STUDIES ON INCIDENCE AND CONTROL OF Chlumetia transversa Walker (LEPIDOPTERA: NOCTUIDAE) ON MANGO
Incidence of the mango shoot borer, Chlumetia rmnsverra Walkcr was recorded on young grafted nursery plants as well as on three and seven years old mango trees (cv. Dushehari) during 1994 in Paonta valley of Himachal Praclesh. Percentage infestation by the insect varied from 43.3 to 57.7 in young grafted plants and 42.3 to 50 among different aged trees. Cypermethrin (0.005%) provided the highest decrease in the borer incidence in trials of 1994 and 1995, over control followed by fenvalcrate(0.005%). Pruning + monocrotophos 0.05% was an effective integrated treatment which significantly reduced thc pest incidence. Pruning alone as physical treatment failed to give any satisfactory decrease in insect incidence.
