Abstract
‘HoneySweet’ is a genetically engineered plum resistant to Plum pox virus. Potential risks such as its impact on the diversity and dynamics of indigenous aphid populations was assessed. The study compared winged population of aphids visiting transgenic and conventional plums under continental temperate climatic conditions of Romania. The experimental analysis was conducted during three years (2016-2018) within an experimental plot containing transgenic (‘HoneySweet’) and conventional (‘Reine Claude d’Althan’ and ‘Stanley’) plums. This study revealed a similarity of both flight curves and the number and species of aphids landing on the two types of plum. Overall results showed no statistically differences between aphid species visiting the three cultivars, respectively the two types of plum. Consequently, our results support the hypothesis of the neutral effect of the transgenic plum on indigenous populations of aphids.
