Spirobolidae millipedes
The Spirobolidae family belongs to the class Diplopoda. These millipedes are typically detritivores in forest soils, but in agricultural settings, they can become significant pests by feeding on living plant tissues, especially when natural organic food sources are scarce.

Spirobolidae millipedes
These pests primarily target underground plant structures. They are known to feed on germinating seeds, young roots, potato tubers, carrots, and sugar beets. In greenhouse environments, they frequently destroy seedlings by severing the stems at the soil line, causing significant economic losses.
Their life cycle is highly dependent on environmental moisture and temperature. Spirobolidae deposit eggs in the soil, and the larvae develop through several molts. They are most active during moist, humid conditions, often retreating deeper into the soil during dry spells or extreme temperature fluctuations.
The damage caused by these millipedes is characterized by irregular holes and deep tunneling in roots and tubers. These wounds serve as entry points for secondary fungal and bacterial pathogens, which often result in soft rots, making the produce unmarketable and susceptible to rapid decay.
Effective management strategies rely on integrated pest control practices:
- Implementing crop rotation to disrupt the pests' life cycle.
- Removing debris and excessive organic matter from the soil surface.
- Improving soil drainage to create unfavorable conditions for these moisture-loving pests.
- Applying granular soil insecticides where local infestation thresholds are exceeded.
