1,2,4-Thiadiazole compounds represented by the formula (1) have excellent control activities against harmful arthropods:
wherein R1 represents C3-C7 alkynyl group optionally substituted one or more halogen atom(s); R2 a represents a halogen atom, a C1-C4 alkyl group, a C1-C4 haloalkyl group, a C1-C4 alkoxy group, a C1-C4 haloalkoxy group, a C1-C4 alkylthio group, a cyano group, or a nitro group, and n is an integer of 0 to 5, provided that, when n is an integer of 2 or more, respective R2s may be the same or different; A represents an oxygen atom, a sulfur atom, a single bond, a CR3R4 group, or NR5; R3 and R4 represent each independently a hydrogen atom or a C1-4 alkyl group; and R5 represent a hydrogen and the like.
式(1)所代表的1,2,4-噻二唑化合物对有害节肢动物具有优异的控制活性:其中,R1代表C3-C7炔基,可选地取代一个或多个卤素原子;R2a代表卤素原子、C1-C4烷基、C1-C4卤代烷基、C1-C4烷氧基、C1-C4卤代烷氧基、C1-C4烷硫基、氰基或硝基,n为0至5的整数,但当n为2或更多时,各自的R2a可以相同或不同;A代表氧原子、硫原子、单键、CR3R4基团或NR5;R3和R4各自独立地代表氢原子或C1-4烷基;R5代表氢等。
