TECHNICAL FIELD Fenazaquin is described in, for example, EP0326329A and can be produced by a process described therein. The present application is ?led claiming the priority of the In the pest control composition of the present invention, the Japanese Patent Application No. 2011-15971 1, the entire contents of which are herein incorporated by reference. weight ratio of etoxazole to fenazaquin is, for example, from The present invention relates to a pest control composition 500011 to 115000, from 50011 to 115000, from 30011 to and a pest control method. 114100, from 25011 to 114097, from 10011 to 11100, from 1611 to 1116 and from 113 to 1116. BACKGROUND ART The pest control composition of the present invention may be a simple mixture of etoxazole and fenazaquin. However, Etoxazole, 2-(2,6-di?uorophenyl)-4-[4-(1,1-dimethyl the pest control composition of the present invention is gen ethyl)-2-ethoxyphenyl]-4,5-dihydrooxazole) is known as an erally prepared by mixing etoxazole and fenazaquin and an active ingredient of a pest control agent (see, e.g., Patent Literature 1). inert carrier, and if necessary a surfactant and the other for Also, fenazaquin, 4-tert-butylphenethquuinazolin-4-yl mulation additives, and then formulating the mixture into a ether, is known as an active ingredient of a pest control agent formulation such as oil solution, emulsi?able concentrate, (see, e.g., Patent Literature 2). suspension concentrate, wettable powder, water dispersible granules, dusts, or granules. CITATION LIST 20 The pest control composition of the present invention con tains etoxazole and fenazaquin in a total amount of generally Patent Literature 0.01 to 90% by weight, preferably 0.1 to 80% by weight. Examples of the inert carrier include solid carriers, liquid Patent Literature 11 WO93/22297 carriers and gaseous carriers.
