    STUDIES ON POPULATION DYNAMICS AND MANAGEMENT OF MAJOR INSECT-PESTS OF BLACK GRAM [Vigna mungo (L.) HEPPER] IN SOUTHERN-EASTERN ZONE OF RAJASTHAN
    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2021-12-06) MEENA, MANGAL SUKHI; Meghwal, H. P.
    The present investigation entitled “Studies on Population Dynamics and Management of Major Insect-Pests of Black gram [Vigna mungo (L.) Hepper] in Southern-Eastern Zone of Rajasthan” was conducted at experimental farm, Agricultural Research Station, Ummedganj-Kota (Rajasthan) during kharif 2020. The initiation of bihar hairy caterpillar (0.26 larvae/mrl), spotted pod borer (0.13 larvae/mrl) and tobacco caterpillar (0.13 larvae/mrl) were started during 32nd SMW and reached it’s peak population (3.8, 3.33 and 3.27 larvae/mrl, respectively) during 37th SMW, while pod borer (0.2 larvae/mrl) was appeared during 33rd SMW and reached it’s peak population (3.4 larvae/mrl) during 38th SMW. The white fly population (0.26 white fly/5 plant) appeared during 31st SMW and attained it’s peak population (12.53 white fly/5 plant) during 36th SMW, while jassid population (0.13 jassid/5 plant) appeared during 31rd SMW and reached it’s peak population (4.8 jassid/5 plant) during 35th SMW. Population of bihar hairy caterpillar, pod borer, spotted pod borer, tobacco caterpillar, white fly and jassid in black gram showed positive correlation with minimum temperature, morning relative humidity and evening relative humidity while negative correlation showed with maximum temperature. Chlorantraniliprole 18.5 SC @ 150 ml/ha was found significantly most effective against bihar hairy caterpillar, pod borer, spotted pod borer and tobacco caterpillar with minimum larval population (1.37 larvae/mrl, 1.43 larvae/mrl, 1.57 larvae/mrl and 0.93 larvae/mrl, respectively). Thiamethoxam 25 WG @ 100 g/ha was found most effective against population of white fly (2.87 white fly/5 plant) and jassid (1.90 jassid/5 plant). Higher seed yield (1206.3 kg/ha), additional yield over control (397 kg/ha) avoidable yield loss (32.89 per cent), additional return (Rs. 22619/ha) and maximum net return (Rs. 17145/ha) was recorded in the treatment of Chlorantraniliprole 18.5 SC @ 150 ml/ha.
