abstract
The present research work was carried out at the department of Entomology, College of Agriculture, J.N.K.V.V, Jabalpur during rabi session 2016-17. Correlation between Aphis craccivora population with maximum temperature was non-significant (r= 0.332). Similarly no correlation was observed between its population and minimum temperature (r =0.114). Population of Aphis craccivora indicated positive correlation with morning relative humidity (r = 0.685) and the regression equation was y = 2.776 x – 221.9. Population of Aphis craccivora did not show any correlation with evening relative humidity. Population of Acyrthosiphon pisum indicated significant positive correlation with morning relative humidity, with r value of 0.768 and the regression equation obtained was y = 0.205x-16.40. Its population did not show any correlation with evening relative humidity (r = -0.06). Population of H. armigera was very low during the crop season. Its population did not show significant correlation (r = -0.45) with maximum temperature and minimum temperature (r = 0.217).
