Psyllidae, the jumping plant lice or psyllids, are a family of small plant-feeding insects that tend to be very host-specific, i.e. each plant-louse species only feeds on one plant species (monophagous) or feeds on a few closely related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies, they form the group called Sternorrhyncha, which is considered to be the most "primitive" group within the true bugs (Hemiptera). They have traditionally been considered a single family, Psyllidae, but recent classifications divide the group into a total of seven families; the present restricted definition still includes more than 70 genera in the Psyllidae. Psyllid fossils have been found from the Early Permian before the flowering plants evolved. The explosive diversification of the flowering plants in the Cretaceous was paralleled by a massive diversification of associated insects, and many of the morphological and metabolic characters that the flowering plants exhibit may have evolved as defenses against herbivorous insects.
The genus Orius consists of omnivorous bugs in the family Anthocoridae. Adults are 2–5 mm long and feed mostly on smaller insects, larva and eggs, such as spider mites, thrips, jumping plant lice, and white fly, but will also feed on pollen and vascular sap.
Psylloidea is a superfamily of true bugs, including the jumping plant lice and others which have recently been classified as distinct families. Though the group first appeared during the Early Jurassic, modern members of the group do not appear until the Eocene, and Mesozoic members of the order are usually assigned to the possibly paraphyletic family Liadopsyllidae.
Psylla pyri, commonly known as the pear psylla or pear psyllid, is an insect in the family Psyllidae. Originating in Europe and Asia, it has spread to North America. It is a pest of pear trees, sucking the sap, damaging the foliage, flowers and fruit and diminishing the crop.
Aacanthocnema is a genus of bugs from the jumping plant lice family (Triozidae). The genus is endemic to Australia, and currently contains six species, found in all states and territories with the exception of the Northern Territory.
Trioza erytreae, the African citrus psyllid, is a sap-sucking insect, a hemipteran bug in the family Triozidae. It is an important pest of citrus, being one of only two known vectors of the serious citrus disease, huanglongbing or citrus greening disease. It is widely distributed in Africa. The other vector is the Asian citrus psyllid, Diaphorina citri.
Psylla is a genus of sap-sucking insects belonging to the order Hemiptera. There are at least 110 described species in Psylla. Species within the genus feed on various host plants.
Trioza is a genus of sap-sucking bugs in the family Triozidae.
Anthocoris nemoralis is a true bug in the family Anthocoridae. The species is native to Europe and is introduced in North America. It is a predator of aphids, spider mites and jumping plant lice, and is therefore used as a biological pest control agent.
Psylla buxi, known generally as the boxwood psyllid or box sucker, is a species of plant-parasitic hemipteran in the family Psyllidae. It is native to Europe and introduced to North America.
Psyllinae is a subfamily of plant-parasitic hemipterans in the family Psyllidae. There are about 12 genera and at least 40 described species in Psyllinae.
Psylla carpinicola is a species of plant-parasitic hemipteran in the family Psyllidae.
Trioza centranthi is a sap-sucking hemipteran bug in the family Triozidae which creates galls on the leaves and flowers of Centranthus and Valerianella species. It was first described by Jean Nicolas Vallot, a French entomologist in 1829 and is found in Europe.
Trioza remota is a sap-sucking hemipteran bug in the family Triozidae which creates galls on the leaves of oak.
Trioza adventicia, commonly known as the syzygium leaf psyllid, lillypilly psyllid, or eugenia psyllid, is a sap-sucking hemipteran bug in the family Triozidae which creates galls on the leaves of Syzygium paniculatum. This species is native to eastern Australia and has been introduced into California, southern Australia, and New Zealand.
Psylla alni is a species of psyllid, a plant-feeding hemipteran in the family Psyllidae.
Trioza alacris is a sap-sucking hemipteran bug in the family Triozidae which creates galls on the leaves of Laurus species. It is found in Europe.
Baeoalitriozus is a genus of true bugs belonging to the family Triozidae. The species of this genus are found in Northern America, Africa and Southeastern Asia.
Psylla frodobagginsi or the hobbit kōwhai psyllid is a species of psyllid, a plant-feeding hemipteran in the family Psyllidae. It is endemic to New Zealand and is found only on New Zealand kōwhai trees and is named after the character Frodo Baggins from The Lord of the Rings.
