International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
demonstrated for the management of white grub beetle by installing VL White Grub Beetle
Trap -1 at NICRA adopted village Karalapalari of KVK Bageshwar under TDC-National
Innovations of Climate Resilient Agriculture (TDC- NICRA) project. Karalapalari is located
in Kafligair Tehsil, 35 km away from district head quarter Bageshwar, Uttarakhand. In this
village 64 households are present and the village is having 45.61 ha total geographical area and
20.05 ha rainfed cultivated area.
Methodology
Before NICRA project intervention the farmers of this village were mostly unaware about the
life cycle and management of the white grub. Therefore, awareness programme for the farmers
were conducted to adopt VL White Grub Beetle Trap -1. The light traps were installed at
strategic locations for the management of white grub beetles in village Karalapaladi. Data
collection for the trapped white grub beetles was done at weekly interval for five months
starting from June 2022 till October 2022 with the participation of farmers.
Results
Very encouraging results were found and 1.32 lakh beetle were trapped between June to Oct
2022 in the first year of installation of VL White Grub Beetle Trap -1. The data also showed
that maximum trapping of white grub beetles was concentrated from second week of July to
third week of August. While in first week of June and last week of October, it was the
minimum. It is projected that this trapping of beetles will consequently result in 80-90%
reduction in grub population. This huge reduction in beetle and grub population will ultimately
improve the rainfed agro- ecosystem in a sustainable manner.

Rice (Oryza sativa L.) is one of the major staple food grains for more than 50% of the world’s
population. The option of intensifying the area under rice in the near future is limited. The
major challenge is to achieve this gain with less water, labor, and chemicals, thereby ensuring
long-term sustainability. Depending on water and labor paucity, farmers are altering either their
rice establishment methods from transplanting to direct seeding in unpuddled soil with
adopting DSR, it is possible to save water. Among the cultural technologies, planting density
is one of the important components, the manipulation of which is an essence for optimizing
Managing genetic resources for enhanced stress tolerance
