Type: article
Abstract: Experiment was carried out on effect of abiotic factors on population dynamics of anar butterfly (V.isocrates) at Horticultural Instructional Farm, S. D. Agricultural University, Sardarkrushinagar during 2020-21.The results revealed that incidence of anar butterfly (V.isocrates) was commenced from 2 nd week of July (28 th SMW) to 1 st week of August (32 nd SMW).The higher activity of anar butterfly was observed during the 3 rd week of September (38 th SMW) at peak activity period of the pest in Mrig bahar.Thereafter the larva of anar butterfly was decreased at 5.63 to 1.83 per cent.In the 3 rd week of July (29 th SMW) fruit damage per cent was 2.10 and reached up to 36.39 in the 3 rd week of September (38 th SMW).The corrected fruit damage per cent was found to be negatively non-significant during experiment, whereas bright sunshine (r = 0.181) and morning relative humidity (r = 0.047) was a positive non-significant.Two weather parameters wind speed (r = -0.719**)and maximum temperature (r = -0.566*)had highly significant negative and significant negative association with fruit damage caused by V. isocrates.Minimum temperature, evening relative humidity and rainy days showed negative non-significant correlation with fruit damage (r= -0.327, r= -0.041 and r= -0.121) respectively.
