The aim of the present research work was to investigate the impact of planting dates on thrips populations in onions was monitored throughout two growing seasons and field experiments were carried out for two years (2013-14 to 2014-15) to determine the Impact of planting dates on Thrips tabaci Lindeman infestation and yield in onion (Allium cepa L.) in central part of India. Plant samples were collected to assess Impact of planting dates on thrips and their abundance. Results showed that the significantly lowest population of onion thrips was recorded on 1st November transplanted onion crop (12.97 thrips/plant), while significantly highest population of onion thrips was recorded on 15th January transplanted onion crop (34.25 thrips/plant). Significantly higher yield was recorded in 1st January transplanted crop (275.83 q/ha), while significantly lowest yield was recorded in 1st November transplanted crop (236.30 q/ha).
