Diflubenzuron

Diflubenzuron is a benzoylurea-based insecticide that is used in integrated pest management programs. It is a chitin synthesis inhibitor, which means it prevents the formation of chitin, a key component of an insect's exoskeleton. This makes it particularly effective against a variety of insect pests, including mosquitoes, gypsy moths, and forest tent caterpillars.

History

Diflubenzuron was first registered for use in the United States in 1976. It was developed by Philips-Duphar, a Dutch company that was later acquired by Solvay. The insecticide is now produced by several manufacturers worldwide.

Mode of Action

Diflubenzuron works by inhibiting the synthesis of chitin in the insect's body. Chitin is a crucial component of the insect's exoskeleton, and without it, the insect cannot grow or reproduce. This makes diflubenzuron a highly effective tool in the control of insect populations.

Uses

Diflubenzuron is used in a variety of settings, including agriculture, forestry, and public health. In agriculture, it is used to control pests such as the codling moth and the oriental fruit moth. In forestry, it is used to control pests such as the gypsy moth and the forest tent caterpillar. In public health, it is used to control mosquito populations.

Safety and Environmental Impact

Diflubenzuron is considered to be of low toxicity to humans and other mammals. However, it can be harmful to aquatic organisms, particularly those that rely on chitin for their exoskeletons, such as crustaceans and insects. Therefore, care must be taken to prevent diflubenzuron from entering water bodies.
