Population density of white grubs (Scarabaeidae: Coleoptera) in different crop ecosystem

Author(s):
Sushil Kumar and Ajay Kumar Pandey
Abstract:
Comparative studies on the density of white grub community (Coleoptera: Melolonthidae) occurring in different crop ecosystem fields in Uttarakhand (U.S. Nagar, Nainital and Champawat) and Uttar Pradesh (Bareilly), are presented. Sampling was carried out in different crops during August, October and December, 2019 and 2020. The selected crop was chosen in each locality. The grubs were collected and counted to determine the population density. In the month of August, 2019, the highest mean population of white grub in U.S. Nagar and Bareilly was recorded from sugarcane with 2.92/m2 and 3.00/m2 at 18.30cm and 18.60 cm of soil depth, while in Nainital and Champawat the highest mean population of white grub was observed from the Litchi with 3.80/m2 and 3.13/m2 at 14.60cm and 15.00cm of soil depth, respectively. These results showed that the population density of white grubs increases, and their community composition is affected in cultivated areas.
