General Pharmacology: The Vascular System, 1978
Natural pyrethrins, also called "pyrethrum" or "'pyrethrum extract", have long been known as insecticides. They are extracted from the flowers of Chrysanthemum cinerariaefolium Vis which contain six insecticidally active components, of which pyrethrin I and pyrethrin II are the most active (Head 1973, Elliott & Janes, 1973).

Section 10. Pyrethroid resistance: resistance breaking pyrethroids
Bulletin of entomological research supplement series, 1993SummaryThe structural requirements for designing a resistance breaking pyrethroid to overcome oxidative metabolic pyrethroid resistance in Helicoverpa armigera were studied. A range of pyrethroid structures were tested on a well defined pure breeding pyrethroid resistant strain of H.

The first pyrethroid pesticide, allethrin, was identified in 1949. Allethrin and other pyrethroids with a basic cyclopropane carboxylic ester structure are type I pyrethroids. The insecticidal activity of these synthetic pyrethroids was enhanced further by the addition of a cyano group to give alpha-cyano (type II) pyrethroids, such as cypermethrin ...

A system containing a polyarylphenolethoxylate as the nonionic surfactant, and a calcium dodecylbenzenesulfonate in alcohol as the anionic surfactant and co-surfactant respectively, was used to study microemulsions of Permethrin and Cypermethrin (common insecticides of the important Pyrethroids class).
