The research trials were conducted at research cum instructional farm, College of Agriculture, IGKV, Raipur (C.G) for two consecutive Rabi seasons of 2020-21 and 2021-22. The major pest of the linseed crop in Chhattisgarh was linseed budfly, Dasyneura lini, observed during both cropping seasons. The peak activity of linseed budfly was observed during 10th standard meteorological week of year 2020-21 and 2021-22, respectively. During this period, the correlation of maximum temperature was found positive significant and the correlation of relative humidity I and II was found negative significant whereas, all the other parameters showed the positive and negative non-significant correlation with the mean population of D. Lini.

Abstract

The research trials were conducted at research cum instructional farm, College of Agriculture, IGKV, Raipur (C.G) for two consecutive Rabi seasons of 2020-21 and 2021-22. The major pest of the linseed crop in Chhattisgarh was linseed budfly, Dasyneura lini, observed during both cropping seasons. The peak activity of linseed budfly was observed during 10th standard meteorological week of year 2020-21 and 2021-22, respectively. During this period, the correlation of maximum temperature was found positive significant and the correlation of relative humidity I and II was found negative significant whereas, all the other parameters showed the positive and negative non-significant correlation with the mean population of D. Lini.
