Methoxyfenozide

Type: Insecticide / Insect Growth Regualtor

Mode of Action: 

• Group 18: Ecdysone receptor agonists

Common Product Names: Intrepid & Inspirato

What is it?

Methoxyfenozide belongs to the diacylhydrazine class of insecticides. It is particularly effective against lepidopteran larvae (caterpillars) and is used extensively in the protection of fruits, vegetables, and other crops. Methoxyfenozide is noted for its selective toxicity, meaning it targets specific pests while being relatively safe for non-target organisms, including beneficial insects, humans, and wildlife.

How does it work?

Methoxyfenozide works by mimicking the molting hormone of insects. When ingested or contacted by the target larvae, it triggers premature molting. Since the insect is not prepared to molt, this process disrupts its development, leading to death before it reaches the adult stage. This ensures that the population of the pest is controlled effectively, as the insects are unable to reproduce.

Benefits

• Reduced Resistance: Due to its unique mode of action, it helps in managing resistance development in pest populations.
• Long Residual Activity: Provides extended protection, reducing the need for frequent applications.
• Low Mammalian Toxicity: Presents a lower risk to human health compared to many other insecticides.
