Monalonion velezangeli

Monalonion velezangeli belongs to the order Hemiptera and the family Miridae. It is a well-known mirid bug species that has become a significant economic concern in regions dedicated to the cultivation of tropical crops, particularly in South and Central America.

The primary hosts for this pest include cacao (Theobroma cacao) and avocado (Persea americana). Its ability to pierce the skin of developing fruits and stems allows it to feed on plant sap, significantly impacting the growth and yield of the host crops.

The life cycle of the pest is completed through several nymphal instars before reaching adulthood. The insect is highly prolific, and under favorable tropical conditions, its generations overlap, making it difficult to control through simple mechanical means alone.

Damage caused by Monalonion velezangeli includes visible pitting, scarring on the surface of the fruit, and structural weakness of the branches. Furthermore, the lesions created by the bug act as entry points for secondary pathogens, such as fungi, which exacerbate the overall crop loss.

Management strategies for this pest include:

• Implementing regular scouting to detect initial infestation levels.
• Pruning and destroying infected branches to lower the pest population.
• Utilizing biological control methods, including entomopathogenic fungi.
• Applying systemic or contact insecticides only when necessary to preserve beneficial insect populations.
