Onion variety Prasidhi Will be obtained from the Kalash seeds pvt Ltd. The experiment will be laid out in Randomized Block Desigen with three replications. Correlation studies revealed that the onion thrips are non-significant with maximum Temperature (r=0.0204). Correlation studies revealed that the onion Leek moth are significant correlated negative with Maximum Temperature (r=-0.1439), Minimum Temperature (r=-0.4071). Onion maggot are significant correlated negative with Minimum Temperature(r=-0.4204), Average Temperature (r=-0.3011).
