BIOLOGICAL TOOLS FOR CONTROLLING THE MAIN PESTS OF SWEET CHERRY

Abstract

The paper presents the data collected from an ecological plot of sweet cherries with an area of 0.5 ha, where different methods of monitoring and combating the main pests were tested: European cherry fruit fly - Rhagoletis cerasi L. and black cherry aphid - Myzus cerasi F. The study took place during the years 2019-2020. European cherry fruit fly monitoring - Rhagoletis cerasi L. was performed with both atraCERAS optical panels and Decis Trap devices, with both a warning and control role, the results obtained highlighting a similar flight dynamics. The control of the European cherry fruit fly, carried out by direct control with the help of Decis Trap devices, the dose of 100 traps / ha, proved to be effective, the Abbott effectiveness indicator registering values between 83.4 - 90.5% in 2019, respectively 81.6 - 87.8% in 2020, depending on the studied variety. To control the black cherry aphid - Myzus cerasi F., the product Prev-Am was mainly used, based on orange oil, which was used with good results for the first attacks observed.
