Population dynamics of insect pests on black gram was studied in relation with weather parameters... more Population dynamics of insect pests on black gram was studied in relation with weather parameters during pre-kharif 2018 and 2019 in terai region of West Bengal, India. The result revealed that the peak population of whiteflies (7.20/trifoliate/plant) was observed on 14 SMW in 2018, while it was 6.30/trifoliate/plant on 15 SMW in 2019. The peak population of jassids was noticed in 16 SMW in both the year and the population ranged from 4.37 to 4.57/trifoliate/plant. The aphid population started appearing on 8 SMW and increased gradually to reach highest level (24.57/10cm twig/plant and 41.90/10cm twig/plant in 2018 and 2019 respectively) on 10 SMW. The highest larval population of spotted pod borer (1.53/plant and 1.45/plant) and damage (16.07% and 16.29%) to the pod were found during 19 SMW in both the year. Correlation studies indicated that white fly, aphids and spotted pod borer larval population exhibited a significant negative correlation with temperature, relative humidity and...
