Permethrin is a medication and an insecticide. [4][5] As a medication, it is used to treat scabies and lice. [6] It is applied to the skin as a cream or lotion. [4] As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them. [5][7] Side effects include rash and irritation at the area of use. [6]
The acute toxicity of pesticides on bees, which could be by contact or ingestion, is usually quantified by LD 50. Acute toxicity of pesticides causes a range of effects on bees, which can include agitation, vomiting, wing paralysis, arching of the abdomen similar to sting reflex, and uncoordinated movement. Acute toxicity may depend on the mode ...
A pyrethroid is an organic compound similar to the natural pyrethrins, which are produced by the flowers of pyrethrums (Chrysanthemum cinerariaefolium and C. coccineum). Pyrethroids are used as commercial and household insecticides. [1] In household concentrations pyrethroids are generally harmless to humans. [1]

Cypermethrin (CP) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces.
Pyrethrin. The pyrethrins are a class of organic compounds normally derived from Chrysanthemum cinerariifolium that have potent insecticidal activity by targeting the nervous systems of insects. Pyrethrin naturally occurs in chrysanthemum flowers and is often considered an organic insecticide when it is not combined with piperonyl butoxide or ...
Effects were also observed in the liver (rats, mice, and dogs), heart (dogs), and thyroid gland (rats). Some effects were also seen in the kidney (mice and rats). However, neurotoxicity was the most sensitive endpoint in the toxicology database, and other effects were generally seen in the presence of neurotoxicity and/or at higher doses.
Allethrin II (R = −COOCH 3) The allethrins are a group of related synthetic compounds used in insecticides. They are classified as pyrethroids, i.e. synthetic versions of pyrethrin, a chemical with insecticidal properties found naturally in Chrysanthemum flowers. They were first synthesized in the United States by Milton S. Schechter in 1949.
