Atopomelid mites

Affected crops. These mites often target ornamental plants, greenhouse vegetables, and exotic species grown in indoor environments. They thrive where organic debris and micro-climatic humidity levels are high. Greenhouse environments provide a protected niche that facilitates their survival and reproduction throughout the year, especially on plants with complex leaf structures.

Biology and life cycle. The life cycle consists of egg, larva, nymphal stages, and adult. They are highly responsive to environmental triggers, with optimal development occurring in warm and humid conditions. Their hidden behavior, often residing in leaf axils or under debris, allows them to establish significant populations before they are visually detected by agronomists during standard field inspections.

Nature of damage and harmfulness. The feeding activity involves piercing plant tissues to extract sap, leading to chlorosis, stunted growth, and physical deformation of new leaves. This injury often serves as a primary vector for secondary plant diseases. Heavy infestations can lead to significant biomass loss and reduced photosynthetic efficiency, ultimately impacting the overall market value of the crop.

Protection measures. Effective control requires an integrated pest management (IPM) approach to mitigate risks:

• Strict sanitation protocols for greenhouse tools and equipment.
• Implementation of humidity control systems to discourage mite proliferation.
• Targeted application of acaricides during the early stages of infestation.
• Biological control using predatory mites known to suppress Sarcoptiformes.
• Regular inspection of imported plant material to prevent the introduction of new colonies.
