Due to the importance of cercopids as pests in sugarcane and forage grass, researches have been conducted in order to address aspects related to the bioecology and control of these insects. The objective of this study was to develop a rearing technique for Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) on sugarcane, in the laboratory (25 ± 1ºC; 70 ± 10% RH; and 14-hour photophase). Adults were isolated in cylindrical cages containing one sugarcane plant, with a moistened cotton disc surrounding the base of the plant as a site for oviposition. Eggs were removed from the cotton disc by washing it in running water over sieves and maintained in Petri dishes on moistened filter paper until the nymphs hatched. The newly hatched nymphs were transferred to sugarcane roots and placed into boxes with lids, to keep a moistened and dark environment favoring their development and maintaining the root system, providing food access to the developing nymphs. This method allowed M. fimbriolata to be maintained in laboratory conditions throughout the year, which would certainly foster research on this insect.
