A series of 14 new 3-[4(3H)-quinazolinone-2-yl)thiomethyl]-l,2,4-triazoles were prepared and characterized by elemental analyses, IR, ['HI NMR and mass spectral data. Four of the compounds showed insecticidal activity equivalent to that of malathion against the adult stage of the blow fly (Chrysorny
