Abstract (AB)	The scale insect Aulacaspis tegalensis is a chronic pest of sugar cane in the drier regions of Mauritius. Severe infestations by this insect can cause up to 34 per cent reduction in IRSC. Control of this pest relies on cultural practices such as cane trashing which favours the development of natural enemies. Sugarcane varieties with tightly clinging leaf sheaths (e.g. R 570) have been found to harbour a high population of the insect. A laboratory study was carried to assess the role of other sugar cane morphological characters on the behaviour of crawlers. Varieties M 1658/78, M 695/69, M 1176/77, M 555/60, S 17and R 570 were studied. It was found that bud groove and root band characteristics favour the settling of young crawlers, while waxy internodes are unfavourable. Together with leaf sheath tightness, these characters can be used as criteria for selecting cane varieties unlikely to favour the development of scale insect.
