DDT is similar in structure to the insecticide methoxychlor and the acaricide dicofol. It is highly hydrophobic and nearly insoluble in water but has good solubility in most organic solvents, fats and oils. DDT does not occur naturally and is synthesised by consecutive Friedel–Crafts reactions between chloral (CCl 3 CHO) and two equivalents ...
The pesticide manual provides much information on pesticides. [6] [7] Many of the insecticides in the list are not in use. The developer of a pesticide applies for a common name when they intend to sell it, but some nevertheless do not reach the market. Many insecticides have been banned or otherwise withdrawn from the market over the decades.
The two main groups of organochlorine insecticides are the DDT-type compounds and the chlorinated alicyclics. Their mechanism of action differs slightly. The DDT like compounds work on the peripheral nervous system. At the axon's sodium channel, they prevent gate closure after activation and membrane depolarization. Sodium ions leak through the ...
DDE and its parent, DDT, are reproductive toxicants for certain birds species, and major reasons for the decline of the bald eagle, [5] brown pelican [6] peregrine falcon, and osprey. [7] These compounds cause egg shell thinning in susceptible species, which leads to the birds' crushing their eggs instead of incubating them, due to the latter's ...
Dichlorodiphenyldichloroethane (DDD) is an organochlorine insecticide that is slightly irritating to the skin. [1] DDD is a metabolite of DDT. [2] DDD is colorless and crystalline; [3] it is closely related chemically and is similar in properties to DDT, but it is considered to be less toxic to animals than DDT. [4]
In 2016 insecticides were estimated to account for 18% of worldwide pesticide sales. [2] Worldwide sales of insecticides in 2018 were estimated as $ 18.4 billion, of which 25% were neonicotinoids, 17% were pyrethroids, 13% were diamides, and the rest were many other classes which sold for less than 10% each of the market.

Monsanto began manufacturing DDT in 1944, along with some 15 other companies. This insecticide was used to kill malaria-transmitting mosquitoes, but it was banned in the United States in 1972 due to its harmful environmental impacts. In 1977, Monsanto stopped producing PCBs; Congress banned PCB production two years later. [37] [38]
