Mamiriro ekunze ari kuramba achipisa, uye panguva ino, umhutu huri kuwedzerawo.Sezvinozivikanwa, zhizha mwaka unopisa uye zvakare mwaka wepamusoro wekuberekesa umhutu.Mumamiriro okunze anoramba achipisa, vanhu vazhinji vanosarudza kubatidza mhepo inofefetera pamba kuti vadzivise, asi havagone kuichengeta navo zuva rose, kunyanya vana vasingakwanisi kugara pamba.Panguva ino, vanhu vakawanda vachasarudza kuendesa vana vavo kuhuni manheru, uko kune migwagwa ine mimvuri nenzizi duku dzokutamba nokutonhodza.Chiri kunetsa ndechekuti nguva ino ndipo panonyorwawo mosquito netwupembenene.Saka, tingadzivise sei nekudzora humhutu hunopinda muchirimo?Heano mamwe mazano ekudzinga umhutu.
Chekutanga, tinofanira kunzwisisa nzvimbo dzekuberekesa umhutu Yeuka kuti mvura inomira inobereka umhutu, uye kukura kwavo kunoenderana nemvura.Umhutu hunogona kukandira mazai uye kukura mumvura isingayereri, saka tinofanira kudzivisa kuora nemvura isingayerere kunze;Kunewo matsime emvura inonaya, matsime etsvina, kufambiswa kwemashoko, gasi, uye mamwe mapaipi emanisiparati ari mumigwagwa yemugero wemigero yemvura iri pasi pechivako chekugara, pamwe chete nematsime ekuunganidza mvura pasi pevhu;Uye nzvimbo dzakadai semadenga awnings.
Chechipiri, todzinga sei umhutu?
Patinotonhodza kunze manheru, tinofanira kupfeka mbatya dzine ruvara rwakajeka.Umhutu hunofarira zvipfeko zvemavara matema, kunyanya nhema, saka edza kupfeka dzimwe mbatya dzakareruka muzhizha;Umhutu haufariri hwema hunonhuwa, uye kuomesa ganda reorenji uye willow peel pamiviri yavo zvinogonawo kuita zvinodzinga umhutu;Edza kupfeka tirauzi neheti panze kuti udzikise ganda.Zvisinei, kana iwe ukapfeka zvakawanda, zvichange zvichipisa zvikuru, uye kunyange kupisa kunogona kuitika.Saka imwe nzira ndeyekupfapfaidza mushonga unodzinga mosquito, mosquito repellent, mvura inodzinga mosquito, etc. usati wabuda.Izvi hazvingobvumiri kuti upfeke zvipfeko zvaunoda, asiwo zvinokudzivirira kuti usarumwa neumhutu.
Zvisinei, chinokatyamadzwa nevanhu vakawanda ndechekuti tinofanira kusarudza sei mishonga inodzinga umhutu, zvinhu zvipi zvisingakuvadzi mumuviri wemunhu, uye zvinogona kushandiswa nevacheche?Parizvino, zvakasimbiswa nesainzi zvinoshanda zvekudzinga umhutu zvinosanganisira DEET uye ethyl butylacetylaminopropionate (IR3535).
Kubva kuma1940,DEETyave ichirangarirwa seimwe yemishonga inobudirira zvikurusa yokudzinga umhutu, asi nheyo iri shure kwayo yave isina kujeka.Kusvikira chidzidzo chawana chakavanzika pakati peDEET neumhutu.DEET inogona kudzivirira umhutu kubva pakuruma vanhu.DEET haisi iyo isingafadzi kunhuwa, asi kana yakashandiswa paganda, mosquito haigoni kumira kunhuwa uye kubhururuka kure.Panguva ino, munhu wese achashamisika kana mushonga wehutu hunokuvadza muviri wemunhu?
N,N-Diethyl-m-toluamideine huturu hwakapfava, uye huwandu hwakakodzera hwezvigadzirwa hazvikonzere kukuvadza.Haina simba kune vanhu vakuru.Kune vacheche, zvinokurudzirwa kusaishandisa kune vacheche vari pasi pemwedzi mitanhatu, kwete kanopfuura kamwe pazuva kune vari pasi pemakore maviri, uye kwete kanopfuura katatu pazuva kune avo vari pakati pemakore maviri ne12.Iyo yakanyanya kusanganiswa yeDEET inoshandiswa nevana vari pasi pemakore gumi nemaviri ndeye 10%.Vana vari pasi pemakore gumi nemaviri havafanirwe kushandisa DEET nguva dzose kweanopfuura mwedzi mumwe.Saka kuvacheche, mishonga inodzinga umhutu inoshandiswa inogona kutsiviwa ne ethyl butylacetylaminopropionate.Zvichakadaro, N,N-Diethyl-m-toluamide mhedzisiro yeamine inodzinga mosquito iri nani pane yeester inodzinga mosquito.
Ethyl butylacetylaminoproponatendicho chikamu chikuru chemishonga inodzinga umhutu zvakagadzirirwa vana.Kuenzaniswa neDEET, Ethyl butylacetylaminoproponate pasina mubvunzo haina muchetura, yakachengeteka, uye inodzinga tumbuyu.Ethyl butylacetylaminopropionate inoshandiswawo muFlorida Mvura uye zvimwe zvigadzirwa.Ethyl butylacetylaminopropionate haina kukodzera vanhu vakuru chete, asiwo kune vacheche.Nokudaro, zvinokurudzirwa kuti pakusarudza mishonga yekudzivirira mosquito yevana, zvinokurudzirwa kusarudza zvigadzirwa zvine ethyl butylacetylaminopropionate.
Wese anenge arumwa nehumhutu anofanirwa kunge akambosangana nazvo, uye hazvinyatsogadzikana kutarisana nemabhegi matsvuku uye akazvimba, kunyanya mudunhu rekumaodzanyemba.Zhizha parinosvika, dunhu rekumaodzanyemba rinokanganiswa nemamiriro ekunze, mvura ichinaya inoramba ichinaya uye migero inoberekesa umhutu.Nokudaro, shamwari dziri kumaodzanyemba dzinoda mishonga yekudzivirira umhutu zvakanyanya.Kana uine mimwe mibvunzo nezveethyl butylacetylaminopropionate, ndapota inzwa wakasununguka kutaura nesu uye tichafara kukushandira iwe!
