Malathion is a pesticide that is widely used in agriculture, residential landscaping, public recreation areas, and in public health pest control programs such as mosquito eradication.[5] In the US, it is the most commonly used organophosphate insecticide. However Malathion is extremely useful in mosquito control.

ENDOSULFAN
Endosulfan has been used in agriculture around the world to control insect pests, including whiteflies, aphids, leafhoppers, Colorado potato beetles and cabbage worms. Due to its unique mode of action, it is useful in resistance management; however, as it is not specific, it can negatively impact populations of beneficial insects.[11] It is, however, considered to be moderately toxic to honey bees,[12] and it is less toxic to bees than organophosphate insecticides.
DDT
DDT is similar in structure to the insecticide methoxychlor and the acaricide dicofol. Being highly hydrophobic, it is nearly insoluble in water but has good solubility in most organic solvents, fats and oils. DDT does not occur naturally, but is produced by the reaction of chloral (CCl
3CHO) with chlorobenzene (C
6H
5Cl) in the presence of sulfuric acid as a catalyst. Trade names that DDT has been marketed under include Anofex, Cezarex, Chlorophenothane, Clofenotane, Dicophane, Dinocide, Gesarol, Guesapon, Guesarol, Gyron, Ixodex, Neocid, Neocidol and Zerdane.
