TESTING OF SEMIO-CHEMICAL PRODUCTS IN MONITORING AND CONTROL OF Rhagoletis cerasi L.

This paper aims to monitor the cherry fruit fly, as well as for possible actions to combat it by non-chemical methods. The Entomology Department of the USAMV Cluj-Napoca in collaboration with the UBB Cluj-Napoca researchers, started a study regarding the functionality of some Semi-chemical products to attract adults of Rhagoletis cerasi L. The chemistry research laboratories synthesized them and then, under natural conditions, screening studies of their attraction power were performed. The experiment was conducted over two experimental years, 2016 and 2017. Six variants of semiochemical formulations were tested: 2-hexanone, 3-heptanone, nonanal, beta-felandren, geranil acetate and (+) –limonen. The V6 variant that blends the acetylation made most capture. Therefore, the mixture of volatile substances in this variant may present a higher level of attractiveness.
