Uphononongo olutsha lwabemi bentsimi yeencukuthu ezininzi eziqhelekileyo (i-Cimex lectularius) yafumanisa ukuba abantu abathile abavakalelwa kangako kwizinambuzane ezimbini ezisetyenziswa ngokuqhelekileyo.
Iingcali zokulawula izinambuzane zilumkile ukulwa nobhubhane oqhubekayo weencukuthu ngenxa yokuba baye bamkela isethi ebanzi yamanyathelo okunciphisa ukuthembela kwabo kulawulo lwemichiza, kuba uphando olutsha lubonisa ukuba iincukuthu ziyakwazi ukumelana nezinambuzane ezimbini ezisetyenziswa ngokuqhelekileyo.Iimpawu zakwangoko.
Kuphononongo olupapashwe kule veki kwi-Journal ye-Economic Entomology, abaphandi kwiYunivesithi yasePurdue bafumanisa ukuba kwi-10 yeebhugi zebhedi eziqokelelwe entsimini, abantu be-3 babenovelwano kwi-chlorpheniramine.Uvakalelo lwe-5 yabantu kwi-bifenthrin nayo yehla.
I-bug ye-bed bug eqhelekileyo (i-Cimex lectularius) ibonise ukuxhathisa okubonakalayo kwi-deltamethrin kunye nezinye izitshabalalisi ze-pyrethroid, ekukholelwa ukuba sesona sizathu sokuphinda siphinde sibe sisitshabalalisi sasezidolophini.Enyanisweni, ngokutsho kwe-2015 Pest without Borders Survey eyenziwa nguMbutho weSizwe woLawulo lweZitshabalalisi kunye neYunivesithi yaseKentucky, i-68% yeengcali zokulawula izinambuzane zijonga iibhugi njengezona zinambuzane ezinzima kakhulu ukulawula.Nangona kunjalo, akukho zifundo eziye zenziwa ukuphanda ukuchasana okunokwenzeka kwi-bifenthrin (kunye ne-pyrethroids) okanye i-clofenazep (i-pyrrole insecticide), eyabangela ukuba abaphandi beYunivesithi yasePurdue baphande.
“Kwixesha elidlulileyo, iincukuthu ziye zabonisa ngokuphindaphindiweyo ukukwazi ukuphuhlisa ukuxhathisa kwiimveliso ezixhomekeke kakhulu kulawulo lwazo.Iziphumo zolu phononongo zikwabonisa ukuba iincukuthu zineendlela ezifanayo ekuphuhliseni ukuchasana ne-clofenazep kunye ne-bifenthrin.Ezi ziphumo kunye nembono yokulawulwa kokumelana ne-insecticide, i-bifenthrin kunye ne-chlorpheniramine kufuneka isetyenziswe ngokudibanisa nezinye iindlela zokuphelisa iibhugi zokulala ukuze zigcine ukusebenza kwazo ixesha elide.”
Bavavanya iincukuthu zebhedi ezili-10 eziqokelelwe kwaye zenza igalelo ngoochwephesha bolawulo lwezinambuzane kunye nabaphandi baseyunivesithi e-Indiana, New Jersey, Ohio, Tennessee, Virginia naseWashington DC, kwaye balinganisa iincukuthu ezibulewe zezi zinambuzane zingaphelanga iintsuku ezisi-7 zokuvezwa.ipesenti.Amayeza okubulala izinambuzane.Ngokubanzi, ngokusekwe kuhlalutyo lweenkcukacha-manani olwenziwayo, xa kuthelekiswa nabantu abachaphazeleka kwilabhoratri, amanani eencukuthu anesantya sokusinda esingaphezulu kwama-25% athathwa njengangenabungozi kangako kwizibulali-zinambuzane.
Okubangel 'umdla kukuba, abaphandi bafumene ulungelelwaniso phakathi kwe-clofenazide kunye ne-bifenthrin susceptibility phakathi kwe-bed bug populations, eyayingalindelekanga ngenxa yokuba i-insecticide ezimbini zisebenza ngeendlela ezahlukeneyo.UGundalka uthe uphando olongezelelweyo luyafuneka ukuze kuqondwe ukuba kutheni iincukuthu zebhedi zingachaphazeleki kancinci zinokumelana nokuvezwa kwezi zinambuzane, ngakumbi i-clofenac.Kuyo nayiphi na imeko, ukuthotyelwa kweendlela ezihlanganisiweyo zokulawula izinambuzane kuya kucothisa uphuhliso olongezelelweyo lokuxhathisa.
