Leptoglossus vexillatus

Leptoglossus vexillatus belongs to the family Coreidae, commonly known as leaf-footed bugs. This insect is recognized as a significant agricultural pest capable of causing substantial damage to various plant species, particularly in warmer climatic zones.

The pest targets a diverse range of hosts, including vegetable, fruit, and ornamental plants. It is frequently observed on members of the Cucurbitaceae, Solanaceae, and Fabaceae families, where both adults and nymphs feed on the sap of vegetative parts and developing fruits.

The biology of Leptoglossus vexillatus follows a typical life cycle consisting of an egg stage, five nymphal instars, and the adult stage. Equipped with piercing-sucking mouthparts, these insects penetrate the plant tissue to extract fluids, which disrupts the physiological processes of the host plant.

Damage symptoms include the appearance of necrotic spots, leaf deformation, and the wilting of shoots. Infestation of fruits often leads to premature abscission, reduced market value, and diminished crop yields, posing a major challenge for farmers.

Effective management strategies require an integrated approach. This includes cultural practices such as the removal of host debris and the judicious use of systemic insecticides. Consistent field scouting during the growing season is essential to detect pest populations early and prevent widespread economic loss.
