Ubushakashatsi bushya bw’abaturage bo mu murima w’udusimba twinshi dusanzwe (Cimex lectularius) bwerekanye ko abaturage bamwe batumva neza udukoko tubiri dukunze gukoreshwa.
Inzobere mu kurwanya udukoko ni byiza kurwanya icyorezo gikomeje kwibasira uburiri kubera ko bafashe ingamba zihamye zo kugabanya kwishingikiriza ku kurwanya imiti, kubera ko ubushakashatsi bushya bwerekana ko udukoko tw’ibitanda turwanya udukoko tubiri dukunze gukoreshwa.Ibimenyetso byambere.
Mu bushakashatsi bwasohotse kuri iki cyumweru mu kinyamakuru cy’ubukungu bw’ubukungu, abashakashatsi bo muri kaminuza ya Purdue basanze mu bantu 10 b’ibitanda by’ibitanda byakusanyirijwe mu murima, abaturage 3 bumva chlorpheniramine.Imyumvire yabaturage 5 kuri bifenthrin nayo yagabanutse.
Indwara isanzwe yo kuryama (Cimex lectularius) yerekanye ko irwanya cyane deltamethrine nindi miti yica udukoko twitwa pyrethroid, bivugwa ko ari yo mpamvu nyamukuru yatumye yongera kuba udukoko two mu mujyi.Mubyukuri, ukurikije ubushakashatsi bwakozwe n’udukoko tw’umupaka utagira umupaka wa 2015 bwakozwe n’ishyirahamwe ry’igihugu rishinzwe kurwanya udukoko na kaminuza ya Kentucky, 68% by’inzobere mu kurwanya udukoko batekereza ko udukoko twangiza ari uburwayi bworoshye kurwanya.Icyakora, nta bushakashatsi bwakozwe kugira ngo hakorwe iperereza ku kurwanya indwara ya bifenthrine (na pyrethroide) cyangwa clofenazep (umuti wica udukoko twa pyrrole), byatumye abashakashatsi bo muri kaminuza ya Purdue bakora iperereza.
Yakomeje agira ati: “Mu bihe byashize, udusimba tw’ibitanda twerekanye inshuro nyinshi ubushobozi bwo guteza imbere kurwanya ibicuruzwa biterwa cyane n’ubugenzuzi bwabo.Ibyavuye muri ubu bushakashatsi byerekana kandi ko udusimba two ku buriri dufite inzira imwe mu iterambere ryo kurwanya clofenazep na bifenthrin. ”Ubu bushakashatsi hamwe no muburyo bwo kurwanya udukoko twica udukoko, bifenthrin na chlorpheniramine bigomba gukoreshwa hamwe nubundi buryo bwo gukuraho ibibyimba byo kuryama kugirango bikomeze gukora neza igihe kirekire.”
Bapimishije abantu 10 b’ibitanda byakusanyirijwe hamwe kandi batangwa ninzobere mu kurwanya udukoko n’abashakashatsi bo muri kaminuza muri Indiana, New Jersey, Ohio, Tennessee, Virginia na Washington DC, kandi bapima udusimba tw’ibitanda twishwe n’udukoko mu minsi 7 ishize.ijanisha.Imiti yica udukoko.Muri rusange, hashingiwe ku isesengura mibare ryakozwe, ugereranije n’abaturage ba laboratoire yanduye, abaturage b’udukoko bafite ubuzima burenga 25% bafatwa nkudashobora kwanduza imiti yica udukoko.
Igishimishije, abashakashatsi basanze isano iri hagati ya clofenazide na bifenthrin yanduye hagati yabaturage baburiri, ibyo bikaba bitari byitezwe kuko udukoko twica udukoko twombi dukora muburyo butandukanye.Gundalka yavuze ko hakenewe ubundi bushakashatsi kugira ngo dusobanukirwe n'impamvu udukoko tworoshye two kuryama dushobora kwihanganira kwandura iyi miti yica udukoko, cyane cyane clofenac.Ibyo ari byo byose, kubahiriza uburyo bwo kurwanya udukoko twangiza bizadindiza iterambere ryokurwanya.
