Eupolybothrus fasciatus

Eupolybothrus fasciatus is a predatory centipede belonging to the class Chilopoda, order Lithobiomorpha, and family Lithobiidae. It is characterized by a flattened, reddish-brown body with distinct dark stripes across its segments.

Adult individuals typically grow to lengths of 20–30 mm. They possess powerful maxillipeds equipped with venom glands, which they use primarily to hunt soil-dwelling invertebrates, but occasionally they bite plant tissues.

Unlike millipedes, which are scavengers or herbivores, these centipedes are fast-moving hunters. Their body structure allows them to navigate through small soil crevices and under surface debris with great efficiency.

The life cycle involves multiple stages of growth, with individuals remaining sensitive to moisture levels throughout their development. They prefer humid, sheltered environments for survival.

Identification is easiest at night or after irrigation, when these centipedes emerge from their subterranean hiding spots to search for prey and moisture.

While primarily predatory, Eupolybothrus fasciatus can become a nuisance in greenhouse settings and nurseries. When prey is scarce, they may feed on soft, succulent plant parts.

They predominantly target the root systems and hypocotyls of young vegetable seedlings. Tomato and cucumber transplants are particularly susceptible to their feeding habits.

Damage typically appears as small pits or gouged tissue on the surface of roots. These wounds serve as entry points for pathogens, leading to secondary fungal or bacterial infections.

Seedlings may exhibit stunted growth, wilting, or yellowing leaves due to the compromise of their vascular structure, which prevents proper water and nutrient uptake.

High populations of this centipede can significantly reduce crop establishment rates by feeding on germinating seeds before they emerge from the soil.

These centipedes are most active during the spring and autumn when soil temperatures are moderate and moisture levels are high.

During the hot summer months, they tend to move deeper into the soil profile to avoid desiccation, becoming less visible but remaining present in the root zone.

In greenhouses where conditions are optimized for crop growth, they can remain active throughout the entire year, posing a constant threat to nursery stock.

The period following heavy rains or systematic irrigation is when their surface activity and feeding on plant tissues reach a peak.

Winter survival is achieved by retreating into deeper soil layers, beneath compost piles, or inside dense, moist organic matter that offers protection from frost.

One of the most reliable signs is the presence of small, irregular holes on the stems of young plants just below the soil surface.

Wilting plants that do not respond to water often indicate root damage, suggesting that the root system has been compromised by soil-dwelling pests.

Finding adult centipedes under boards, weed mats, or moisture-retaining mulch in proximity to the crop is a strong indicator of an existing population.

Poor germination or erratic stand density in a crop field may suggest that seeds were consumed or damaged by centipedes during the initial growth phase.

Observing rapid, darting movements of reddish-brown creatures during field cultivation or soil preparation is a sign of their widespread presence.

Cultural control is the most effective approach. Frequent soil cultivation disrupts the tunnels and habitat of centipedes, making the environment less hospitable.

Proper moisture management is essential. Avoiding overly saturated soil and minimizing standing water around the base of plants can reduce their attraction to the root zone.

Mechanical traps, such as moistened pieces of cardboard or burlap, placed overnight can be used to monitor and collect centipedes for manual removal.

Biological control using entomopathogenic nematodes has proven effective in suppressing soil pest populations without damaging the ecosystem.

In severe infestations, the application of registered granular insecticides into the soil before planting can provide a necessary level of protection for vulnerable young plants.
