ABSTRACT
Effect of abiotic factors on the seasonal incidence of major insect pests was observed on okra crop during kharif 2011. The incidence of jassids showed positive correlation between various abiotic factors sunshine. However, viz., minimum temperature, evening relative humidity (RH), wind velocity and no of rainy days exhibited significant negative correlation and maximum temperature, morning RH and rainfall exhibited non-significant. Non-significant correlation were recorded for abiotic factors with incidence of whitefly while minimum temperature, evening RH, wind velocity, rainfall and no. of rainy days showed negative correlation with shoot and fruit borer population and found negative significant. Sunshine showed positive correlation with shoot and fruit borer population and found positive significant. The statistically significant values indicated that occurrence of insect pests population was due to the prevailing ecological conditions. Thus the management of okra pest complex during kharif sown okra should therefore be promoted and tailored from September onwards using an integrated approach.
