Abstract:
An experiment was conducted to observe the seasonal incidence of insect pests on okra in Kharif- 2018 and 2019 at the College of Agriculture, RVSKVV, Gwalior (M.P.). The activity of red cotton bug was recorded from in the month of September and its peak population of bug was recorded from month of October, in both the years. Showed that the population of mealybug from third week of august (34^th SMW) with population 0.6 bugs/plant and its peak population was observed from first week of October in 2018 (40^th SMW) and fourth week of September in 2019 (39^th SMW) with 0.4 beetles/plant in both the years. The red cotton bug showed negatively non-significant correlated with maximum temperature, minimum temperature, evening relative humidity and evaporation in both the years. Significantly positive correlated with minimum temperature and evaporation (r= 0.34, 0.82 and r= 0.41, 0.79, respectively) with mealybug in both the years and blister beetle had significant positive correlation (r= 0.37, 0.72, r= 0.27, 0.21, r= 0.40, 0.78 and r= 0.42, 0.69) with minimum temperature, morning and evening relative humidity and evaporation in 2018 and 2019, respectively.
