Abstract

A field experiment was carried out at Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (M.S.) during 2012-13. The infestation of aphid, leaf webber and painted bug was initiated during 51st, 2nd and 2nd MW, respectively. The peak incidence of these pests was recorded during 9-10th MW. The correlation between aphid and maximum temperature (r=0.580) was significantly positive. The positively significant correlation was recorded between cabbage bug population and maximum temperature (r=0.810), minimum temperature (r=0.722) and evaporation (r=0.783).
