STUDIES ON INCIDENCE AND CONTROL OF Chlumetia transversa Walker (LEPIDOPTERA: NOCTUIDAE) ON MANGO

SINGH RAJPAL, THAKUR A. K.

Abstract


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.
