A process for the prevention of infestation by Ixodid ticks, or for the control or eradication of infestations of Ixodid ticks, which process comprises applying to the media to be protected or to the infested media an effective amount of a composition comprising as active ingredient a thienopyrimidine derivative of general formula I: ##STR1## xwherein R.sup.1 is chosen from alkyl optionally substituted with hydroxy, methoxy, cycloalkyl, aryl, heteroaryl, and heterocycloalkyl groups; alkenyl; alkynyl; cycloalkyl; R.sup.3 is chosen from hydrogen, alkyl and acyl; or R.sup.1 and R.sup.3 together form a saturated or unsaturated alkylene or heteroalkylene bridging group; R.sup.2 is chosen from hydrogen, hydroxy, mercapto, halo, cyano, optionally substituted-amino, optionally substituted hydrazino, alkyl, alkenyl, alkynyl, alkoxy, alkylthio, cycloalkyl, aralkyl, aryl and trifluoromethyl; R.sup.5 and R.sup.6 are independently chosen from hydrogen, optionally substituted alkyl, halogen and aryl; or R.sup.5 and R.sup.6 together form a saturated alkyl bridging group; or an optical isomer thereof; or a tautomer thereof; or a salt thereof; and a carrier therefor.
一种预防蜱虫侵袭、控制或根除蜱虫侵袭的方法,该方法包括向需要保护或已被侵袭的介质中施加有效量的含有噻唑嘧啶衍生物的组合物,该噻唑嘧啶衍生物的一般式为I:##STR1## 其中,R1选自烷基,该烷基可以选择性地被羟基、甲氧基、环烷基、芳基、杂芳基和杂环烷基取代;烯基;炔基;环烷基;R3选自氢、烷基和酰基;或者R1和R3一起形成饱和或不饱和的烷基或杂烷基桥连基;R2选自氢、羟基、巯基、卤素、氰基、可以选择性地取代的氨基、可以选择性地取代的肼基、烷基、烯基、炔基、烷氧基、烷硫基、环烷基、芳基、芳基烷基和三氟甲基;R5和R6独立地选自氢、可以选择性取代的烷基、卤素和芳基;或者R5和R6一起形成饱和的烷基桥连基;或其光学异构体;或其互变异构体;或其盐;以及载体。
