Kushanda kwezvipembenene kurwisa umhutu kunogona kusiyanisa zvakanyanya panguva dzakasiyana dzezuva, uye pakati pemasikati neusiku. Chidzidzo cheFlorida chakawana kuti mosquito yemusango yeAedes aegypti inoshingirira permetrin yainyanya kubatwa nemushonga wezvipembenene pakati pehusiku nekubuda kwezuva. Kuramba kwakabva kwawedzera zuva rose, apo umhutu hwakanga huchinyanya kushanda, huchikwira pakuvira uye hafu yekutanga yeusiku.
Zvakabuda muongororo yakaitwa nevaongorori vepaUniversity of Florida (UF) zvine zvazvinorevakudzora zvipembenenenyanzvi, zvichivabvumira kushandisa mishonga yezvipembenene zvakanyanya, kuchengetedza mari, uye kuderedza kukanganisa kwavo kwezvakatipoteredza. "Takaona kuti mishonga yepamusoro yepermetrinzvaidiwa kuuraya umhutu na6 pm uye 10 pm Aya data anoratidza kuti permetrin inogona kushanda zvakanyanya kana ikashandiswa pakati pehusiku uye mambakwedza (6 am) kupfuura manheru (akapoteredza 6 pm)," akadaro Lt. Sierra Schloop, munyori-mubatanidzwa wechidzidzo. Chidzidzo chakabudiswa mu Journal of Medical Entomology muna February. mudzidzi wechiremba mune entomology paYunivhesiti yeFlorida pamwe naEva Buckner, Ph.D., munyori mukuru wechidzidzo ichi.
Zvinogona kuita sezvine musoro kuti nguva yakanakisa yekushandisa mushonga wezvipembenene kune umhutu ndipo pavanenge vachinyanya kurira, kubhururuka, uye kuruma, asi hazvisizvo nguva dzose, kana pakuedza nepermethrin, imwe yezviviri zvinonyanya kushandiswa kudzora mosquito muUnited States, iyo yakashandiswa muchidzidzo ichi. Mosquito yeAedes aegypti inoruma zvakanyanya mukati mezuva, mukati nekunze, uye inoshanda zvakanyanya maawa maviri mushure mekubuda kwezuva uye maawa mashoma zuva risati ravira. Chiedza chekugadzira chinogona kuwedzera nguva yavanogona kupedza murima.
Aedes aegypti (inowanzozivikanwa seyellow fever mosquito) inowanikwa kumakondinendi ese kunze kweAntarctica uye ndiyo vheji yemavhairasi anokonzera chikungunya, dengue, yellow fever, uye Zika. Yakave yakabatana nekubuda kwezvirwere zvinoverengeka muFlorida.
Nekudaro, Schluep akacherekedza kuti izvo ndezvechokwadi kune imwe mhando yeumhutu muFlorida zvinogona kunge zvisiri zvechokwadi kune mamwe matunhu. Zvinhu zvakasiyana-siyana, senge nzvimbo, zvinogona kukonzera kutevedzana kwegenome yeimwe mosquito kusiyana neiyo yeChihuahuas neGreat Danes. Naizvozvo, akasimbisa, zvakawanikwa muchidzidzo ichi zvinongoshanda kune yellow fever mosquito muFlorida.
Pane imwe caveat, zvisinei, akadaro. Zvakawanikwa zvechidzidzo ichi zvinogona kuitwa zvakazara kutibatsira kunzwisisa zviri nani mamwe marudzi ezvipenyu.
Kuwana kwakakosha kwechidzidzo kwakaratidza kuti mamwe majini anogadzira ma enzymes anogadzirisa uye anobvisa permethrin akabatwawo nekuchinja kwekusimba kwechiedza pamusoro peawa ye24. Ichi chidzidzo chakanangana nemajini mashanu chete, asi mhedzisiro inogona kuwedzeredzwa kune mamwe majini kunze kwechidzidzo.
"Tichifunga nezvatinoziva nezvemaitiro aya uye nezve mosquito biology, zvine musoro kuwedzera pfungwa iyi kupfuura aya majini uye nehuwandu hwesango," akadaro Schluep.
Kutaura kana kushanda kwemajini aya kunotanga kuwedzera mushure me2 pm uye kukwira murima pakati pe 6 pm na 2 am Schlup anonongedza kuti pamajini akawanda anobatanidzwa mukuita uku, mashanu chete ndiwo akadzidzwa. Anoti izvi zvinogona kunge zvichikonzerwa nekuti kana majini aya anenge achishanda nesimba, kubvisa muchetura kunowedzerwa. Ma enzymes anogona kuchengetwa kuti ashandiswe mushure mekunge kugadzirwa kwawo kwadzikira.
"Kunzwisiswa kuri nani kwekusiyana kwemasikati mukupikisa kwezvipembenene kunopindirana ne detoxification enzymes muAedes aegypti inogona kubvumira kushandiswa kwakananga kwemishonga inouraya zvipembenene panguva iyo kukanganisa kwakanyanya uye detoxification enzyme basa rakaderera," akadaro.
