Lepimectin, developed by Japan’s Mitsui Chemicals, Inc. in 1997, is a novel 16-membered macrolide bio-insecticide derived from the structural modification of the renowned biopesticide milbemycin. Comprising Lepimectin A3 and Lepimectin A4, the compound was registered in Japan in 2006 and launched in 2010 under the trade name Aniki. It is primarily used to control Lepidoptera and Homoptera pests in vegetables and fruits such as cabbage, tomato, citrus, strawberry, and grapes. Its efficacy and fast-acting properties, especially against Lepidopteran pests, make it one of the most promising broad-spectrum and non-cross-resistant bio-insecticides available.

- CAS Numbers: 863549-51-3, 171249-10-8 (methyl), 171249-05-1 (ethyl)
Application and Insecticidal Spectrum
Lepimectin is widely applied in field crops such as Chinese cabbage, radish, tomato, eggplant, lettuce, broccoli, onions, tea, and citrus. It targets a variety of pests including:
- Plutella xylostella (diamondback moth)
- Spodoptera litura (armyworm)
- Helicoverpa armigera (cotton bollworm)
- Whiteflies, leafminers, leafrollers, and other Lepidoptera and Homoptera species
The insecticide is particularly effective against pests that are rapidly developing resistance to other compounds. Its mechanism of action involves activation of glutamate-gated chloride channels, causing paralysis and death in target pests.
Formulations and Usage
- Common formulations: 1% EC, 5% EC, 1% SC
- Application: Recommended for rotational use with avermectin-based insecticides to delay resistance development.
Market and Export Outlook
Since its debut in Japan in 2010, Lepimectin has gained traction in several Asian markets due to its broad-spectrum activity, low toxicity, and environmental safety. It is currently registered in Japan and South Korea and holds promise for wider international registration and adoption. Exporters are increasingly targeting markets in China, Southeast Asia, and Latin America, where sustainable agricultural inputs are in high demand.
Conclusion
Lepimectin represents a cutting-edge advancement in bio-insecticide technology. Developed by Mitsui Chemicals, its versatility in pest control, low environmental impact, and compatibility with resistance management strategies mark it as a standout option in integrated pest management programs worldwide.
