1-arylpyrazoles and their use as pesticide

A method of controlling parasites in or on an animal comprising orally administering to the animal a parasitically effective, substantially non-emetic 1-arylpyrazole.

Control of arthropods in animals

A method of systemically controlling endoparasites and ectoparasites of warm-blooded animals by orally or percutaneously administering to the animal a parasiticidally effective amount of an acyl urea compound.

Use of acyl urea compounds for controlling endoparasites and
