Novel benzophenonehydrazone derivatives represented by the formula (I): wherein, R<1> is halogen; R<2> is hydrogen or C1-4 alkyl; R<3> is cyano, optically substituted C1-4 alkyl, C2-4 alkenyl, C3-4 alkynyl, C1-4 alkyl-carbonyl or C1-4 alkoxy-thiocarbonyl; R<4> is hydrogen, phenyl, optionally substituted C1-6 alkyl, optionally substituted C2-8 alkenyl, -CO-R<8>, -CO-O-R<9> or R<5> is hydrogen, formyl, phenyl, optionally substituted C1-8 alkyl, optionally substituted C2-8 alkenyl, optionally substituted C3-8 alkynyl, optionally substituted C1-8 alkyl-carbonyl, optionally substituted C1-6 alkyl-oxalyl, optionally substituted C1-8 alkoxy-carbonyl, optionally substituted C1-8 alkoxy-oxalyl, optionally substituted C3-8 cycloalkyl-carbonyl, optionally substituted C2-8 alkenyl-carbonyl or optionally substituted benzoyl; R<6> is hydrogen or halogen; R<7> is hydrogen, halogen or C1-2 alkyl, C1-4 alkyl-carbonyl or C1-4 alkoxy-thiocarbonyl; n is 0, 1 or 2, provided that n is 0 when R<3> is cyano, C1-4 alkyl-carbonyl or C1-4 alkoxy-thiocarbonyl, @ is a single bond of Anti form or of Syn form. The benzophenonehydrazone derivatives of the formula (I) have excellent insecticidal activities.
