The results of two-year researches on studying the efficiency of insecticide biotline (tanrec) against aphids (Aphis pomi Deg., Dysaphis plantaginea Pass., Yezabura reaumuri Mordu, Myzus cerasi F., Hyalopterus pruni Geoffr., Aphis grossularie Kalt.) on seed, stone fruit crops, and small-fruit crops realized in the conditions of the Republic of Belarus were presented. The field experiments took place on separate trees (apple (Malus), pear (Pyrus), cherry (Cerasus), plum (Prunus)) and bushes (black currant (Ribes nigrum L.)) against the natural background of pest development in the conditions of the different number of their initial quantity. It was determined that aphid losses after a single application of a studied preparation were 95,5-100% in comparison with the control variant. The insecticide effectively suppressed the phytophage development both in the conditions of low and high initial pest population density. Biotline, WSC (imidaclopride, 200 g/l) was approved for its single application (at the rate of 2,5 ml per 10 l of water) on apple and black currant plants against aphids before the blossoming stage
