Summary of the Express Pest Risk Analysis for Bactrocera dorsalis (Hendel)


Bactrocera dorsalis (Oriental fruit fly) is a species of tephritid fruit fly, which larvae infect tropical fruits, but also some species cultivated in the temperate zones, including PRA area.

Mated female punctures the skin of mature fruit and deposit eggs below the skin of the host fruit. Larvae feed on the flesh of the fruit. Infected plants are perishable. Oriental fruit fly couses serious economic losses in cultivations (losses can be up to 100% of unprotected fruit). Traps (liquid bait), male suppression, pesticides are the most effective control techniques against Bactrocera dorsalis.

Fruits import from area of Bactrocera dorsalis occurence is the most likely way of pest entry. The pest impact in PRA area will be lower then on its native range, because pest needs high temperatures to develop (B. dorsalis will not develop at temperatures below 13°C). Additional, host plants are grown in fields in PRA area which also reduce the posibility of pest establishment. Potential losses may be in cultivations close to area of adults flight.

Pest monitoring and traps should be the basic phytosanitary measures. If those methods will be unsufficient other eraditation methods should be consider.
