Biological efficacy of selected insecticides for the control of the green apple aphid Aphis pomi (de Geer, 1773) on apple in Bulgaria

The aim of this study was to evaluate the biological efficacy of chemical insecticides, from different chemical classes, recommended for the control of the apple aphid Aphis pomi in apple orchards in Bulgaria. The experiment was carried out in 2023 in the experimental field of Agricultural University-Plovdiv. The insecticides tested were spirotetramat (Movento 100 SC), flonikamid (Teppeki) and acetamiprid (Mospilan 20 SG). The insecticides were applied at the concentrations recommended for the control of this and other pests. All the tested chemical insecticides showed very high biological efficacy, therefore they can be recommended as suitable for efficient control of Aphis pomi on apple.
