Soil centipede

The species Henia bicarinata belongs to the family Linotaeniidae within the order Geophilomorpha. These elongated, multi-legged organisms are typically subterranean dwellers. While primarily predatory in nature, under specific ecological conditions or high population densities, they can cause damage to the root systems and seedlings of various cultivated plants in agricultural settings.

The biology of Henia bicarinata is highly dependent on environmental moisture and the availability of organic matter. They thrive in damp, undisturbed soils, where they move through existing cracks and tunnels. Reproduction occurs in protected soil micro-habitats, and the life cycle includes multiple molting stages, allowing them to rapidly colonize suitable areas if conditions remain stable.

Damage to plants occurs when these centipedes feed on the soft tissues of roots, tubers, and the hypocotyls of young sprouts. The mechanical injury inflicted by their mouthparts can lead to the wilting of young plants and significant gaps in crop stands. Furthermore, these wounds provide entry points for soil-borne pathogens, leading to root rot and systemic infections that further devastate the yield.

Crops such as potatoes, carrots, and various vegetable seedlings are most vulnerable. The presence of the pest is often detected too late when plants start to show chlorosis or stunted growth. Greenhouse environments, with their constant humidity and lack of seasonal temperature fluctuations, are particularly prone to outbreaks of Henia bicarinata that require immediate attention.

Effective management requires an integrated approach. Cultural practices such as maintaining good soil drainage and avoiding excessive surface organic debris are critical in reducing the population. Crop rotation and timely soil cultivation disrupt the life cycle of the centipedes by exposing them to predators and unfavorable environmental conditions. Where infestation is severe, specific soil-applied insecticides may be necessary.

• Regular soil tilling to disturb nesting sites.
• Improvement of drainage systems to prevent waterlogging.
• Removal of plant debris that harbors moisture.
• Use of soil-applied biopesticides where applicable.
• Monitoring of young seedlings for signs of root feeding.
