Use of cyantraniliprole in control of Rhagoletis cerasi in sweet cherry and its residues
The objective of this study was to evaluate the efficacy of cyantraniliprole against R. cerasi and its dissipation rate in sweet cherry fruits. Cyantraniliprole is a second-generation of anthranilicdiamide insecticide, with unique mode of action that involves activating ryanodine receptors. It is a reduced-risk insecticide, with a very low toxicity to vertebrates and non-target organisms. The field trials were carried out in the orchards near Novi Sad, Serbia, according to EPPO standards for experimental design and data analysis. Cyantraniliprole (100 g a.i. L‑1) was applied at 0.5-0.75 L ha‑1. The efficacy (E, %) of insecticide was calculated according to Abbott. After the application of cyantraniliprole, in the harvest period, the number of R. cerasi larvae in sweet cherry fruits was on a significantly lower level in relation to the control, with efficacy of 89.3-94.9%, depending of localities and applied doses. Sampling of sweet cherries was performed by randomly collecting the fruits from various places of the experimental plots. For the determination of cyantraniliprole residues, the QuEChERS method coupled with HPLC-DAD was carried out. Method validation was performed taking into consideration linearity, recovery, precision, matrix effect, limits of detection and quantification. The obtained results completely fulfilled the SANTE/11945/2015 criteria. The applied insecticide cyantraniliprole dissipates rapidly in sweet cherry fruits, with half-life of 3.0 days.
