Pheromone lure of Holotrichia consanguinea
White grubs are the white, soft-bodied larvae of several scarab beetle species, including European chafer, Japanese beetle, May/June beetles. They have a brown head and six well-developed legs. When the turf is lifted and grubs are exposed, they tend to be lying on their sides in a C-shaped position. From May through early June, white grubs pupate 2 – 5″ deep in the soil. Adults emerge from pupae a few weeks later. Signs of white grub damage include wilting or yellowing of grass and can result in large patches of dead or crops.
Normally in India, adult beetles emerge from the soil during April-June in response to the first seasonal rains. The adult beetle lays its eggs in the ground during the summer. As the grubs hatch, they start feeding on the roots until cold weather drives them 2 to 8 inches deeper into the soil where they overwinter. When spring arrives, the grubs move up from the lower soil regions and resume feeding near the surface until they become mature and pupate from May through early June.
