BACKGROUND ART 10 [0002] Alkyl phenyl sulfide derivatives having a pest control effect are described in patent literatures 1, 2, 3, 4, 5 and 6. However, the compounds described in the patent literatures 1, 2, 3 and 4 are restricted to alkyl phenyl sulfide derivatives having no substituent group on the alkylthio group; the compounds described in the patent literature 5 are restricted to alkyl phenyl sulfide derivatives having certain substituents on the phenyl ring; and the compounds described in the patent literature 6 are restricted to alkyl phenyl sulfide derivatives having a 2-bromoethylthio group as a substituent group. 15 Thus, these patent literatures make no mention of an alkyl phenyl sulfide derivative having a substituent group other than bromine atom on the alkylthio group. [0003] The follow-up experiment made on the compounds described in the above patent literatures revealed that, despite the description made therein, the compounds have an insufficient effect to spider mites, have no effect to spider mites which have acquired chemical resistance, and accordingly have no sufficient control effect. 20 PRIOR ART LITERATURES Patent Literatures 25 [0004] Patent literature 1: JP-A-1975-29744 Patent literature 2: JP-A-1976-19121 Patent literature 3: JP-B-1982-35162 30 Patent literature 4: JP-A-1988-41451 Patent literature 5: JP-A-1992-312566 Patent literature 6: US Patent 3388167 DISCLOSURE OF THE INVENTION 35 Task to Be Achieved by the Invention [0005] Pest control agent applied to useful crops is desired to be a chemical agent which exhibits a sufficient pest control effect at a low dose when applied to soil or stem and leaf. Also, development of safer pest control agent is desired 40 because requirements for safety of chemical substance and its influence to environment are becoming stronger. Further, in recent years, the use of pest control agents such as insecticide, miticide and the like over many years have invited the appearance of pests which have acquired resistance to such pest control agents, and complete control of pests have become difficult. Furthermore, the use of pest control agents having high toxicity to humans and livestock has become a problem from the safety to workers and others. 45 [0006] Under such circumstances, the task of the present invention is to solve the above-mentioned problems of conventional pest control agents and provide a pest control agent superior in safety, control effect, residual effect, etc. (Means to solve the problems) 50 [0007] In order to develop a pest control agent having the above-mentioned desirable properties, the present inventors synthesized various alkyl phenyl sulfide derivatives and investigated their physiological activities earnestly. As a result, it was found that an alkyl phenyl sulfide derivative represented by the following general formulas [I] or [I’] (the derivative is hereinafter referred to as the present compound) has an excellent effect on various pests, particularly on spider mites represented by Tetranychus urticae, Tetranychus kanzawai, Panonychus citri, etc. A further research has led to the 55 completion of the present invention. [0008] The present invention is as follows.
