The present invention pertains to new substituted nitrogen heterocycles of general formula (I) ##STR1## in which R.sup.1 and R.sup.2 independently of each other, stand for hydrogen or alkyl,

Arylor hetaryl substituted nitrogen heterocycles and their use as

Insecticidal substituted diazacyclohexanes of the formula ##STR1## in which R.sup.1 is a heterocyclic radical,

Substituted aza(cyclo)alkanes

Insecticidally active substituted aza(cyclo)alkanes of the formula (I) ##STR1## in which R.sup.1 represents a five- or six-membered heterocyclic grouping which contains 1, 2, 3 or 4 nitrogen atoms and/or one or two oxygen atoms or sulphur atoms as the heteroatom ring members--the number of heteroatoms being 1, 2, 3 or 4--and which is optionally substituted

Pesticidal substituted pyridazinones of the formula ##STR1## in which R.sup.1 represents alkyl, halogenolkyl, alkoxyalkyl, alkylthioalkyl, (di)alkylaminoalkyl, alkenyl or halogenoalkenyl, or represents in each case optionally substituted cycloalkyl, cycloalkylalkyl, aryl or aralkyl,

Pesticidal chromen-6-yl-methyl-oxy-and-thiapyrizinones
