An effect of Abamectin 18 g/l on the seasonal abundance of two-spotted spider mite (Tetranychus urticae Koch.) was studied in greenhouse cucumbers in 2005–2006. An efficiency of Abamectin 18 g/l 0.12% against two-spotted spider mite was: 81.7–100% 3 days after treatment, 98.4–100% 7 days after treatment, 100% 9–10 days after treatment, 98.7–100% 14 days after treatment. An efficiency of insecticide Abamectin 18 g/l 0.1% against two-spotted spider mite was: 77.5–90.1% 3 days after treatment, 96.7–100% 7 days after treatment, 99.2–99.4% 9–10 days after treatment, 88.1–100% 14 days after treatment. An efficiency of insecticide Abamectin 18 g/l 0.075% against two-spotted spider mite was: 72.7–81.0% 3 days after treatment, 87.0–100% 7 days after treatment, 100% 9–10 days after treatment, 84.7–100% 14 days after treatment. An efficiency of insecticide Abamectin 18 g/l 0.05% against two-spotted spider mite was: 45.6–78.0% 3 days after treatment, 88.5–100% 7 days after treatment, 82.3–100% 9–10 days after treatment, 85.5–100% 14 days after treatment.
