Kaminuza ya Pennsylvania Park-Itsinda mpuzamahanga ry’abashakashatsi bavuze ko inyenzi z’inyenzi zifite amahembe maremare yo muri Aziya zashyizeho ibimenyetso byihariye bya feromone hejuru y’igiti kugira ngo bikurura abagabo aho biherereye.Ubu buvumbuzi bushobora kuganisha ku guteza imbere igikoresho cyo kurwanya udukoko twangiza, twibasira amoko y'ibiti agera kuri 25 muri Amerika.
Kelly Hoover, umwarimu wigisha ibijyanye na entomologiya muri kaminuza ya Leta ya Penn, yagize ati: “Kubera inyenzi zifite amahembe maremare yo muri Aziya, ibiti by'ibiti ibihumbi n'ibihumbi byaciwe i New York, Ohio, na Massachusetts, ibyinshi muri byo bikaba ari ibishushanyo.”“Twabimenye.Feromone ikorwa n’igitsina gore cy’ubwoko irashobora gukoreshwa mu kurwanya udukoko. ”
Abashakashatsi batandukanije kandi bamenya imiti ine uhereye ku nyenzi z’umwimerere kandi zihuza inyenzi zifite amahembe maremare yo muri Aziya (Anoplophora glabripennis), nta na kimwe muri byo cyabonetse mu bisobanuro by’igitsina gabo.Basanze inzira ya feromone irimo ibice bibiri byingenzi-2-methyldocosane na (Z) -9-triecosene-na bibiri bito- (Z) -9-pentatriene na (Z) -7-pentatriene.Itsinda ry’ubushakashatsi ryasanze kandi buri cyitegererezo cy’ibirenge cyarimo ibice bine byose bigize imiti, nubwo ingano n’ubunini bizatandukana bitewe n’uko umukobwa ari isugi cyangwa abo bashakanye ndetse n’imyaka y’umugore.
Twabonye ko abagore bambere batazatangira gutanga umusaruro uhagije wuruvange rwa feromone-ni ukuvuga igipimo nyacyo cyimiti ine hagati yacyo-kugeza bafite iminsi igera kuri 20, ibyo bikaba bihuye nigihe byororoka. ”Hoover yagize ati: "Umugore amaze kuva mu giti cya Phyllostachys, bifata ibyumweru bibiri kugira ngo ugaburire amashami n'amababi mbere yo gutera amagi.
Abashakashatsi basanze iyo igitsina gore gitanze urugero rwiza nubunini bwa feromone hanyuma ukabishyira hejuru bagenda, byerekana ko byororoka, abagabo bazaza.
Hoover yagize ati: “Igishimishije ni uko nubwo feromone ikurura abagabo, irwanya inkumi.”Ati: “Ubu bushobora kuba uburyo bwo gufasha abagore kwirinda guhatanira abo bakundana.”
Byongeye kandi, abashakashatsi bamenye ko abagore bakuze mu mibonano mpuzabitsina bazakomeza gukora feromone umurizo nyuma yo gushyingiranwa, bemeza ko ari ingirakamaro ku bagabo no ku bagore.Abahanga mu bya siyansi bavuga ko mu gukomeza gukora feromone nyuma yo gushyingiranwa, igitsina gore gishobora gutuma umugabo umwe yongera gushyingiranwa, cyangwa bigatuma abandi bagabo babana nabo.
Melody Keener, inzobere mu bushakashatsi ku kigo cy’ubushakashatsi cy’amajyaruguru cya serivisi ishinzwe amashyamba muri Minisiteri y’ubuhinzi yo muri Amerika, yagize ati: “Abagore bazungukirwa no gushyingiranwa kwinshi, kandi bashobora no kungukirwa no gushyingiranwa n’umugabo igihe kirekire kuko iyi myitwarire kwiyongera.Birashoboka ko amagi yacyo arumbuka. ”
Ibinyuranye n'ibyo, umugabo yungukirwa no kwemeza ko intanga ze zonyine zikoreshwa mu gufumbira amagi y'umugore, ku buryo ingirabuzima fatizo zayo zonyine zanduzwa ibisekuruza bizaza.
Hoover yagize ati: “Ubu, dufite amakuru menshi yerekeye urukurikirane rw'imyitwarire igoye, hamwe n'ibimenyetso bya shimi n'amashusho n'ibimenyetso bifasha abo bashakanye kumenya no gufasha abagabo kongera kubona igitsina gore ku giti kugira ngo babarinde abandi.Ihohoterwa rikorerwa abagabo. ”.
Zhang Aijun, umuhanga mu by'imiti y’ubushakashatsi muri Minisiteri y’ubuhinzi n’ubuhinzi n’ubuhinzi muri Amerika, Ikigo cy’ubushakashatsi mu buhinzi cya Beltsville, Laboratoire y’udukoko twangiza udukoko twangiza udukoko twangiza udukoko, yavuze ko ibice bine byose bya feromone byakorewe hamwe kandi bigasuzumwa muri bioassay ya laboratoire activity ibikorwa by’imyitwarire.Synthetic trace feromone irashobora kuba ingirakamaro mugukemura inyenzi zitera mumurima.Zhang yatandukanye, amenya kandi ashushanya feromone.
Hoover yagize ati: “Ubwoko bwa feromone ya sintetike irashobora gukoreshwa ifatanije n’udukoko twangiza udukoko, kandi Ann Hajek ayiga muri kaminuza ya Cornell.”Ati: “Iyi fungus irashobora guterwa.Ku biti, iyo inyenzi zigenda hejuru yazo, zizakurura kandi zandure kandi zice ibihumyo.Mugukoresha feromone inyenzi zumugore zikoresha mugukurura igitsina gabo, turashobora gukurura inyenzi zabagabo kubica.Fungicide yica aho kuba Abagore bakize. ”
Iri tsinda rirateganya gukomeza kwiga mu kugerageza kumenya aho estrogene ikorerwa mu mubiri w’umuntu, uko umugabo ashobora kumenya feromone, igihe feromone ishobora kugaragara ku giti, kandi niba bishoboka guhuza izindi myitwarire muri ubundi buryo.Feromone.Iyi miti.

Abandi banditsi b'impapuro barimo Maya Nehme wo muri kaminuza ya Libani;Peter Meng, umunyeshuri urangije muri entomologiya muri kaminuza ya Pennsylvania;na Wang Shifa wo muri kaminuza ya Nanjing Forestry.
Inyenzi ndende yo muri Aziya ikomoka muri Aziya kandi ishinzwe gutakaza igihombo kinini cyigicucu cyagaciro nubwoko bwibiti byimbaho.Mu ntera yatangijwe muri Amerika, ikunda amakarita.
Inyenzi zo muri Aziya zifite amahembe maremare zirashobora kungukirwa no guhuza byinshi cyangwa guhuza igitsina gabo igihe kirekire, kuko iyo myitwarire yongerera amahirwe amagi yabo yera.
