A new effcient light trap has been designed, fabricated and tested for trapping effciency against scarab beetles. In feld testing, out of the total beetles trapped, 29.96 percent were trapped by the M-3 model followed by that were M-5 (24.56%), M-2 (19.68%), M-4 (16.50%) and M-1 (9.27%) models. Compact fluorescent lamp was found most effective light source in trapping the scarab beetles. The most effcient model of the trap was also tested for its trapping effciency against different group of insects, which included Scarabaeidae (56.74 to 64.73%), Coleoptera except Scarabaeidae (8.51 to 14.88%), Lepidoptera (10.63 to 12.38%), Diptera (2.85 to 10.70%), Hemiptera (1.43 to 2.04%), Dermaptera (0.00 to 0.54%), Orthoptera (0.34 to 1.45%), Isoptera (1.65 to 7.92%) and the Hymenoptera (0.34 to 0.65%). The trap is specifc to scarabaeids to a great extent. The low cost, effcient user-friendly trap is becoming exceptionally popular amongst the farmers and holds promise in containing the white grub problem in the Himalayan region.
