Abstract:
A field trial was conducted at the Commercial Horticulture Unit of Birsa Agricultural University, Kanke, and Ranchi during rabi season of 2016-2017 and 2017-2018, in order to monitor the incidence and abundance of leafhopper. The activity of leafhopper started soon after the transplanting. The serious activities were noticed from 34th August 2016 to second January 2017. The highest leaf hopper number per leaf was found as (12.0/3 leaves) at maximum temperature and minimum temperature 24.6O C and 4.8oC, respectively. The correlation was found positive and highly significant (r= -0.666**) with maximum temperature (r= -0.666**) and (r = -0.536*) minimum temperature. The maximum relative humidity and minimum relative humidity was (r = 0.288) and (r = -0.096) respectively observed the positively non-significant and positively non-significant correlation with population of leafhopper. In the year 2017-18, the peak (11.6/ 3 leaves) activity of leafhoppers was recorded at 46th SMW. The pest was active throughout the season with a fluctuation range of 0.0 to 11.6 aphid per three leaves. The abiotic factors together were able to explain up to the extent of 78-74 per cent population dynamics fluctuation in leafhopper.
