ABSTRACT:
Novel substituted pyridylmethyl-cyanoiminoimidazolidines and pyridylmethyl-cyanoiminotetrahydropyrimidines of the formula ##STR1## in which R.sub.3 is hydrogen or C.sub.1 -C.sub.4 alkyl; A is a --(CH.sub.2).sub.2 -- or --(CH.sub.2).sub.3 -- radical; X is halogen; and n is an integer 0, 1, 2 or 3; and the salts of compounds of formula I. Also described is a process for the preparation of these compounds, the corresponding starting materials and intermediates, and the use of the novel compounds in pest control, especially for controlling insects and representatives of the order Ararina, particularly insect pests in rice crops.
