Abstract
The present investigation entitled Study the impact of abiotic factors on the population fluctuation of major insect pest of field pea was conducted at the Experiment field of Department of Plant breeding, seed Breeding farm, JNKVV Jabalpur (MP), Madhya Pradesh during the Rabi season 2020-21. Positive correlation of Acryothosiphon pissum, pod borer, and leafhopper with Maximum Temperature (0.581, 0.581, 0.582) and Acrythosiphon pissum with morning vapour pressure (0.453) may be given due weightage in formulating forewarning modules in the pest. Similarly positive correlation was found between Relative humidity and aphid (r = -0.304) and was found significant. Max temperature showed significant negative correlation (r=-0.581) with aphid, Pod borer and leafhopper’s population where minimum temperature and rainfall showed negative correlation (r=-0.453 and r= - 0.153) with aphid population. Whereas min temperature showed positive non-significant correlation (r= 0.413). Max temperature showed significant negative correlation (r = -0.581) with pod borer population. Morning vapour pressure shows significant negative correlation (r=-0.453) with aphid population.
