Methods of controlling insects

摘要

The invention relates to a method of controlling insects in the order Coleoptera, in particular insects in the family Nitidulidae, using the compound 1-acetyl-1,2,3,4-tetrahydro-3-[(3-pyridylmethyl)amino]-6-[1,2,2,2-tetrafluoro-1-(trifluoromethyl)ethyl] quinazolin-2-one in free form or in agrochemically acceptable salt form. The invention also encompasses the use of compositions comprising compounds of formula I for controlling Colpeteran insects, more specifically insects in the family Nitidulidae and in particular pollen beetles (insects of the genus Meligethes ), as well as the preparation of such compounds and compositions for use in controlling Coleoptera. In particular, the invention relates to the use of compounds of formula I and/or compositions comprising compounds of formula I in controlling such insects in crops of useful plants, in particular flowering crops and/or flowering ornamental plants.
