<p>There is provided an isoxazoline compound for use in controlling an animal ectoparasite. The compound is used for controlling an ectoparasite of dogs by orally administering an ectoparasite-controlling agent comprising as an active ingredient an isoxazoline compound represented by formula (I) : wherein X1 represents a halogen atom or a Cl-C3 haloalkyl, X2 represents a hydrogen atom, a halogen atom or a Cl-C3 haloalkyl, X3 represents a hydrogen atom or a halogen atom, Q represents, for example, Q1 or Q2. In the test examples, A1 represents R11- C(=O)-N(R12)-N(R13) -, where R11 is a cyclopropyl group, R12 and R13 are hydrogen atoms and R10 is a chlorine atom. A2 represents R23-N(R24)-C(=O)CH(R25)-N(R22)- C(=O)-, where R20 is a methyl group, R24 and R25 are hydrogen atoms and R23 is a 2,2,2-trifluoroethyl group. Further Q groups are specified in the main claim. The compound is given to a dog in a period from 30 minutes immediately before the start of feeding to 120 minutes after the end of feeding.</p> |
