.alpha.-unsaturated amines, their production and use
.alpha.-Unsaturated amines of the formula: ##STR1## wherein X.sup.1 and X.sup.2 are such that one is an electron-attracting group with the other being a hydrogen atom or an electron-attracting group; R.sup.1 is a group attached through a nitrogen atom; R.sup.2 is a hydrogen atom or a group attached through a carbon, nitrogen or oxygen atom; n is an integer equal to 0, 1 or 2; A is a heterocyclic group or a cyclic hydrocarbon group, and salts thereof and their agrochemical use as insecticidal and/or miticidal agents are described.

Insecticidal nitro-substituted heterocyclic compounds of the formula ##STR1## wherein R.sup.1 represents hydrogen, cyano or C.sub.1-4 alkyl, m represents 0 or 1, n represents 0 or 1, R.sup.2 represents hydrogen or C.sub.1-4 alkyl, R.sup.3 represents hydrogen, C.sub.1-6 alkyl optionally substituted substituted by cyano, halogen or C.sub.1-4 alkoxy, C.sub.3-4 alkenyl, C.sub.3-4 alkynyl, optionally substituted phenyl, optionally substituted benzyl or optionally substituted heterocyclic-methyl, T represents an optionally substituted two- or three-membered divalent or trivalent chain comprising hetero atoms and/or carbon atom, and A represents optionally substituted phenyl or an optionally substituted five- or six-membered heterocyclic radical comprising at least one hetero atom selected from the group consisting of N, O and S.
There is provided a pest control composition containing a compound represented by the formula, ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are the same or different and independently mean a hydrogen atom, a hydrocarbon group which may be substituted or a heterocyclic group which may be substituted and X means an electron attracting group or a salt thereof. The compounds are of minimal toxicity to man, domestic animals and fish and selectively display remarkable control effect on pests.
