I-1.DEET i-wide-spectrum ye-insect repellent ekwazi ukugxotha iimpukane ezihlabayo, i-midges, iimpukane ezimnyama, i-chiggers, i-deer flies, i-fleas, i-gnats, i-horse fly, i-mosquitoes, i-sand fly, i-flying flying, i-stable flyes kunye neentwala.Ukugxotha iingcongconi kwaphuhliswa kwaye kunelungelo elilodwa lomenzi weSebe lezoLimo lase-US ngexesha leMfazwe Yehlabathi II, kwaye yatyunjwa njengemveliso yokugxotha ingcongconi kumkhosi wase-US ngo-1946. Urhulumente wase-US wafaka isicelo sokusetyenziswa ngexesha lemfazwe, ngakumbi eVietnam kunye ne-Asia-mpuma ye-Asia.Umbutho wezeMpilo weHlabathi ukwacebisa ukuba kusetyenziswe izinto zokugxotha iingcongconi ukuze kuthintelwe ukuhlasela kwezinambuzane ezigcina izilwanyana.Ihlala ixutywa nezinye izitshabalalisi, kodwa ubuthi bayo buyanda xa ixutywe ne-carbamate insecticide.

I-2.Indlela yokusebenza ye-DEET ayikacaci kakuhle, ingcamango yokuqala kukuba ixhomekeke kwiphunga elithintelayo ukwenza inambuzane ekhupha igazi ivumba ukuchasana kwaye igweme ukusondela emzimbeni womntu, ukufezekisa umphumo wokuthintela ukuluma.Nangona kunjalo, kwafunyaniswa ukuba i-DEET inokuthintela impendulo ye-electrophysiological yeengcongconi kwi-lactic acid kunye ne-1-octen-3-ol compounds kunye nezinye izinto eziphambili zokubila komntu, ukufihla okanye ukuvala inkqubo ye-olfactory yeengcongconi kunye nokuthintela i-Chemicalbook ekuchongeni ixhoba elifanelekileyo.Emva koko, kwafunyaniswa ukuba i-DEET isebenza ngokuthe ngqo kwii-neurons ezivumbayo kwiintente zeengcongconi ukuvelisa iziphumo ezigxothayo kwaye ayivimbeli imbono yeengcongconi kwiikhemikhali ezifana ne-lactic acid, i-CO2 kunye ne-1-octen-3-ol.Uphononongo olutshanje luye lwafumanisa ukuba ukubophelela kwe-DEET kwiithagethi ezithile ze-molekyuli yinyathelo lokuqala le-biochemical ekuqapheliseni izinto zangaphandle, kodwa ezi ziphumo kufuneka ziqinisekiswe ngokulandelelana.

I-3.ebizwa nangokuthi i-DEET, i-N, i-N-Diethyl-3-methylbenzamide okanye i-diethyltoluamide, iyona nto ixhaphakileyo esebenzayo kwi-repellents yezinambuzane.Yioli etyheli kancinane ecetyelwe ukuba isetyenziswe kwisikhumba okanye kwimpahla, kwaye ibonelela ngokhuseleko kwiingcongconi, amakhalane, iintakumba, iichiggers, iileeches, kunye nezinambuzane ezininzi ezilumayo.Ungaza kwiphepha lethu ukufumana ngakumbi http://tnjchem.en.made-in-china.com
