Mahanarva fimbriolata (Stål, 1854) - (sugarcane root froghopper)

This froghopper is an important pest of sugarcane in South and Central America. The feeding causes the “burning of sugarcane”, an effect of the toxins in the saliva of the hoppers. It reduces yield and quality of the crop, due to high fibre content and contaminations. In some areas the introduction of green cane harvesting has created more favourable conditions for this pest, because the straw left in the field conserves moisture and protects the diapausing eggs. The old practice of burning the sugarcane before the harvest destroyed most of the eggs.

The nymphs feed on the roots under the straw, causing "froghopper burn" on the leaves. The use of Metarhizium anisopliae as a microbial control method has shown some promise. The total development time of the nymphal stages lasts around 2 months. The eggs might go into diapause. The adult is about 13 mm long.
