abstract
The present study was carried out on the seasonal activity of red pumpkin beetle on ridge gourd and weather relation during kharif season of 2017 at Central Experimental Station, Wakawali, Dist. Ratnagiri. The results on seasonal activity revealed that there were marked differences in infestation of red pumpkin beetle. The infestation of red pumpkin beetle (0.84 ± 0.73) was found in the 26^th SMW (25 June - 1 July). The lowest (0.52 ± 0.73) infestation of red pumpkin beetle was recorded in 35^th SMW (27 August – 2 September), while maximum (2.84 ± 0.73) infestation was recorded during 31^st SMW (30 July - 5 August). The data on correlation between mean infestation of red pumpkin beetle with different meteorological parameters showed that the positive correlation with minimum temperature (r= 0.362), while negative correlation with remaining weather parameters viz., maximum temperature, evening relative humidity, Bright Sun Shine Hours and rainfall were found to be non-significant.
