Indian mango mite

The Acaphyllisa indiae, commonly referred to as the Indian mango mite, is a microscopic pest belonging to the Eriophyidae family and the Trombidiformes order. These mites are characterized by their extremely small size and their unique four-legged body structure, which allows them to hide within the smallest crevices of plant tissue.

This pest is known primarily for infesting Mangifera species, particularly mango trees. It attacks the meristematic tissues, buds, and young leaves of the host plant. By feeding on the internal fluids of the plant cells, it disrupts normal physiological processes, severely stunting the growth of the affected plants.

The biology of Acaphyllisa indiae is marked by a rapid life cycle consisting of egg, nymphal stages, and adult phases. The mites prefer the sheltered environments of leaf axils and terminal buds. Their development is highly dependent on ambient temperature, allowing for rapid population growth when conditions are optimal, often leading to outbreaks within an orchard.

Symptoms of infestation include leaf curling, chlorosis, and the development of abnormal growths such as witches' brooms. This physical damage reduces the photosynthetic capacity of the plant and limits flower production, which directly translates to reduced fruit yields and lower quality of the harvest, impacting the overall profitability of the crop.

Effective management and protection strategies for Acaphyllisa indiae require a multi-faceted approach, including:

• Regular monitoring and scouting of terminals for early infestation signs;
• Sanitary pruning to remove and destroy heavily infested branches;
• Application of targeted acaricides during the peak activity periods;
• Promotion of biological control agents, such as predatory phytoseiid mites;
• Implementation of robust nursery hygiene to prevent the introduction of the pest into new areas.
