The present invention relates to pesticidal mixtures comprising as active compounds 1) at least one isoaxazoline compound I of the formula (I) ##STR00001## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and A are defined in the description; and 2) at least one active compound II selected from a group A comprising acteylcholine esterase inhibitors, GABA-gated chloride channel antagonists, sodium channel modulators, nicotinic acteylcholine receptor agonists/antagonists, chloride channel activators, juvenile hormone mimics, compounds affecting the oxidative phosphorylation, inhibitors of the chitin biosynthesis, moulting disruptors, inhibitors of the MET, voltage-dependent sodium channel blockers, inhibitors of the lipid synthesis and other compounds as defined in the description, in synergistically effective amounts. The invention relates further to methods and use of these mixtures for combating insects, arachnids or nematodes in and on plants, and for protecting such plants being infested with pests, especially also for protecting plant propagation material as like seeds.

The present invention relates to novel active compound combinations comprising at least one known compound of the formula (I) ##STR00001##
in which X, R.sub.1 to R.sub.4, A, n, Y, and m are as defined in the description, and at least one further known active compound from the class of the pyrethroids, which combinations are highly suitable for controlling animal pests such as insects and unwanted acarids.
