Ongororo nyowani yehuwandu hwemumunda yezvipembenene zvakajairwa pamubhedha (Cimex lectularius) yakawana kuti mamwe marudzi haanyanyi kunzwa kune maviri anowanzo shandiswa.
Vanamazvikokota vekudzivirira zvipembenene vane hungwaru kurwisa denda rinoramba riripo retsikidzi nekuti vakatora matanho akakwana ekuderedza kuvimba kwavo nemishonga yemakemikari, nekuti tsvakiridzo itsva inoratidza kuti tsikidzi dzinoshingirira kumishonga miviri inowanzoshandiswa.Zviratidzo zvekutanga.
Muchidzidzo chakaburitswa svondo rino muJournal of Economic Entomology, vaongorori vepaPurdue University vakawana kuti kubva mugumi nhova dzemibhedha dzakaunganidzwa mumunda, vanhu vatatu vaive nehanya nechlorpheniramine.Kunzwa kwevanhu ve5 kune bifenthrin kwakadererawo.
The common bed bug (Cimex lectularius) yakaratidza kuramba kwakanyanya kune deltamethrin nemamwe mishonga yepyrethroid, iyo inotendwa kuti ndicho chikonzero chikuru chekudzoka kwayo sechipembenene chemudhorobha.Sezvineiwo, maererano ne2015 Pest without Border Survey yakaitwa neNational Association for Pest Management uye University of Kentucky, 68% yenyanzvi dzekutarisira tupukanana dzinoona tsikidzi sechipembenene chakaoma kudzora.Zvisinei, hapana zvidzidzo zvakaitwa kuti zviongorore zvinogona kuramba bifenthrin (zvakare pyrethroids) kana clofenazep (insecticide yepyrrole), izvo zvakaita kuti vatsvakurudzi vePurdue University vaongorore.
"Munguva yakapfuura, tsikidzi dzakaratidza kakawanda kugona kusimudzira kurwisa kune zvigadzirwa zvinonyanya kutsamira pakutonga kwavo.Zvakawanikwa zvechidzidzo ichi zvinoratidzawo kuti tsikidzi dzine maitiro akafanana mukukura kwekuramba clofenazep uye bifenthrin. "Izvi zvakawanikwa uye kubva pakuona kwekudzivirira kwezvipembenene, bifenthrin uye chlorpheniramine inofanira kushandiswa pamwe chete nedzimwe nzira dzekubvisa zvipembenene zvepabhedha kuchengetedza kushanda kwavo kwenguva yakareba.”
Vakaedza tsikidzi gumi dzemibhedha dzakaunganidzwa uye dzakapihwa nenyanzvi dzekutarisira tumbuyu uye vaongorori vepayunivhesiti muIndiana, New Jersey, Ohio, Tennessee, Virginia neWashington DC, uye vakayera tsikidzi dzakaurayiwa netsikidzi mukati memazuva manomwe ekuonekwa.muzana.Mishonga yezvipembenene.Kazhinji, zvichibva pawongororo yenhamba yakaitwa, zvichienzaniswa nehuwandu hwevanhu vemurabhoritari, huwandu hwezvipembenene zvine mwero wekurarama unodarika 25% hunoonekwa sevasingatani kubatwa nemishonga yezvipembenene.
Sezvineiwo, vatsvakurudzi vakawana kuwirirana pakati pe clofenazide uye bifenthrin susceptibility pakati penhokwe dzemubhedha, izvo zvakanga zvisingatarisirwi nokuti maviri ezvipembenene anoita nenzira dzakasiyana.Gundalka akataura kuti kumwe kutsvagisa kunodiwa kuti unzwisise kuti sei tsikidzi dzemubhedha dzisingabatike dzichigona kumira kuratidzwa kune izvi zvipembenene, kunyanya clofenac.Chero zvazvingava, kutevedzera maitiro akabatanidzwa ekudzivirira zvipembenene kunononoka kuwedzera kukura kwekudzivisa.
