Challenges of IPM Methodology in Citrus Fruits. Control of Ceratitis Capitata Wied. in Clementines in the Citrus Production Area of South Tarragona

The Mediterranean fruit fly (Ceratitis capitata Wied.) attacks mature or almost-mature fruit. Therefore, any plant protection treatments applied are very close to the harvesting period, which may result in residues on the fruit. Furthermore, in citrus fruits, early varieties of mandarins are harvested at the peak incidence time for the pest, which increases the likelihood of affected fruit on which symptoms are not yet observed going into storage.

The degreening of these early varieties facilitates the development of Mediterranean fruit fly eggs and larvae in harvested mandarins. The US is a very large market for clementines from south Tarragona, and as this is a quarantine pest, the presence of a single affected fruit means that the entire batch is rejected under the agreement for exporting Spanish clementines to the US. Mass trapping is a very good system to combat the fruit fly in all varieties of early clementines.

When the capture threshold of one male per trap per day is exceeded, mass trapping should be complemented with a 'bait' treatment using Spinosad. It is also necessary to take into account the specific residue requirements of various European supermarket chains, which are often very restrictive and not entirely underpinned by technical criteria.
