Red slug caterpillar, Eterusia magnifica is a major defoliating pest of tea showing recurrence despite synthetic pesticide applications. In PAGE, general esterases were expressed in nine bands designated Est-1 to Est-9. Out of these, in the whole body homogenate Est-8, and in midgut Est-5 bands were absent. In salivary gland homogenate only two bands, Est-3 and Est-4 were detectable.
