SEASONAL INCIDENCE AND EFFECT OF ABIOTIC FACTORS ON POPULATION DYNAMICS OF ANAR BUTTERFLY (VIRACHOLA ISOCRATES) ON POMEGRANATESenjaliya Tushar M., J.R. Patel, Patel Hiral G. and Dhruv ChaudharyAbstract 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 2nd week of July (28th SMW) to 1st week of August (32nd SMW). The higher activity of anar butterfly was observed during the 3rd week of September (38th 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 3rd week of July (29th SMW) fruit damage per cent was 2.10 and reached up to 36.39 in the 3rd week of September (38th 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. |
