Abstract

An experiment was taken up in the Agro-meteorology field, Central Research Farm of Orissa University of Agriculture and Technology (OUAT), Bhubaneswar during the year 2017-2018 for studying the population build up and population dynamics of Green Leaf Hopper (GLH) and its correlation with different weather parameters viz., temperature (Max. & Min.), RH (Max. & Min.), Rainfall (Max. & Min.) & Sunshine Hours under staggered planting condition with 12 different climatic dates starting from the monsoon period i.e., 16th July 2017 to the winter period i.e., 1st January 2018 at a regular interval of 15 days by involving with three aromatic rice varieties such as Pusa Sugandh –II, Geetanjali and Poorna Bhog. The highest occurrence of the pest was observed during the last week of October and 1st week of November with date of planting on 16th September. So far as the relation of GLH population with different climatic parameters was concerned, GLH was observed with the peak occurrence at temperature (max.) of 32-34°C, temperature (min.) of 24-26°C, high morning relative humidity of 90-95% and 60-95% of evening relative humidity, 2-4 sunshine hours and 40-60 mm rainfall

Keywords

Paddy, Green Leaf Hopper (GLH), Correlation, Climatic parameters, Staggered planting

Conclusion

GLH population was found in almost all the planting dates except 1st January. During last week of October (43 SMW) followed by 2nd week of September (37 SMW),the maximum GLH population was found at a maximum temperature range of 33-35°C, minimum temperature range of 15-27°C with high humidity and sunshine. It was found that, GLH was correlated with all-weather parameters in different dates of planting mainly in positive correlation with relative humidity and rainfall whereas in negative correlation with temperature
