Abstract:
The field experiment was carried out at AICRP on Forage Crop and Utilization, M.P.K.V, Rahuri (M.S.) during Rabi 2019-2020. During the study of seasonal abundance, oat aphid noticed in middle of December 2019 (13.90 aphid/tiller). Thereafter, population of oat aphid showed increasing trend up to middle of February, 2020 (93.20 aphid/tiller). Population of oat aphid decreased thereafter and lowest population was noticed during first week of March, 2020 (12.50 aphid/ tiller). Oat aphid showed negative correlation with minimum temperature and positive correlation with coccinellid predators and Chrysoperla.

Population of oat aphid decreased thereafter and lowest population was noticed during first week of March, 2020 (12.50 aphid/ tiller). Oat aphid showed negative correlation with minimum temperature and positive correlation with coccinellid predators and Chrysoperla.
Lady bird beetles were active throughout the crop season; initial population was noticed during last week of December, 2019 (01 LBB/tiller). The population of grub of lady bird beetles started increasing simultaneously with aphid population and reached to its peak during first week of February, 2020 (3.40 LBB/tiller). The lady bird beetle population was negatively correlated with minimum temperature and chrysoperla and positively with oat aphids.
