ABSTRACT

Studies on the population dynamics of aphid, Lipaphis erysimi (Kaltenbach) on mustard
revealed that the pest was active from November to February (flowering stage to harvest of the
crop) and ranged between 0.43 and 4.67 aphid index/ plant. The pest population exhibited
highly significant negative correlation with maximum temperature and minimum temperature.
Evening relative humidity and sunshine hours were also negatively correlated. whereas, morning
relative humidity showed significant negative correlation. On the other hand, wind velocity
exhibited highly significant positive correlation with the pest.
