Froghopper

Cercopis intermedia is a species of froghopper belonging to the order Hemiptera and the family Cercopidae. Often referred to simply as a froghopper, this insect is recognized as a specific pest in agricultural environments, impacting the health and development of various herbaceous crops.

The primary host plants for this pest include a range of grasses and legumes. Because these plants are often used for forage and fodder, the presence of Cercopis intermedia can have direct economic consequences for livestock producers and farmers who rely on hay and pasture productivity.

The biology of this insect involves a nymphal stage characterized by the production of "cuckoo spit," a frothy mass that provides insulation and protection against desiccation and predators. Adults are highly mobile insects that move through fields by jumping, which allows them to colonize new plant material efficiently.

Feeding damage occurs when nymphs and adults use their piercing-sucking mouthparts to extract sap from plant tissues. This nutrient loss causes stunting, yellowing, and tissue death. Persistent infestations lead to significant losses in vegetative vigor and reduce the overall quality and nutritional value of the harvest.

Management strategies for controlling Cercopis intermedia focus on a combination of cultural and chemical measures:

• Regular mowing of field margins to reduce the availability of refuge sites.
• Proper soil cultivation practices to disturb the life cycle of the insect in the soil.
• Field scouting during the early development stages to track pest populations.
• Selective insecticide applications based on economic injury thresholds to avoid unnecessary pesticide use.
