In the US, it is the most commonly used organophosphate insecticide. [6] A malathion mixture with corn syrup was used in the 1980s in Australia and California to combat the Mediterranean fruit fly. [7] In Canada and the US starting in the early 2000s, malathion was sprayed in many cities to combat west Nile virus. [8]
Variants with P=S double bonds were developed as insecticides because of their reduced mammalian toxicity. The phosphorothioate P=S bond is converted to the toxic P=O bond in the target insect. Similar oxidative conversion in mammals is slower, conferring lower toxicity in mammals.
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 Many insecticides have been banned or otherwise withdrawn from the market over the decades.

[2] For scabies either permethrin or malathion is typically preferred. [3] It is applied to the skin as a lotion. [2] Typically two to three applications are needed. [2]
Sucking insects use feeding tubes to feed from phloem (e.g. aphids, leafhoppers, scales and whiteflies), or to suck cell contents (e.g. thrips and mites). An insecticide is more effective if it is in the compartment the insect feeds from. The physicochemical properties of the insecticide determine how it is distributed throughout the plant. [11 ...

At one time, cotton growers applied more than 41 percent of all insecticides in agricultural use; they regularly sprayed their cotton as many as 15 times a season. In contrast, under this program, only two applications are made by the third year, and this number may be reduced to nearly zero when the nationwide program is completed.
