Lonchaea urubambana

Lonchaea urubambana is a species of fly belonging to the family Lonchaeidae (lance flies) in the order Diptera. These insects are specialized pests whose larvae develop inside fruit tissues, which makes their early detection during infestations significantly difficult for growers.

The pest primarily targets tropical and subtropical fruit crops. It is most commonly reported damaging various species of passion fruit (Passiflora), where the larvae feed directly on the fruit pulp, leading to premature fruit drop or rapid decay of the harvest.

The biology of this species is closely linked to the phenological stage of the host plant. The adult fly deposits eggs under the skin or into damaged areas of the fruit. Upon hatching, the larvae bore into the fruit tissue, undergo several developmental stages, and eventually pupate either within the fruit debris or in the topsoil layer.

The damage profile is defined by the larval tunneling activities, which turn the interior of the fruit into a decayed mass. The primary economic impact includes loss of marketability, rot caused by secondary pathogens invading the fruit, and a substantial decrease in overall yields within commercial fruit orchards.

Control measures require an integrated approach:

• collecting and destroying fallen fruit immediately to break the life cycle;
• deploying pheromone traps to monitor adult population levels;
• applying registered insecticides during peak flight periods;
• maintaining rigorous horticultural practices to improve plant vigor and natural resistance.
