Abstract: The invention relates to a method of controlling insects in the family Nitidulidae using the compound 4,5-di -hydro-6-methyl-4-(3-pyridylmethyleneamino)-1,2,4-triazin-3(2H)-one and also encompasses the use of compositions comprising 4,5-dihydro-6-methyl-4-(3-pyridylmethyleneamino)-1,2,4-triazin-3(2H)-one for controlling Nitidulidae, in particular pollen beetles as well as the preparation of said compound and/or compositions for use in controlling Nitidulidae. In particular, the invention relates to the use of 4,5-dihydro-6-methyl-4-(3-pyridylmethyleneamino)-1,2,4-triazin-3(2H)-one and/or compositions comprising this compound in controlling such insects in crops of useful plants, in particular flowering crops and/or flowering ornamental plants.
