What indicates garden symphylans’ presence in a field?

• A. Stunted growth in crop plants
• B. Circular areas with little crop or weed growth
• C. The presence of excessive moisture
• D. Sporadic pest activity

Answer: (B)

The presence of garden symphylans in a field is indicated by circular areas with little crop or weed growth. This is because garden symphylans, which are small, wriggling soil-dwelling arthropods, feed on the roots of various plants, causing damage that often results in localized patches of poor growth. Over time, this root feeding can lead to the formation of distinct areas in the soil where vegetation fails to thrive, creating circular patches with little to no crop or weed growth. Other indicators, such as stunted growth in crop plants, may suggest various problems including nutrient deficiencies or other pest issues, but they are not specific to garden symphylans alone. Excessive moisture may facilitate conditions for other pests or diseases but does not specifically point to symphylans. Likewise, sporadic pest activity could refer to many different types of pests, making it an unreliable indicator for detecting garden symphylans specifically.
