  To evaluate the effect of row-to-row distance of onion plants on thrips population, an experiment was conducted in Quetta, Pakistan. Five line spacing (20, 25, 30, 35 and 40 cm) with constant 20 cm plant-to-plant distance were tested. An inverse relation was found between increased line spacing and thrips population. Maximum mean number of thrips (162.4 plant-1) was observed on the plants cultivated in 20 cm apart rows with minimum yield (20310 kg ha-1). Minimum mean number of thrips (96.20 and 98.55 plant-1) was recorded from T5 (40 cm RxR distance) and T4 (35 cm RxR distance) with 20380 and 21250 kg ha-1 yield, respectively. Optimum number of thrips (114.3 plant-1) was recorded on plant cultivated in 30 cm apart lines with maximum yield (28250 kg ha–1). 30 cm row-to-row distance with 20 cm plant-to-plant distance in onion is recommended as an Integrated Pest Management (IPM) tool to culturally control thrips in the crop.
