Kakuna (planthopper)

Kakuna is an informal term used in some regions, particularly in certain parts of Africa, to refer to planthoppers. Planthoppers are insects belonging to the infraorder Fulgoromorpha, a diverse group within the order Hemiptera (true bugs). Characterized by their distinctive head shapes and the tendency of many species to "hop" when disturbed, planthoppers feed on plant sap.

They are often mistaken for leafhoppers, but planthoppers have antennae that arise from below the eyes and are often threadlike or bristle-like, while leafhoppers have antennae arising in front of the eyes. The term "Kakuna" is not a scientifically recognized taxonomic designation. When referring to these insects in a scientific context, the term "planthopper" is preferred.

Planthopper species exhibit a wide range of sizes, colors, and morphological features. Some species are significant agricultural pests, transmitting plant diseases or directly damaging crops through feeding. The nymphs of many planthopper species produce waxy secretions that cover their bodies, offering protection from predators and desiccation. Control measures for planthopper infestations vary depending on the specific species and the crop being affected.

While "Kakuna" may be a locally understood name, it is important to use accurate scientific terminology when communicating about these insects outside of its regional context to avoid confusion. Proper identification of planthopper species is crucial for implementing effective pest management strategies.
