Fruit fly Ceratitis gravinotata

Systematic position: Ceratitis gravinotata belongs to the order Diptera, family Tephritidae. These flies are widely recognized for their potential to cause significant damage to fruit production and are closely monitored by plant protection organizations due to their invasive nature.

Host crops: The species is a significant pest of various horticultural crops. It primarily infests fleshy fruits, including citrus, stone fruits, and tropical fruits. Its broad host range makes it a consistent threat to fruit orchards across its range, as it can adapt to various environmental conditions.

Biology and life cycle: The lifecycle follows a complete metamorphosis including egg, larva, pupa, and adult stages. Females pierce the fruit skin to deposit eggs inside. Larvae feed on the fruit pulp, leading to rapid tissue breakdown. Once fully grown, the larvae exit the fruit and drop to the ground to pupate in the soil, emerging later as adult flies.

Damage and economic impact: The primary economic damage is caused by larval feeding, which destroys the internal structure of the fruit. This infestation leads to premature fruit drop, secondary fungal infections, and complete loss of marketability. In severe cases, infestations can destroy a significant percentage of the harvest, impacting local and international trade.

Control measures: Management of Ceratitis gravinotata requires an integrated approach. Key strategies include:

• Strict sanitation practices, including the removal and destruction of fallen fruits to prevent larval development.
• The deployment of monitoring traps baited with attractants or pheromones to detect population peaks.
• The use of targeted chemical sprays and bait stations to reduce adult fly density.
• Implementation of quarantine protocols to prevent the spread of infested fruit to new areas.
