Why Tebufenozide Is a Game-Changer in Lepidopteran Pest Control

Introduction

Tebufenozide is a highly targeted insect growth regulator (IGR) used primarily to control larvae of Lepidoptera (moths and butterflies). As an ecdysone agonist, it mimics the molting hormone in insects, forcing premature molting and eventual death of the larvae. Due to its high selectivity and low toxicity to beneficial insects, Tebufenozide is widely used in integrated pest management (IPM) programs.

Product Information

• Name: Tebufenozide

• Chemical Name: N-tert-Butyl-N′-(4-ethylbenzoyl)-3,5-dimethylbenzohydrazide

• CAS Number: 112410-23-8

• Formulations: SC (suspension concentrate), EC (emulsifiable concentrate)

• Appearance: Pale yellow to amber liquid

Key Features

• Highly selective for Lepidoptera larvae

• Minimal impact on beneficial insects and pollinators

• Systemic-like action through ingestion

• Long residual activity on treated surfaces

• ♻️ Safe for use in IPM programs and organic transitions

Applications

Tebufenozide functions as a molt-accelerating compound, specifically mimicking 20-hydroxyecdysone, the natural molting hormone in insects. This triggers an abnormal and premature molt, causing the larvae to stop feeding and die within a few days.

Advantages

• ✅ High specificity = less harm to non-target species

• Environmentally safe and biodegradable

• Resistance management compatible

• Safe for bees, parasitoids, and predators

• Suitable for use in greenhouses and open fields

Limitations

• Only effective against larval stages, not eggs or adults

• Requires ingestion by pest for maximum efficacy

• Timing is critical: must be applied early in infestation

FAQs

Q: Is Tebufenozide safe for use during flowering periods?
A: Yes, due to its low toxicity to pollinators, it can be used around flowering crops if needed.

Q: How often should it be applied?
A: Typically every 7–14 days depending on pest pressure and environmental conditions.

Q: Can it be used in rotation with other insecticides?
A: Absolutely. It’s highly recommended for resistance management.

Conclusion

Tebufenozide stands out as a precise and environmentally conscious solution for managing lepidopteran pests. Its targeted mode of action, low environmental impact, and compatibility with beneficial insects make it an ideal choice for sustainable agriculture. When used correctly, it helps growers protect their crops without compromising ecological health.
