Bephratelloides pomorum

Bephratelloides pomorum is a specialized insect pest belonging to the order Hymenoptera and the family Eurytomidae. This species is widely recognized as one of the most significant pests affecting plants within the Annonaceae family, particularly targeting species such as Annona squamosa and Annona muricata.

The primary hosts of this insect are the fruits of the Annona genus. Given the economic value of these fruits in tropical and subtropical agriculture, the presence of this pest poses a severe threat to commercial plantations, often leading to substantial crop failures if not properly managed.

The biological cycle of this pest is highly adapted to the fruit development period. The female wasp deposits eggs inside the young developing fruit using its ovipositor. The emerging larvae feed on the internal tissues and seeds, creating tunnels that damage the structural integrity of the fruit throughout their development and pupation stages.

Damage caused by this insect is characterized by the premature drop of fruits and the presence of small emergence holes on the fruit surface. These holes not only indicate infestation but also provide entry points for secondary pathogens, leading to fruit rot and making the produce unsuitable for harvest or consumption.

Management and control strategies for this pest require a combination of cultural and preventive measures:

• Consistent collection and destruction of infested and fallen fruits to break the life cycle.
• Bagging of individual fruits to prevent female wasps from accessing the surface for oviposition.
• Application of biological control agents, including entomopathogenic fungi, to reduce wasp populations.
• Judicious use of chemical control during the early stages of fruit set, following strictly regulated intervals and safety guidelines.
