Abstract:
The investigations on “Population dynamics of red and black pumpkin beetle, Aulacophora foveicollis Lucas on cucumber, Cucumis sativus Linneaus” was carried out at College Farm, College of Agriculture, Navsari Agricultural University, Bharuch (Gujarat) during summer, 2020. The population of red pumpkin beetle, A. foveicollis on cucumber initiated from 3rd week of March (11th SMW, 4th WAS) and persisted till 4th week of May (21th SMW, 14th WAS) in the range of 0.13 to 3.30 beetles/plant with an average of 1.49 beetle/plant. The population reached to the first (2.53 beetles/plant) and second as well as the highest (3.30 beetles/plant) peak during 2nd week of April (15th SMW, 8th WAS) and 1st week of May (18th SMW, 11th WAS), respectively. The correlation studies revealed that bright sunshine hours (r= 0.64906*) and evapotranspiration rate (r= 0.66310*) significantly positively correlated while, maximum temperature (r= 0.72768**) and wind speed (r= 0.79715**) showed highly significant and positively associated with the activity of red pumpkin beetle. The other weather parameters had non-significant association with red pumpkin beetle population.
