• the compounds defined by the general formula .I are capable of increasing the activity of insecticidal and/or acaricidal compounds many-fold (synergism). Surprisingly, it has also been found that when using compounds of the formula I, insects or representatives of the order Acarina, which are resistant to carbamates or phosphoric acid esters, can be rendered completely sensitive to these latter compounds.
• Suitable insecticidally or acaricidally active substances are, for example, the following compounds: 7
