For scientific purpose, 3D traps mimicking a botanical flower organ in five varieties of shape, three varieties of sizes and two colors (blue and yellow) were created to monitor the emergence of western flower thrips Frankliniella occidentalis Pergande. A methodology has been developed for their application to cucumbers, second crop, in greenhouse conditions at the experimental base of "Opora Zaden Bulgaria" Ltd. in the village of Tsalapitsa. The effect of the traps was observed along the height of the stem at three points from the soil surface, at equal distances (15 cm, 30 cm and 45 cm). Reported results are based on placement of traps along the plant stem, size and color of the trap. Fixing the traps up to a height of 45 cm, in three points along the stem of the plant has a positive effect on reducing the population of western flower thrips (F.occidentalis). The best efficiency for monitoring the pests was achieved when placing the flower model traps at a height of 15 cm from the soil surface. In addition to western flower thrips, the presence of tomato mining moth (Tuta absoluta Meyrick) and bioagents was recorded in the traps. The color of the flower model trap affects the monitoring result. The yellow color is attractive to all types of pests and bioagents in the greenhouse, and the blue color only attracts thrips.
