Abstract:
The studies on population built of Chilli aphids during
Kharif season of 2017-18 at the experimental Farm of Department of Agricultural Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani with chilli variety PBNC-1 in non-replicated design was carried out to Status of chilli aphids in Parbhani region and to determine the impact of weather parameters on population built of chilli aphids. A close watch on the incidence of chilli aphids was kept from 32
nd SMW and was continued up to harvest of the crop in 4
th SMW. The population of aphids found to ranged from 1.20 and 9.98 aphids /leaf during 2017-18. During 2017-18 the aphid population was correlated positively significant with the bright sunshine hours (r = 0.711*) and showed negatively significant effect with minimum temperature (r = -0.672*), evening RH (r = -0.773*) and rainfall (r = -0.644*) whereas other wheather parameters were having non Significant correlation with aphids population. regression studies concluded the predictions of the aphid population by using weather parameters were more reliable.
