Immature stages cannot molt properly and die, which interrupts their lifecycle. Development inhibitors: refer to active ingredients that do not directly kill the parasites but interfere with their development.doramectin, moxidectin, selamectin) are used only against veterinary parasites. ![]() ![]() A few are also used in agriculture and hygiene. Most of them are semi-synthetic derivatives of natural fermentation products. ![]() They all act systemically, but can also act by contact and orally. Endectocides: refer to active ingredients of a specific chemical class, the macrocyclic lactones, which are effective against numerous external and internal parasites of livestock and pets.Many such active ingredients are also used in agriculture and in public and domestic hygiene. This is the largest group and includes organochlorines, organophosphates, carbamates, amidines, synthetic pyrethroids, neonicotinoids, phenylpyrazoles, etc. Classical ectoparasiticides: refer to synthetic organic active ingredients that kill parasites mainly by contact and are used in dips, sprays, pour-ons, spot-ons, etc.The most common ones are:ĭevelopmental stage affected by the active ingredient:Ī single active ingredients can be adulticide and larvicide, or only larvicide, or only adulticide, etc.Ī single active ingredient can be only insecticide, or only tickicice, or both, etc.Īn unofficial but pragmatic classification very much used in the Animal Health industry is to distinguish between four major groups: Classifications of ectoparasiticides (of insecticides in general)Įctoparasiticides can be classified according to various criteria. Thanks God, only a few active ingredients have been privileged with two or more names.Ĭlick here to learn more about general features of parasiticides such as spectrum of activity, mechanism of action, efficacy, residual effect, etc. Or both names may be used in the same country for veterinary use, etc. To keep it complicated, not all countries follow this distinction. diazinon (agricultural use) = dimpylate (veterinary use) or trichlorfon (agricultural use) = metrifonate (veterinary use). However, there are numerous exceptions.Ī remarkable practice is to use two different names for exactly the same active ingredient, one for its use in agricultural products, the other one for its use in veterinary products, e.g. injectables, drenches, tablets, etc.) that contain active ingredients not widely used in agriculture or hygiene tend to be considered as veterinary medicines. Whereas parasiticides for internal use (e.g. dipping, spraying, pour-ons, spot-ons, etc.) that contain active ingredients also used in agriculture or hygiene are considered as pesticides. As a general rule, parasiticides for external use (e.g. In fact, the terms "pesticide" and "veterinary medicine" are not clearly defined. Most ectoparasiticides for livestock, horses and pets are considered as pesticides, a few ones are considered as veterinary medicines. There are also parasiticides that are effective against both ecto and endoparasites and are called endectocides (e.g. This is in contrast with the endoparasiticides used against internal parasites known as endoparasites. They are also called ectoparasiticides because external parasites are also known as ectoparasites.
