Trigona trinidadensis

Trigona trinidadensis is a species of stingless bee belonging to the order Hymenoptera and the family Apidae. While many members of the genus Trigona are recognized as beneficial pollinators, this specific species is classified as a plant pest due to its destructive behavior toward plant tissues in certain environmental contexts.

This pest is primarily found in the tropical regions of Central and South America. It affects a wide range of agricultural crops, including citrus fruits, tropical orchards, and ornamental plants. The damage is primarily caused by worker bees that physically attack young shoots, bark, and buds while foraging for plant resins and secretions needed for nest construction.

The biology of Trigona trinidadensis is characterized by a social lifestyle with a complex caste system. They establish colonies in tree hollows or crevices. The developmental cycle progresses through egg, larva, pupa, and adult stages. Pest activity typically increases during periods when natural floral resources are scarce, leading bees to feed on plant tissues instead.

The nature of damage includes deep abrasions on the bark, gnawing of tender buds, and surface damage to developing fruits. This physical impact leads to stunted growth, fruit malformation, and a significant loss in crop quality. Furthermore, the damaged plant tissues serve as entry points for secondary pathogens, such as fungi and bacteria, which can cause severe rot and tree decline.

Effective management strategies include:

• Mechanical removal or relocation of nests found near agricultural fields.
• Utilization of protective netting to shield young, vulnerable plants from foraging bees.
• Application of bio-based repellents to discourage bees from landing on sensitive crop structures.
• Implementation of regular sanitary pruning to remove damaged wood and improve tree health.
