Author(s): NE Jayewar, BV Bhede and BB Bhosle

Abstract: The investigation was carried out to determine the impact of weather parameters on seasonal incidence of chilli aphids during Kharif season of 2016-17 at the experimental Farm of Department of Agricultural Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani with chilli variety PBNC-1 in non-replicated design. Seasonal Incidence studies where intiated from 32 nd SMW and observation on incidence were continued up to harvest of the crop in 4th SMW. Ahids infestation was intiated during 44th SMW (2.00 aphids/leaf) and it was continued to increase and reached its peak 11.56 aphids/ leaf in 50th SMW. During 2016- 17 Correlation studies revealed that, the correlation of aphid population showed positively significant correlation with the bright sunshine hours and negatively significant effect with minimum temperature, morning RH, evening RH, wind velocity and rainfall.
