Benzoylureas

Structural formula of diflubenzuron

The benzoylureas are a group of insecticides that act as chitin inhibitors . They inhibit chitin biosynthesis so that the pests can no longer form new cuticles and die with the next regular molt . The time delay limits their possible uses.

In adults , benzoylureas only reduce the mechanical stability of the cuticle. In contrast to phosphoric acid esters and carbamates , they are not neurotoxic.

Benzoylureas are primarily effective against lepidoptera . They include:

• Chlorfluazuron
• Diflubenzuron
• Flucycloxuron
• Flufenoxuron
• Hexaflumuron
• Lufenuron
• Novaluron
• Noviflumuron
• Teflubenzuron
• Triflumuron
