Mango bud mite

The mango bud mite (Tegonotus mangiferae) belongs to the Eriophyidae family. It is a microscopic pest that cannot be seen with the naked eye.

These mites have a distinctive worm-like body, usually yellowish or white, which allows them to hide effectively within plant tissues.

Taxonomically, they are part of the order Trombidiformes. Their entire development cycle is strictly confined to the host plant's tissues.

They predominantly reside and overwinter beneath the bud scales of mango trees, providing them with protection against external threats.

Dispersal occurs mainly through wind currents, insect vectors, or the accidental movement of infested nursery stock between different regions.

The primary host for this pest is the mango tree (Mangifera indica). It attacks the developing tissues of both vegetative and floral buds.

By feeding on the sap of young tissues, the mites cause physical damage and alter the growth patterns of the affected parts of the plant.

Severe infestations can lead to significant economic losses, particularly in orchards where fruit set is compromised by damaged flower panicles.

The mite's activity inhibits normal physiological processes in the plant, weakening the tree and making it susceptible to secondary environmental stress.

Reduced terminal growth and stunted branch development are common consequences of persistent mite feeding on the tree's meristematic tissues.

The formation of galls — abnormal tissue growth — is the most definitive sign of an infestation, as mites feed and reproduce within these structures.

Infected buds often appear distorted, dry, or fail to sprout entirely, preventing the development of healthy leaf or flower branches.

Leaves that do manage to emerge from infested buds may show chlorosis, curling, or patchy necrosis due to previous mite damage.

A "witches' broom" appearance, characterized by stunted and highly branched twig clusters, is frequently observed in heavily infested mango trees.

Deformed and sterile floral panicles that do not produce fruit are major indicators of the mite's presence within the reproductive structures of the tree.

Mechanical removal and destruction of infested buds and panicles are essential to prevent the spread of the mite population throughout the orchard.

Chemical control involving systemic and contact acaricides should be applied during the early stages of bud burst when mites are most exposed.

Regular monitoring of the orchard is necessary to identify early signs of infestation and implement control measures before the population explodes.

Quarantine measures and the use of certified mite-free nursery plants are critical steps for preventing the introduction of this pest into new orchards.

Biological control, such as encouraging natural predatory mite populations, plays a vital role in maintaining the pest at non-damaging levels naturally.
