plant lice, psyllids, jumping plant-lice

Subfamily Guides

is a of plant-parasitic hemipterans commonly known as plant lice or jumping plant-. The family comprises more than 20 and approximately 370 described worldwide. Members are characterized by their ability to jump and their association with vascular plants as phloem-feeders. The family includes significant agricultural pests, most notably Diaphorina citri (Asian citrus psyllid), the primary of (Huanglongbing). Liviidae was formerly treated as Triozidae, and recent taxonomic revisions recognize three monophyletic : Euphyllurinae, Liviinae, and the Neophyllurinae.

Distribution

Worldwide distribution with recorded across multiple continents including the Americas, Europe, Africa, and Asia. Specific distribution records include Belgium (Livia crefeldensis), Brazil (Paurocephalini tribe), and Panama (Diaphorina citri in citrus production areas).

Ecological Role

Members of function as phloem-feeding herbivores on vascular plants. Several serve as of plant , with Diaphorina citri being the most economically significant as the primary vector of Candidatus Liberibacter asiaticus, the bacterium causing (Huanglongbing). The contributes to plant-insect and serves as prey for various natural enemies including (Tamarixia radiata, Diaphorencyrtus aligarhensis), ladybird beetles, lacewings, and spiders.

Human Relevance

includes major agricultural pests with substantial economic impact. Diaphorina citri (Asian citrus psyllid) is the most serious threat to global citrus production, vectoring a that has caused billions of dollars in losses and the destruction of thousands of hectares of citrus orchards. Management strategies include chemical control, using imported , attract-and-kill devices, trap cropping, and mesh-covered monitoring traps to reduce bycatch. Other such as Euphyllura olivina (olive psyllid) also impact crop production.
