Velayudhan, K.C., & Liji, R.S. 2003 Preliminary screening of indigenous collections of turmeric against shoot borer (Conogethes punctiferalis Guen.) and scale insect (Aspidiella hartii Sign.).. Journal of Spices & Aromatic Crops 12(1): 72-76.

Notes: The incidence of shoot borer (C. punctiferalis) and scale insect (Aspidiella hartii) on the indigenous collection of 489 turmeric accessions under field epiphytotic conditions at Vellanikkara, Thrissur, Kerala, India during the 2001 cropping season was determined. The collections belonged to 21 morphotypic groups of turmeric from different agroclimatic conditions in India. The lowest incidence of shoot borer (mean score 2) was observed in morphotype 2 followed by 2.6 in morphotype 14. The lowest scale insect incidence of 0.5 was scored in morphotype 6. Eighty accessions were free of scale insect but were susceptible to shoot borer. The highest susceptibility to the scale insect was recorded by accessions IC 137023 and IC 88895. A total of 22 accessions were tolerant to shoot borer with <3 score.
