Solpugids

Affected crops: These arachnids do not consume plant material as their main food source; however, they can inadvertently damage various crops such as vegetables, melons, and young seedlings. Their habit of digging burrows and hunting in soil layers makes them a concern for farmers operating in desert or semi-arid climates where these creatures are abundant.

Biology and life cycle: The life cycle of solpugids involves an egg stage, several larval stages, and multiple nymphal instars before reaching adulthood. They are extremely fast-moving, nocturnal hunters that rely on tactile and vibration cues to find prey. During the day, they remain sheltered in burrows or under organic debris, making them difficult to detect during standard crop scouting.

Damage character and economic importance: The damage is primarily mechanical. Their powerful chelicerae can sever plant stems, injure root systems during excavation, or cause lesions that become entry points for secondary pathogens like fungi and bacteria. High populations can cause patchy crop emergence and physical damage to young, tender plants, leading to yield losses in localized areas.

Control measures: Management of solpugids is primarily focused on habitat modification rather than chemical eradication, as they act as natural predators of other pests. Recommended strategies include:

• Elimination of shelter sites by clearing field edges and removing excessive debris.
• Deep tillage or plowing to disrupt and destroy their underground burrows.
• Maintaining optimal irrigation schedules to prevent overly dry conditions favored by the species.
• Implementation of physical barriers for high-value crops in greenhouse settings.
