Leafhoppers
Scientific names: Mahanarva fimbriolata; Zulia entreriana; Deois flavopicta
Crops: sugar cane and grasses
Damages: Physiological disorder, hindering the flow of water and nutrients. Hollow and thin culms, due to plant phloem and xylem dehydration. Reduction of the photosynthetic capacity due to the injection of toxins and consequent burn of the leaves.
Behavior: the behavior of these insects is directly related to the rainfall regime of each region in the country, starting after the first rains. In the nymph stage, a typical characteristic of this insect is the foam formation at the plant bases, which serves as protection for the nymphs until the adult stage. Adults are more active at night and shelter in the leaf sheaths or cartridges of the plant during the day.
