Agarwal, R.A. 1969 Morphological characteristics of sugarcane and insect resistance.. Entomologia Experimentalis et Applicata 12: 767-776.

Notes: Physiological, chemical and morphological make-up of the different sugarcane clones have a great impact on resistance to various insect pests. A low number of stomata per unit has been associated with the resistance character of varieties to sugarcane scale (Melanaspis glomerata).
