Impact of Success Bait (a.i. spinosad) against Rhagoletis cerasi on insect fauna in field test

Cherry fruit fly is the most important pest of cherries in Croatia. Pest control against the cherry maggot in commercial orchards is difficult because of cherry fruits ripening time and long life of insecticides. In Croatia organophosphate insecticides and synthetic pyrethroids are recommended for the control of Rhagoletis cerasi. In the frame of IOBC definition for Integrated Production, priority should be given to ecologically safer methods, minimizing the undesirable side effects to enhance the safeguards to the environments and human health. Spinosad is one of the Naturalytes that is recommended against Vine moths in Croatia. Plant protection against fruit flies in IPP uses attract and kill technique as ecologically safer method. Success Bait is recommended for control of Med fly in citrus orchards and olive fruit fly on olives in Croatia. We want to know efficacy of Success Bait against Rhagoletis cerasi and its advantages in comparison with common insecticides against European cherry fruit fly. Investigation was carried out in a commercial sour cherry orchard of Borinci near Vinkovci, Slavonia County in Croatia. Experiment with Success Bait was done on 0.5 ha of cherries ; organphosphate insecticides and synthetic pyrethroids treated on the other part (25 ha) of the cherry orchard. When the cherries were ripe infestation evaluation was checked on several hundreds of fruits. The fauna observation was carried out in both plots eight days after treatment by branch-beating method. The first results of the experiment have shown the same efficacy on Rhagoletis cerasi in the different tretaments, and more beneficial insects were present in the part where Success Bait was used than in the part where pyrethroids and OPs insecticides were used.
