Because of the weather in 2018, cherry orchards have to deal with all kinds of problems: monilia, botrytis, flies, Drosophila, aphids an even forficulae. The produce of those who did not intervene at the right time will be heavily damaged.
A technical day organised by Crpv and Consorzio Ciliegia di Vignola Igp was held on June 14th, 2018 in Vignola (Modena). Stefano Caruso and Giacomo Vaccari from Consorzio Fitosanitario Modena talked about the Drosophila suzukii situation and monitoring and trapping solutions.
"The Drosophila population seemed low after winter, but it was just an illusion. Those who did not carry out treatments or cover orchards with nets will not manage to save the fruit. It's a difficult year also thanks to the higher presence of monilia. Rhagoletis cerasi is also back. This year is looking very difficult."
Giacomo Vaccari displayed the three most popular traps currently being experimented. The first uses a mix of wine and apple vinegar called Drosky Drink as bait. The problem is that it must be renewed every week. It's useful when winter ends to monitor generations, but it's less effective in the veraison period.
The second model also uses vinegar but it's active for longer.
The third model has a very selective bait type and deltamethrin on the top part of the lid. The kit lasts one season and it's still being experimented.
"As regards mass capturing, it would be important to establish area plans rather than just company plans. A large area should be treated to contain the Drosophila population, otherwise an abandoned cherry orchard risks becoming an inoculation site."
Crpv also set up an exhibition at the Vignola Fresh Produce market. The main varieties were illustrated by Danieel Missere and Chiara Etiopi.
