Seasonal Incidence of Insect Pests of Chickpea in Relation to Abiotic Factors

The present study explored the seasonal incidence of Insect pests of Chickpea in relation to abiotic factors. The field experiment was conducted at Research Farm, Institute of Agricultural Sciences, Bundelkhand University, Jhansi during the Rabi season 2023-2024 to study the seasonal incidence of insect pests of chickpea. The results revealed that the occurrence of the larval population of Helicoverpa armigera starts in the 51st SMW. The peak level was attained in the 3rd SMW. The correlation studies revealed the negative with temperature and relative humidity while the positive correlation was found with rainfall between larval population and abiotic factors. The multiple regression explained the effect of abiotic factors on the larval population. The larval population gradually decreased at 10th SMW. Weather parameters and larval population together were responsible for 39% (R2=0.39) during Rabi season 2023-2024.
