Pyrethrins are classified as which type of parasiticide?

Anthelmintic
Insecticide
Antiviral
Antifungal

The correct answer is: Insecticide

Pyrethrins are classified as an insecticide because they are natural compounds derived from the flowers of certain chrysanthemum species. These compounds are highly effective against a wide range of insects by disrupting their nervous systems, leading to paralysis and death when exposed to the chemical. Pyrethrins are commonly used in various formulations for pest control in both agricultural and residential settings. The other classifications do not apply to pyrethrins. Anthelmintics are specifically used to treat worm infestations and would not affect insects. Antivirals target viruses and are irrelevant to insecticidal activity. Antifungals are aimed at treating fungal infections and also do not play a role in managing insect populations. Thus, the classification of pyrethrins as an insecticide is accurate based on their mechanism of action and intended use.
