    Abstract: PROBLEM TO BE SOLVED: To provide a novel crystalline transformation of fipronyl, and a method for producing said crystalline transformation, and also a composition for combating pests and parasites.SOLUTION: Use of a novel crystalline transformation IV of fipronyl of formula I below that exists in a triclinic crystalline system having center symmetric space group P-1. Said fipronyl is dissolved into acetone and crystallized to obtain crystalline transformation IV, and which is used, as it is (crystalline transformation IV), as a composition for controlling pests. High purity fipronyl of said crystalline transformation IV is a raw material for converting to crystalline transformation IV by further tempering the crystalline transformation IV at 90 to 100°C, or to crystalline transformation V by tempering at 100 to 130°C.
