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 .

Pyrethroids are manufactured chemicals that are very similar in structure to the pyrethrins, but are often more toxic to insects, as well as to mammals, and last longer in the environment than pyrethrins. More than 1,000 synthetic pyrethroids have been developed, but less than a dozen of them are currently used in the United States.

Oct 31, 2018 · Pyrethroid insecticides are a special chemical class of active ingredients found in many of the modern insecticides found on store shelves and used by pest management professionals. The name pyrethroid means “pyrethrum-like” and refers to …

Pyrethroids are pesticides commonly used in crop protection; in the forestry, wood, and textile industries; as well as in medicine and veterinary medicine to treat parasitic crustacean infestations. They have been found to be relatively safe for humans and animals.

By consolidating current knowledge and research findings, this review provides a comprehensive understanding of the properties and applications of pyrethrins and pyrethroids, highlighting their benefits and risks, and the importance of responsible and sustainable use in various areas.

Aug 11, 2024 · Pyrethrin and pyrethroid compounds are valued for their potent insecticidal properties while maintaining a high safety profile in humans. Pyrethrins are naturally occurring chemicals, while pyrethroids are artificial and more likely to cause toxicity.

May 1, 2023 · Pyrethroid pesticides are neurotoxins that specifically target the voltage-gated sodium channel's receptor site (Kadala et al., al.,2014; Zhorov and Dong, 2017; Valmorbida et al., al.,2022). They kill insects by binding to sodium channels, which results in excitatory paralysis.

Pyrethrins and pyrethroids are insecticides that are applied to crops, garden plants, pets, and also directly to humans. High levels of pyrethrins or pyrethroids can cause dizziness, headache, nausea, muscle twitching, reduced energy, changes in …

Apr 9, 2025 · Pyrethroid molecules that lack the alpha-cyano group are referred to as type I, or first-generation. Pyrethroids with the alpha-cyano group are referred to as type II, or second-generation—this CN group enhances the insecticidal activity and molecular stability and results in clinical differences of exposures between groups (Matsuo 2019 ...

Pyrethroid compounds are widely used as insecticides. These compounds not only have a versatile application, but also have favourable toxicological profiles with high selectivity and toxicity to insects and low toxicity to humans.
