The present investigation on effect of abiotic factors on incidence of maize aphids was carried out at Agronomy Farm and Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur. Maize crop was sown in the first fortnight of July, 2017. The population of maize aphids initiated in the first week of August and remained active throughout the growing stage and reached to its peak in the second week of September. The mean aphid population had a significant positive correlation with mean atmospheric temperature (r=0.76); whereas, mean aphid population had non significant negative correlation (r=-0.107) with relative humidity. Mean aphid population had positive but non significant correlation (r=0.065) with rainfall.
