Ucwaningo olusha lwezibalo zasensimini zezimbungulu ezimbalwa ezivamile (i-Cimex lectularius) luthole ukuthi abantu abathile abazweli kangako ezibulala-zinambuzane ezimbili ezivame ukusetshenziswa.
Ochwepheshe bokulawula izinambuzane bahlakaniphe ukulwa nobhadane oluqhubekayo lwezinambuzane zombhede ngenxa yokuthi bathathe isethi ebanzi yezinyathelo zokunciphisa ukuthembela kwabo ekulawuleni amakhemikhali, ngoba ucwaningo olusha lubonisa ukuthi izimbungulu zimelana nezibulala-zinambuzane ezimbili ezivame ukusetshenziswa.Izimpawu zakuqala.
Ocwaningweni olushicilelwe kuleli sonto ku-Journal of Economic Entomology, abacwaningi baseNyuvesi yasePurdue bathola ukuthi kwezingu-10 zezimbungulu eziqoqwe ensimini, abantu abangu-3 bazwela i-chlorpheniramine.Ukuzwela kwabantu abangu-5 ku-bifenthrin nakho kwehlile.
I-bug evamile yombhede (i-Cimex lectularius) ibonise ukumelana okukhulu ne-deltamethrin nezinye izibulala-zinambuzane ze-pyrethroid, okukholakala ukuthi ziyisizathu esiyinhloko sokuvuka kwayo njengesilokazana sasemadolobheni.Eqinisweni, ngokocwaningo lwango-2015 lwePest without Borders oluqhutshwa yiNational Association for Pest Management kanye neNyuvesi yaseKentucky, ama-68% ochwepheshe bokulawula izinambuzane babheka izimbungulu njengezinambuzane ezinzima kakhulu ukuzilawula.Kodwa-ke, azikho izifundo ezenziwe ukuze kuphenywe ukuthi kungenzeka yini ukumelana ne-bifenthrin (futhi i-pyrethroids) noma i-clofenazep (i-pyrrole insecticide), okwenza abacwaningi basePurdue University baphenye.
“Esikhathini esidlule, izimbungulu ziye zabonisa ngokuphindaphindiwe ikhono lokuthuthukisa ukumelana nemikhiqizo encike kakhulu ekulawuleni kwazo.Okutholwe kulolu cwaningo kubonisa nokuthi izimbungulu zinemikhuba efanayo ekuthuthukiseni ukumelana ne-clofenazep ne-bifenthrin.Lokhu okutholakele kanye nombono wokulawulwa kokumelana nezinambuzane, i-bifenthrin ne-chlorpheniramine kufanele isetshenziswe ngokuhambisana nezinye izindlela zokuqeda izimbungulu ukuze kugcinwe ukusebenza kwazo isikhathi eside.”
Bahlole izimbungulu ezingu-10 eziqoqwe futhi zanikelwa ochwepheshe bokuphatha izinambuzane nabacwaningi basenyuvesi e-Indiana, New Jersey, Ohio, Tennessee, Virginia naseWashington DC, futhi bakala izimbungulu ezibulewe yilezi zimbungulu zingakapheli izinsuku eziyi-7 zokuchayeka.iphesenti.Izibulala-zinambuzane.Ngokuvamile, ngokusekelwe ekuhlaziyeni kwezibalo okwenziwe, uma kuqhathaniswa nezibalo zaselabhorethri ezisengozini, izihlwele zezimbungulu ezinezinga lokusinda elingaphezu kuka-25% zibhekwa njengezingangenwa kalula yizibulala-zinambuzane.
Kuyathakazelisa ukuthi abacwaningi bathola ukuhlobana phakathi kwe-clofenazide kanye ne-bifenthrin phakathi kwabantu bezinambuzane zombhede, okwakungalindelekile ngoba lezi zinambuzane ezimbili zenza ngezindlela ezahlukene.UGundalka uthe ucwaningo olwengeziwe luyadingeka ukuze kuqondwe ukuthi kungani izimbungulu ezingangenwa kalula zingamelana nokuchayeka kulezi zinambuzane, ikakhulukazi i-clofenac.Kunoma yikuphi, ukuhambisana nezinqubo ezididiyelwe zokulawula izinambuzane kuzobambezela ukuthuthuka okuqhubekayo kokumelana.
