Abstract the present Invention relates to novel compounds of the formula I and azolobenzazina the n-oxides, stereoisomers,Taut u00f3meros and acceptable salts in Agriculture and Veterinary.(i) where C1 or C2 is c o C CH CH N A1 or A2 is c n, C N (R2), (R3), o, s or C (R4, R5)； and A3 is n, o, S, N (r6), C (R7) or C (R8,R9)； A4 is n or C (n； R) is A5 or A6 is C (R) or C (n； R), where one or two non adjacent links in the five Member Ring formed by C1, C2, A1, A2 and A3 are double Bonds,While the others are simple links.Whenever the link between A1 and A2 or A1 and C1 between the link or the link between A2 and A3 or link between C1 and C2 or C2 is the link between A3 and a double Bond.It also provided that at least one of A1, A2 and A3, N (R3) or N (r6), where r, r, R1, R2, R3, R4, R5, R6, R7, R8 and R9 are as defined in the claims.The compounds of the formula (i), as well as the n-oxides, stereoisomers, and taut u00f3meros acceptable salts in Agriculture and Veterinary Medicine,They are useful to combat and control pests Pest Invertebrates, particularly Arthropods and nematodes.The Invention also relates to a method for controlling Invertebrate pests by the use of these compounds.Vegetative propagation materials and Agricultural and Veterinary composition comprising these compounds.RESUMEN La presente invención se refiere a compuestos de azolobenzazina novedosos de la Fórmula I y a los N-óxidos, estereoisómeros, tautómeros y las sales aceptables en la agricultura o veterinaria de aquellos. (I) en donde C1 es C o CH C2 es C o CH A1 es N o C A2 es N, C(R2), N(R3), O, S o C(R4,R5)； y A3 es N, O, S, N(R6), C(R7) o C(R8,R9)； A4 es N o C(R)； A5 es N o C(R)； A6 es N o C(R)； en donde uno o dos enlaces no adyacentes en el anillo de 5 miembros formado por C1, C2, A1, A2 y A3 son enlaces dobles, mientras que los otros son enlaces simples, siempre que el enlace entre A1 y A2 o el enlace entre A1 y C1 o el enlace entre A2 y A3 o el enlace entre C1 y C2 o el enlace entre A3 y C2
