Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
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.
Casuarina, also known as she-oak, Australian pine and native pine, is a genus of flowering plants in the family Casuarinaceae, and is native to Australia, the Indian subcontinent, Southeast Asia, islands of the western Pacific Ocean, and eastern Africa.
Syzygium is a genus of flowering plants that belongs to the myrtle family, Myrtaceae. The genus comprises about 1200 species, and has a native range that extends from Africa and Madagascar through southern Asia east through the Pacific. Its highest levels of diversity occur from Malaysia to northeastern Australia, where many species are very poorly known and many more have not been described taxonomically. One indication of this diversity is in leaf size, ranging from as little as a half inch to as great as 4 ft 11 inches by sixteen inches in Syzygium acre of New Caledonia.
Syzygium smithii is a summer-flowering, winter-fruiting evergreen tree, native to Australia and belonging to the myrtle family Myrtaceae. It shares the common name "lilly pilly" with several other plants.It is planted as shrubs or hedgerows, and features: rough, woody bark; cream and green smooth, waxy leaves; flushes of pink new growth; and white to maroon edible berries. Unpruned, it will grow about 3–5 m (9.8–16.4 ft) tall in the garden.
Syzygium paniculatum, the magenta lilly pilly or magenta cherry, is a species of flowering plant in the myrtle family Myrtaceae, native to New South Wales, Australia. A broad dense bushy rainforest tree, in cultivation it grows to a height of 15 m (49 ft) with a trunk diameter up to 35 cm (14 in). The largest known example is at Ourimbah Creek, 35 m (115 ft) metres tall. The leaves are 3–9 cm (1.2–3.5 in) long, opposite, simple and slightly obovate, tapering at the leaf base. They are dark glossy green above, and paler below. White flowers are produced in clusters. The edible fruit is usually magenta, but can be white, pink or purple. The seeds are polyembryonic.
Pittosporum tenuifolium is a small evergreen tree endemic to New Zealand – up to 10 m (33 ft) – commonly known as kōhūhū and black matipo, and by other Māori names kohukohu and tawhiwhi. Its small, very dark, reddish-purple flowers generally go unnoticed, and are scented only at night. The Latin tenuifolium means "slender-leaved"
Bactericera cockerelli, also known as the potato psyllid, is a species of psyllid native to southern North America. Its range extends from Central America north to the American Pacific Northwest and parts of Manitoba, in Canada. It is restricted to the western part of the continent. As its name suggests, it is commonly found on potato and tomato crops, but has a species range that encompasses over 40 species of solanaceous plants and as many as 20 genera. Breeding hosts are generally recognised as being restricted primarily to Solanaceae, including important crop and common weed species, and a few species of Convolvulaceae, including bindweed and sweet potato. On some plants, especially potato, feeding of the nymphs causes a condition called psyllid yellows, presumed to be the result of a toxin. Both nymphs and adults can transmit the bacterium Candidatus Liberibacter.
Acizzia acaciaebaileyanae is a psyllid common on Acacia baileyana, a popular garden specimen. They have also been associated with Acacia podalyriifolia. The psyllid and its host plant are native to Australia, but both are now widespread where the plant has been introduced including New Zealand, South Africa, Italy, and California, USA. The psyllid can reproduce to very high numbers, but appears not to damage the plant.
Triozidae is one of seven families collectively referred to as jumping plant lice. They have traditionally been considered part of a single family, Psyllidae, but recent classifications divide the group into a total of seven families; most of the genera remain in the Psyllidae, but Triozidae is the third-largest family in the group, containing 27 genera, and a number of pest species.
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.
Syzygium cormiflorum, commonly known as the bumpy satinash, is a species of Syzygium tree endemic to Queensland in northeastern Australia.
Homotomidae is a family of small phloem-feeding bugs in the superfamily Psylloidea, or jumping plantlice.
Trioza is a genus of sap-sucking bugs in the family Triozidae.
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.
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.
Cuspicona simplex, commonly known as the green potato bug, is a herbivorous species of stink bug native to Australia and introduced to New Zealand. It feeds on nightshades. It is primarily known as a pest of potatoes, tomatoes, and other crops in the nightshade family.
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.
Spanioneura fonscolombii, is a species of plant-parasitic psyllid in the family Psyllidae which feed on box. It was first described by Arnold Förster in 1848 and is found in Europe. It is also found in the United States of America where it was accidentally introduced.
