Abstract:
A field experiment was carried out on seasonal incidence of red pumpkin beetle, Raphidopalpa foveicollis (Lucas) on bottle gourd, Lagenaria siceraria (Molina) Stand. in relation to weather parameters on variety PSPL (Pusa Summer Prolific Long) were conducted at Horticulture farm, S.K.N. College of Agriculture, Jobner during Kharif, 2018. The population of red pumpkin beetle on bottle gourd and leaf damage initiated from the first week of August (32nd SMW) and reached to maximum (5.8 beetles/ plant and 28.6% leaf damage) in the first week of October (40th SMW). The population of red pumpkin beetle had significant positive correlation with maximum temperature (r = 0.575) and significant negative correlation with relative humidity (r = -0.557), while non-significant correlation with minimum temperature and rainfall. The significant positive correlation (r = 0.944) was found between leaf damage of bottle gourd and population of red pumpkin beetle.
