Whiteflies are Hemipterans that typically feed on the undersides of plant leaves. They comprise the family Aleyrodidae, the only family in the superfamily Aleyrodoidea. More than 1550 species have been described.
The Pentatomoidea are a superfamily of insects in the Heteroptera suborder of the Hemiptera order. As Hemiptera, they share a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families. Among these are the shield bugs, giant shield bugs, burrower bugs, and stink bugs.
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 described species.
Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red coloured and are known as red bugs and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name Pyrrhocoris and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli on the top of the head.
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa.
The Mymaridae, commonly known as fairyflies or fairy wasps, are a family of chalcid wasps found in temperate and tropical regions throughout the world. The family contains around 100 genera with 1400 species.
The Margarodidae or ground pearls are a family of scale insects within the superfamily Coccoidea. Members of the family include the Polish cochineal and Armenian cochineal and the original ground pearl genus, Margarodes. Beginning in 1880, a number of distinct subfamilies were recognized, with the giant coccids being the first. Although Maskell proposed a new family, many continued to regard the monophlebids as a mere subfamily for many years, and the Margarodidae classification continued to be polyphyletic through the 20th Century. Since then, taking the advice of Koteja several subfamilies and tribes have been elevated into their own families such as Matsucoccidae and Xylococcidae. The pared-down family of Margarodidae is monophyletic.
Icerya purchasi is a scale insect that feeds on more than 80 families of woody plants, most notably on Citrus and Pittosporum. Originally described in 1878 from specimens collected in New Zealand as pests of kangaroo acacia and named by W.M. Maskell "after the Rev. Dr. Purchas who, [he] believe[d], first found it". It is now found worldwide where citrus crops are grown. The cottony cushion scale originates from Australia.
Paratachardina pseudolobata, the lobate lac scale, is a polyphagous and pestiferous lac scale insect, which damages trees and woody shrubs in Cuba, Florida, the Bahamas and the Australian territory of Christmas Island. It was mistakenly identified as Paratachardina lobata (Chamberlin), an insect native to India and Sri Lanka, but was in 2007 recognized and named as a distinct species based on material from Florida; its native distribution is as yet unknown. The new lac insect was described based on all stages of the female, during the revision of the genus Paratachardina, wherein all its known species were redescribed.
The Tingidae are a family of very small insects in the order Hemiptera that are commonly referred to as lace bugs. This group is distributed worldwide with about 2,000 described species.
Ortheziidae is a family of scale insects commonly known as the ensign scales or ortheziids. They occur in most parts of the world but the majority of the species are found in the Neotropical and Nearctic regions while there are not many species in Australasia and the Far East. There are twenty valid genera and 198 species.
Phenacoleachiidae is a family of scale insects commonly known as the phenacoleachiids. They are found only in the South Island of New Zealand, and on certain offshore islands. There are two species in a single genus.
Putoidae is a family of scale insects commonly known as giant mealybugs or putoids. There is probably a single genus, Puto, containing about sixty species. The genus name Macrocerococcus has also been used but it is now considered to be a synonym of Puto. The genus Puto was formerly classified as a member of the Pseudococcidae; however, it so significantly differed from the rest of the Pseudococcidae that it was accorded its own family Putoidae.
Pinnaspis, first described by Theodore Dru Alison Cockerell in 1892, is a genus of scale insects belonging to the family Diaspididae, or armored scale insects. There are currently 42 species within the genus Pinnaspis.
Phylloxeridae is a small family of plant-parasitic hemipterans closely related to aphids with only 75 described species. This group comprises two subfamilies and 11 genera with one that is fossil. The genus type is Phylloxera. The Phylloxeridae species are usually called Phylloxerans or Phylloxerids.
Callococcus is a genus of Australian scale insect that feeds on species of Leptospermum, Hypocalymma, Kunzea and some other members of the tribes Chamelaucieae and Leptospermeae in the myrtle family Myrtaceae. Callococcus leptospermi induces stem-swelling galls on some species of Leptospermum, and it is considered to be a potential biological control agent of Leptospermum laevigatum in South Africa. The other described species of Callococcus do not induce galls.
Prolepsis is an insect genus of mainly neotropical Diptera in the family Asilidae or robber flies.
Drosicha corpulenta is a species of giant scale insect in the family Monophlebidae, in the superfamily Coccoidea. It is native to eastern Asia where it feeds on a range of trees, shrubs and non-woody plants.
Aspidiotus destructor, the coconut scale, is a species of armoured scale insect in the family Diaspididae, found in many tropical and subtropical parts of the world. It is a serious pest of coconut and banana, and attacks a range of other fruiting trees and ornamental plants.
Callipappus australis, commonly known as the bird of paradise fly, is a species of scale insect in the family Callipappidae. It is native to Australia where it occurs in Queensland and New South Wales.
