The present investigation entitled “Integrated Management of Cabbage Aphid (Brevicoryne brassicae L.)” was carried out at Department of Entomology as well as field of Vegetable Research and Demonstration Block, College of Horticulture, VCSG Uttarakhand University of Horticulture and Forestry, Bharsar, Pauri Garhwal during 2022. Seasonal incidence of Cabbage aphid (Brevicoryne brassicae) revealed that the maximum numbers of aphid, (784.05 nymphs/plants and 506.32 adults/plants) were recorded during 23rd SMW viz., 2nd week of June. Correlation studies indicated that aphid population exhibited highly significant positive correlation with maximum temperature and minimum temperature and significant negative correlation with morning and evening relative humidity. While rainfall showed non-significant positive correlation with aphid population. Efficacy of different treatments (Cultural practices (Weeding) + Yellow sticky trap), (Garlic extract + Red pepper extract), (Onion extract + Yellow sticky trap), (Neem leaf extract + Cow urine), (Thiamethoxam 25 WG + Beauveria bassiana), (L-cyhalothrin 5 EC + Beauveria bassiana) and (Biological control + Mechanical control) were evaluated by two sprays at 3, 5 and 7 days interval against aphid (B. brassicae) during year 2022. After 1st and 2nd application highest reduction in aphid population (77.37 and 93.57) and maximum yield (5.85 kg/plot and 541.66 q/ha) over pre treatment was recorded in L-cyhalothrin 5 EC incorporated with Beauveria bassiana.
