Lamprolonchaea

Lamprolonchaea is a genus of insects from the order Diptera, belonging to the family Lonchaeidae, commonly known as lance flies. In agricultural practice, this pest is recognized as a dangerous phytophage capable of damaging the fruits of various crops, particularly in subtropical and tropical climates.

This pest affects a wide range of crops, but causes the most significant economic damage to figs, citrus fruits, tomatoes, and occasionally grapes. The larvae bore into ripening fruits, creating tunnels that lead to rapid rot and the loss of the product's commercial value.

The biological life cycle consists of four stages: egg, larva, pupa, and adult. Females lay eggs directly under the skin of the fruit or into existing damage sites. Upon hatching, the larvae feed on the pulp, after which they exit the fruit to pupate in the soil or among fallen leaves.

Damage symptoms include premature fruit drop, the appearance of dark spots, and softening of tissues. Inside the fruits, secondary fungal and bacterial infections often develop, which accelerate the decomposition process. The pest's high fecundity allows it to produce multiple generations within a single season.

For effective control against Lamprolonchaea, a comprehensive approach is required. Agronomic practices include regular collection and destruction of fallen fruit, deep tillage of the soil around the tree base, and timely pruning. Chemical control involves insecticide applications during the mass flight of adults, although the use of products must be strictly regulated based on the crop's ripening stage.
