Pfupiso

DEET (Chirungu diethylmethylbenzamide), yakapfupikiswa seDEET, zita remakemikari ndi diethyltoluamide, ibhuku remakemikari rinodzinga zvipembenene zvakasiyana-siyana. Rine simba rekudzivirira zvipembenene zvakasiyana-siyana zvinoruma munzvimbo dzakasiyana-siyana uye rinogona kudzinga zvipembenene zvinoruma. Nhunzi, midges, nhunzi nhema, chiggers, nhunzi dzemhara, inda, unyunyu, nhunzi dzemabhiza, umhutu, nhunzi dzejecha, unyunyu, nhunzi dzakagadzikana nezvikwekwe.

DEET yakagadzirwa uye yakapihwa patent neUS Department of Agriculture panguva yeHondo Yenyika II. Mushonga uyu wakasarudzwa semushonga unodzinga umhutu kuti ushandiswe nemauto eUS muna 1946. Wakanyoreswa neUS Environmental Protection Agency semushonga unodzinga zvipembenene muna 1957 uye wakatanga kushandiswa nevanhuwo zvavo. Pakutanga waishandiswa semushonga unouraya zvipembenene mumapurazi. Gare gare, hurumende yeUS yakanyorera kushandiswa kwawo panguva yehondo, kunyanya muVietnam neSoutheast Asia. Sekureva kwehuwandu hweUS Environmental Protection Agency, gore rega rega Chemicalbook Vanenge 40% vekuAmerica vanoshandisa mushonga unodzinga zvipembenene une DEET, unoshandiswa nevanhu vanosvika mamiriyoni mazana maviri pasi rose. Mumakore makumi mana apfuura, zvidzidzo zvakaitwa nemayunivhesiti anopfuura zviuru makumi maviri zvakaratidza kuti DEET ndiyo mushonga unodzinga zvipembenene wakachengeteka uye unoshanda zvakanyanya pamusika. Mushonga unodzinga zvipembenene wakakura. World Health Organisation inokurudzirawo kushandiswa kwemishonga inodzinga zvipembenene ine DEET kudzivirira zvipembenene zvinotakura zvipembenene. Unowanzo sanganiswa nezvimwe zvipembenene, asi chepfu yawo inowedzera kana ikasanganiswa nemishonga inouraya zvipembenene inonzi carbamate.
