Rhinocricus nattereri

Rhinocricus nattereri belongs to the class Diplopoda, order Spirobolida, and family Rhinocricidae. These tropical millipedes, while often considered decomposers in natural ecosystems, can become significant pests in agriculture when their population density exceeds thresholds in areas with high soil moisture.

This species primarily attacks a variety of root crops, tubers, and seedlings. They are particularly problematic in humid tropical and subtropical farming systems where the soil environment is consistently damp, providing the necessary microclimate for their survival and reproduction.

The life cycle of this millipede consists of egg, larval, and adult stages. Development is relatively slow and highly dependent on temperature and soil organic matter availability. They spend almost their entire lifecycle underground, emerging occasionally or concentrating in the rhizosphere of target plants.

Damage occurs when the millipedes feed on roots, tubers, and seeds. By boring into plant tissues, they not only cause physical damage but also introduce various pathogens that lead to rot. This can cause widespread plant loss, poor establishment of seedlings, and reduced yields at harvest.

Effective management strategies against this pest include:

• Managing soil moisture levels through proper irrigation and improved field drainage.
• Application of soil-applied insecticides specifically targeted at subterranean millipedes.
• Using bait stations with fermented plant material to attract and destroy populations.
• Maintaining field hygiene by removing organic debris that serves as breeding sites.
