Solpuga brunnipes

Solpuga brunnipes is an arachnid belonging to the order Solifugae (commonly known as camel spiders or wind scorpions). While primarily predatory, consuming various insects and small invertebrates, they are occasionally documented in agricultural settings, where they may interact with crops in arid and semi-arid environments.

The biological cycle of Solpuga brunnipes consists of egg, larval, and several nymphal stages before reaching adulthood. These arachnids are highly sensitive to soil moisture and temperature, preferring loose, sandy substrates where they can easily burrow to escape the heat of the day. They are largely nocturnal, which defines their interaction pattern with crops.

In terms of damage, they are generally not considered primary agricultural pests. However, they can cause mechanical injury to young seedlings. By digging their burrows near crop bases or cutting through stems to reach moisture, they can inadvertently weaken the plants, leading to wilting or stunted growth in early growth stages.

The pest status of these organisms is localized. Damage occurs most frequently during prolonged droughts when the natural food sources of the solifugids are scarce. Consequently, they may investigate crop stems for hydration, causing cosmetic or structural damage that exposes the plant to pathogens.

Management strategies focus on cultural practices rather than chemical control. Regular cultivation of the soil effectively disrupts the burrowing sites of Solpuga brunnipes and reduces their population density. Maintaining good field hygiene by removing crop debris and stone piles significantly lowers the suitability of the habitat for these arachnids.

• Deep soil tillage and harrowing
• Removal of weeds and crop residues
• Maintenance of adequate field moisture
