Indian Journal of Entomology, 2022.A field experiment was conducted at Entomology farm, Faculty of Agriculture, SKUAST-K during rabi, 2019-20 to study the population dynamics of Thrips tabaci Lindeman in onion. The incidence of adults (31.00/ plant) and immatures (61.00/ plant) was observed from 9th standard meteorological week (SMW). It reached a peak on 22nd and 21st SMW and declined

Population dynamics of thrips was studied at three different dates of transplanting (12th Dec’ 2017, 22nd Dec’ 2017 and 12th Jan’ 2018) on the “Agrifound Light Red” onion variety. The highest population of nymphs and adults of thrips was recorded on 3rd DOT (270 ± 8.65) followed by 2nd DOT (164 ± 8.22) and 1st DOT (129 ± 8.22).
