima aho gukoresha imiti yica udukoko mu gihe kizaza, aya masosiyete azabasha gutanga umusaruro mwiza, kurinda abakozi bawo umutekano, kandi ashobora no kugirira akamaro ibidukikije.
