Etymology
Coumaphos combines couma-, from coumarin (a plant chemical with a sweet smell), and -phos, from a word for 'phosphorus' used in many insect poisons. So, coumaphos is an insecticide named for its coumarin-like part and its phosphorus part, which helps explain why it is used to control parasites on animals.
