Phytosanitary Treatments Against Bactrocera dorsalis (Diptera: Tephritidae): Current Situation and Future Prospects

Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is arguably the most important tephritid attacking fruits after Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). In 2003 it was found in Africa and quickly spread to most of the sub-Saharan part of the continent, destroying fruits and creating regulatory barriers to their export. The insect is causing new nutritional and economic losses across Africa, as well as the losses it has caused for decades in infested areas of Asia, New Guinea, and Hawaii. This new panorama represents a challenge for fruit exportation from Africa. Phytosanitary treatments are required to export quarantined commodities out of infested areas to areas where the pest does not exist and could become established. This paper describes current phytosanitary treatments against B. dorsalis and their use throughout the world, the development of new treatments based on existing research, and recommendations for further research to provide phytosanitary solutions to the problem.
