Studies on yield loss by grape stem borer Celosterna scabrator Fabr. (Cerambycidae: Coleoptera)

Sunitha ND, Khader Khan H and Giraddi RS

Grape is ravaged by more than 100 insect pests among which stem borer Celosterna scabrator Fabr. (Cerambycidae: Coleoptera) is important and causes significant vine damage and yield loss. An attempt was made to study the yield losses and monitory losses caused by the pest during 2015-16 and 2016-17 in the vine orchards of Vijayapura district (Karnataka: India). Significant difference was recorded between the yield from healthy vines and stem borer affected vines. Pooled statistical analysis of yield data from two seasons of study revealed a significant difference between the yields from healthy vines and borer affected vines. (Z=41.55). Total yield of 425.45 kg/50 vines was recorded from healthy vines whereas stem borer affected vines recorded 186.08 kg. Studies also revealed mean yield loss of 5.05kg/vine, total yield loss of 239.35Kg/50 vines and 3475.75kg/ acre from borer affected vines. Monitory losses occurred to the tune of Rs 101.00/vine, 4787.00/50 vines and 69515.00 /acre.
