Abstract

The incidence of leaf miner, one of the major pests of soybean was noticed during 30th meteorological week (0.10 larvae / plant) on soybean at Parbhani in Maharashtra during 2012-13. The maximum population during the season was observed during 39th MW (2.40 larvae/plant) when the prevailing rainfall, maximum temperature, minimum temperature, before noon relative humidity, afternoon relative humidity, evaporation, bright sunshine hours and wind velocity were 21.8 mm, 32.10C, 21.6 0C, 91 per cent, 58 per cent, 4.3, 7.8 hrs and 3.2 kmph, respectively. The correlation between leaf miner population and maximum temperature (r= 0.687) and evaporation (r=0.807) was found to be positively significant, whereas with minimum temperature (r= - 0.689) and wind velocity (r=-0.754) significant negative correlation was observed. The weather parameters contributed for 99.4 per cent of total variation in the population of leaf miner on soybean.
