abstract
Field experiment was carried out to study the seasonal incidence of major pod borers (Etiella zinckenella Treitschke and Helicoverpa armigera Hubner) on vegetable pea and its relation with abiotic factors under natural conditions at the old campus, SVP University of agriculture and technology, Meerut (U.P.). During the observation the population of E. zinckenella larval reached its peak (12.66 larvae/10 plants) in the all control plots on 26^th February (8^th standard weeks) when the maximum and minimum temperature 22.07°C and 12.55°C, respectively, relative humidity 81.07% and rainfall 11.72 mm was recorded. The larval population of E. zinckenella showed negative correlation with maximum temperature (r= -0.007) while positively correlated with minimum temperature (r= 0.378) and the correlation between larval population and relative humidity was found positive (r= 0.313) and also positive with rainfall (r= 0.393). The observation on the population of H. armigera larval reached its peak (10.33 larvae/10 plants) in all control plots on 26^th February (8^th standard weeks) when the maximum and minimum temperature 22.07°C and 12.55°C, respectively, relative humidity 81.07% and rainfall 11.72 mm was recorded. The larval population of H. armigera showed negative correlation with maximum temperature (r= -0.034) while minimum temperature (r= 0.364), relative humidity (r= 0.351) and rainfall (r= 0.384) were positively correlated during crop season i.e. Rabi 2014-15.
