Bephratelloides

Taxonomic position: Bephratelloides belongs to the order Hymenoptera, family Eurytomidae. These are specialized insects characterized by a larval stage that develops entirely within the host plant tissue, typically inside fruits or seeds.

Host plants: The pest primarily targets members of the Annonaceae family. It is a major economic threat to sugar apple (Annona squamosa), soursop (Annona muricata), and other related species cultivated in tropical and subtropical regions across the globe.

Biology and lifecycle: The adult Bephratelloides is a small wasp. The female uses her ovipositor to pierce the skin of developing fruit and deposits eggs directly into the pulp or seeds. Larvae feed on the internal tissues, progressing through several instars before pupating inside the fruit. The duration of the cycle varies based on regional environmental factors.

Damage and economic impact: The damage is internal and often remains undetected until significant destruction has occurred. Larval feeding creates tunnels throughout the fruit, leading to premature fruit drop, secondary rot infections, and complete market rejection of the crop. This pest is a major quarantine concern for countries exporting tropical fruit.

Control measures: Managing Bephratelloides requires an integrated approach due to the protected nature of the larvae within the fruit:

• Strict orchard sanitation, including the collection and disposal of fallen and infested fruits.
• Fruit bagging, which provides a physical barrier against female wasps.
• Monitoring adult activity using sticky or pheromone traps to time interventions.
• Strategic application of insecticides during the initial fruit setting period to prevent oviposition.
