Buffalo treehopper

The buffalo treehopper (Ceresa taurina) is a notorious pest belonging to the family Membracidae within the order Hemiptera. Its common name is derived from the distinct hump-like shape of the pronotum, which resembles the silhouette of a buffalo, and its protective green coloration.

This species is highly polyphagous and infests a wide variety of woody plants. Fruit orchards, particularly those containing apple, pear, and peach trees, are highly susceptible to its activity. Additionally, the pest frequently utilizes various weeds in the undergrowth as primary hosts for its immature stages.

The life cycle of the buffalo treehopper involves a single generation per year. Females use their specialized ovipositors to cut deep slits into the bark of young twigs to lay their eggs, where they successfully overwinter. Nymphs emerge in the spring and typically move to lower vegetation to feed before maturing into adults.

Damage is primarily caused by the mechanical destruction of the bark during the egg-laying process. These deep, U-shaped slits inhibit nutrient and water flow, often leading to the death of small twigs. Severe infestations can significantly stunt the growth of young trees and increase their susceptibility to secondary fungal infections.

• Regular inspection of young trees to identify and prune infested twigs.
• Effective weed management in orchards to eliminate alternative host plants for nymphs.
• Application of targeted insecticides during the nymphal development stage.
• Use of protective measures for young nursery stock to prevent initial colonization.
