John Edward Casida (December 22, 1929 – June 30, 2018) was an American entomologist, toxicologist and professor at the University of California, Berkeley.
Additional areas of study include research on the synthesis, metabolism, toxicokinetics and mechanisms of toxicity of the organophosphates, pyrethroids and neonicotinoids.
In addition, he is described as being a "Highly Cited" researcher by ISI Web of Knowledge, and currently has in excess of 850 scientific publications.
He synthesized compounds more active and less persistent than insecticides then used in agricultural practice and his contributions have provided a rational basis for the evaluation of the risks and benefits of pesticides and toxicants.
[7] In 1993, he was awarded the Wolf Prize in Agriculture "for his pioneering studies on the mode of action of insecticides, design of safer pesticides and contributions to the understanding of nerve and muscle function in insects".
