Abstract:
The present investigation was undertaken to observe the seasonal incidence of hairy caterpillar (Euproctis lunata) on apple ber at Dry Land Horticulture Research Farm, Pt. Shiv Kumar Shastri College of Agriculture and Research Station, Surgi, Rajnandgaon during 2021- 22. The studies revealed that the first incidence of hairy caterpillar was recorded during first week of July (27^th SMW) with peak population (4.28 larvae / meter branch) in the last week of September (39^th SMW). The larval population was recorded in the range from 0.06 to 4.28 larvae / meter branch. The population of hairy caterpillar was significantly positively influenced by maximum temperature (r = 0.647), minimum temperature (r = 0.826), average temperature (r = 0.826), morning relative humidity (r = 0.533), evening relative humidity (r = 0.710) and average relative humidity (r = 0.711) however, sunshine (r = -0.343) was significantly negatively influenced the population of the pest.
