Peridontopyge schoutedeni

Peridontopyge schoutedeni is a species of millipede within the family Odontopygidae. While many millipedes are harmless decomposers, this specific species is recognized as an agricultural pest in various African regions, where it impacts the productivity of essential food crops.

The biology of this species is tied closely to soil moisture levels and organic matter availability. These millipedes thrive in environments where decaying plant material is abundant, but as their population density increases, they frequently exhibit opportunistic feeding behavior on living plant tissues, particularly roots and germinating seeds.

Primary agricultural damage is observed in crops such as groundnuts (peanuts) and various tuber crops. By feeding on the cotyledons and tender stems, Peridontopyge schoutedeni causes mechanical damage that facilitates the entry of soil-borne pathogens, leading to seed rot and plant stand loss shortly after germination.

The life cycle involves egg-laying in the soil, followed by multiple larval instars. The developmental speed is highly correlated with rainfall patterns; thus, the onset of the rainy season often marks a period of increased activity and potential threat to newly planted agricultural fields, requiring farmers to stay alert.

Management of this pest requires an integrated approach to reduce population impact:

• Implementing crop rotation to disrupt the millipede life cycle.
• Mechanical soil cultivation to disturb nesting sites and expose larvae.
• Seed dressing with systemic insecticides to provide a protective barrier during the seedling stage.
• Maintaining field hygiene by removing excessive plant debris that serves as a food reservoir.
