ABSTRACT

Investigations were carried out on seasonal incidence of gram pod borer, Helicoverpa
armigera (Hubner) on greengram during kharif, 2008 at College Farm, Junagadh Agricultural
University, Junagadh. The pest appeared with population density of 0.34 larvae per plant during
4th week after sowing (31st standard week) and reached to a peak of 3.42 larvae per plant in 37th
standard week (10th week after sowing). Among the weather parameters, minimum temperature
(r= -0.557) and evening relative humidity (r=-0.583) exhibited highly significant negative
correlation with the gram pod borer population. Rest of the weather parameters were nonsignificantly
correlated with the pest population.
