Abstract
White grubs or cockchafer beetles are polyphagous soil dwelling pests and Holotrichia consanguinea Blanchard is one of the most damaging infesting agricultural and horticultural crops. A cockchafer beetle trap was devised using anisole (methoxy benzene) as a lure (aggregating pheromone) and was evaluated in an IPM module (30 traps/ ha+ flooding of fields+ weed removal) as recommended by PAU, Ludhiana in guava and grapes orchards in Punjab. The traps were placed at ground level and tied to trunk/vine with approximately 1 trap/ 11 trees in guava and 1 trap/ 55 vines in grapes orchard. In guava, leaf damage was observed to reduced from 36.90% (non-IPM fields) to 8.73% (IPM fields); and in grapes, from 47.75% (non-IPM fields) to 13.15% (IPM fields). It is an eco-friendly technique which can be used at community level to control white grubs in the orchards.
