1. Adult Activity
Cyclamen mites are extremely small and almost invisible to the naked eye. Adults are usually found within flower buds, young folded leaves, and growing tips, where humidity is highest and they are protected from direct sunlight. Because of their hidden feeding sites and extremely small size adult activity is rarely noticed until damage appears.
2. Juvenile Stages on Leaves
Nymphs and larvae inhabit the same protected areas as adults. Infested leaves may appear slightly distorted or sticky under close inspection. Due to their minute size, these immature stages are often difficult to detect with a 10× hand lens. We recommend collecting leaf samples and examining them under a microscope for a more accurate identification.
3. Sap Feeding Damage
Cyclamen mites feed by piercing plant tissues and extracting nutrient-rich sap. This feeding disrupts normal growth and development. Symptoms vary by host plant but commonly include twisted, curled, or stunted leaves. Infested leaves may be brittle, deformed, and smaller than usual. In flowers, buds can shrivel, deform, or fail to open. Growth may be stunted entirely in severe infestations.
4. Host-Specific Symptoms
- Cyclamen: Flower buds are deformed, and leaf growth is stunted.
- Hedera: Mite attacks can cause bald spots along stems.
- Gerbera: Flowers and leaves discolor along the midrib, turning bronze.
- Strawberry: Leaves become wrinkled, short-stemmed, and may die; young fruits turn brown near the base.
Managing Cyclamen Mites
Prevention and monitoring are essential due to their hidden feeding habits:
-
Regular crop scouting: Inspect young leaves, buds, and growing tips for early signs of distortion or curling.
-
Sanitation: Remove heavily infested plants promptly to prevent local spread.
-
Environmental management: Reduce humidity in the canopy where possible, and avoid conditions that favor mite survival.
-
Cultural practices: Avoid overcrowding plants, prune infested areas, and maintain clean propagation materials.
By understanding the subtle signs of cyclamen mite activity and monitoring early, growers can protect crops and reduce losses. Prompt intervention and integrated management are key to maintaining healthy plants.
