Fulgora castresii

Systematic position: The insect Fulgora castresii belongs to the order Hemiptera and the family Fulgoridae (lanternflies). It is a tropical species characterized by a distinct cephalic process, which makes it a recognizable representative of this insect group.

Target crops: This pest primarily affects woody plants in tropical and subtropical regions. In an agricultural context, it can pose a significant threat to fruit tree plantations by feeding on the sap of young shoots and branches, which leads to a decline in the overall vigor of the host plant.

Biology and life cycle: The life cycle of Fulgora castresii comprises the egg, nymph, and adult (imago) stages. Reproduction occurs during warmer seasons, with females laying eggs on tree bark and covering them with protective secretions. Nymphs, like the adults, are highly active and migrate along branches to find the most nutritious areas for feeding.

Nature of damage: The primary damage is caused by the insect piercing plant tissues with its stylet to extract sap. This leads to the deformation of young shoots, premature leaf drop, and reduced plant immunity. An additional secondary risk includes the growth of sooty mold on the insect's honeydew excretions, which inhibits photosynthesis.

Protection measures: Management of this pest requires a combination of agrotechnical and chemical approaches. Essential practices include regular sanitary pruning of infested branches and maintaining tree vitality. In cases of high infestation, the application of systemic insecticides approved for specific crops is recommended, ensuring strict adherence to pre-harvest intervals and dosage rates.
