Abstract:

The population dynamics of thrips, Thrips tabaci Lindemann along with their correlation with abiotic factors were studied during 2014 and 2015 at the Cotton Research Area, CCS Haryana Agricultural University, Hisar. During the 1st season, the incidence of thrips was recorded from the 27th SMW (standard meteorological week) onwards and reached to its peak at 33rd SMW with the range of 12.89 to 58.27 thrips/leaf. The maximum and minimum mean thrips population was recorded in RCH 314 BGII (16.13thrips/leaf) and H 1226 (3.52thrips/leaf) genotype, respectively. During the 2nd season the incidence of thrips was commenced at 25th SMW. The peak of the thrips population reached in 31st SMW and it ranged from 14.68 to 36.85 thrips/leaf. The minimum mean thrips population of 4.64 nymphs/leaf was recorded in the H 1226 genotype whereas RCH 314 BGII had the maximum mean thrips population of 13.02 nymphs/leaf. Correlation studies revealed that during 1st season all the weather parameters were non-significantly correlated with the thrips population whereas, during 2nd season maximum temperature correlated significantly negative with thrips population while minimum temperature, morning and evening relative humidity correlated significantly positive.
