Abstract:
The field experiments entitled “Seasonal incidence of gram pod borer, Helicoverpa armigera Hubner relation to abiotic factors in chickpea, Cicer arietinum L.” was carried out at Students’ Instructional Farm of C. S. Azad University of Agriculture & Technology, Kanpur during Rabi 2017-18 and 2018-19. The initial incidence of larval population was observed 1.67 and 1.33 larvae/5 plants during the 49th and 50th SW, respectively. The population increased gradually and reached its peak on 6th and 7th SW with 12.67 and 11.67 larvae/5 plants, respectively. The correlation matrix for both years indicated negatively correlation with minimum r= -0.403 and r=-0.173 and maximum temperature r=-0.440 and r=-0.531 with larval population. However, positive correlation with relative humidity r=0.498 and 0.579 and rainfall 0.231 and 0.489, respectively.
