<; p >; This Invention relates to novel compounds of the formula I and azolobenzazina to N - oxides, estereois u00d3meros,Taut u00d3meros acceptable salts in Agriculture and Veterinary or those where C is c or C is c or CH CH N C N, C (R), (R), or n, s or C (R4, R5); and is n, o, S, N (r6), C (R7 R8, or (c)R?) Is n; A4 or A5 is C (R); n or C (R); A6 is n or C (R), where one or two non adjacent links in the five Member Ring formed by C, C, a, a and a are double Bonds,While the others are simple links provided the link between a u00a0 and or the link between a and C or the link between a u00a0 and a u00a0 or the link between C and c u00a0 or the link between a and C is a double Bond,Also provided that at least one of a, and a is n, N (R) or N (r6), where r, r, r, r, r, R4, R5, R6, R7, R8 and R? Are as defined in the claims.The compounds of formula (i), as well as the N - Oxides and salts, estereois u00d3meros, taut u00d3meros acceptable in Agriculture and Veterinary Medicine,They are useful to combat and control pests of Invertebrates, particularly Arthropods pests and nematodes.The Invention also relates to a method for Control of Invertebrate pests by the use of these compounds.A u00a0 Plant propagation materials and an agricultural and Veterinary composition comprising these compounds. <; / p >;<;p>;LA PRESENTE INVENCIÓ;N SE REFIERE A COMPUESTOS DE AZOLOBENZAZINA NOVEDOSOS DE LA FORMULA I Y A LOS N-Ó;XIDOS, ESTEREOISÓ;MEROS, TAUTÓ;MEROS Y LAS SALES ACEPTABLES EN LA AGRICULTURA O VETERINARIA DE AQUELLOS, EN DONDE C ¹; 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,R?); 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; , A²;, A²; Y A³; SON ENLACES DOBLES, MIENTRAS QUE LOS OTROS SON ENLACES SIMPLES SIEMPRE QUE EL ENLACE ENTRE A&s
