The invention relates to novel tetrazine derivatives of the formula (I), wherein X means fluorine, chlorine or bromine; and Y stands for hydrogen or fluorine, as well as to a process for the preparation thereof. Furthermore, the invention relates to compositions containing the above compounds as well as to a process for the preparation thereof. The compounds and compositions according to the invention have acaricidal, larvicidal and ovicidal effects. The advantage of the active compounds of the invention consists in that their effect is translaminar; in addition, they also show a systemic effect. They are particularly useful for combatting mites belonging to the Tetranychidae family of pests.
