Abgrallaspis cyanophylli, the cyanophyllum scale, is one of nine species of the Abgrallaspis genus of armored scale insects. [1] It is a pest throughout the Tropical South Pacific, attacking fruits and ornamental plants. [2]
Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.
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.
A bacteriome is a specialized organ, found mainly in some insects, that hosts endosymbiotic bacteria. Bacteriomes contain specialized cells, called bacteriocytes, that provide nutrients and shelter to the bacteria while protecting the host animal. In exchange, the bacteria provide essentials like vitamins and amino acids to the host insect. Bacteriomes also protect the bacteria from the host's immune system, with insects secreting antimicrobial peptides such as the coleoptericin secreted by weevils to keep bacteria within the bacteriome.
Aonidiella aurantii or red scale is an armored scale insect and a major pest of citrus. It is thought to be a native of South China but has been widely dispersed by the agency of man through the movement of infected plant material. In the United States it is known as California red scale. It was first found in California between 1868 and 1875, apparently brought there on planting material imported from Australia.
Latania lontaroides is a species of palm tree. It is endemic to Réunion. It is also used as an ornamental plant. Its common names include the Red Latan, latanier de la Réunion, and latanier rouge. The armored scale insect Hemiberlesia lataniae was first described from this species of palm, and has since spread around the world and proved to be a serious pest of avocado.
Diaspididae is the largest family of scale insects with over 2650 described species in around 400 genera. As with all scale insects, the female produces a waxy protective scale beneath which it feeds on its host plant. Diaspidid scales are far more substantial than those of most other families, incorporating the exuviae from the first two nymphal instars and sometimes faecal matter and fragments of the host plant. These can be complex and extremely waterproof structures rather resembling a suit of armor. For this reason these insects are commonly referred to as armored scale insects. As it is so robust and firmly attached to the host plant, the scale often persists long after the insect has died.
Albert Koebele was an economic entomologist and a pioneer in the use of biological controls to manage insect pests.
Conchaspididae is a small family of scale insects known as false armoured scales because of their resemblance to Diaspididae.
Aulacaspis yasumatsui, or cycad aulacaspis scale (CAS), is a scale insect species in the genus Aulacaspis that feeds on cycad species such as Cycas revoluta or Dioon purpusii. Other common names include the cycad scale, the sago palm scale, and the Asian cycad scale. This is a serious pest of cycads which can kill its host plant.
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.
Aspidiotini is a tribe of armored scale insects.
Melissotarsus is a rare African genus of ants in the subfamily Myrmicinae. They are known from the Afrotropics and Malagasy regions, where their nests are located in living wood, built by tunneling through the wood under the bark. They are rarely seen outside of their nests, which may contribute to their perceived rarity. However, they are considered pest insects because of damage they can cause to trees, including economically important ones such as mangos and trees in the family Burseraceae, including Aucoumea klaineana, Dacryodes buettneri, and Dacryodes edulis.
Aonidiella is a genus of scale insects in the family Diaspididae, the armored scale insects. Several species are pests of citrus.
Aspidiotus nerii is a species of armored scale insect with the common names Oleander scale and ivy scale.
Aonidiella citrina or yellow scale is an armored scale insect from the family Diaspididae. It feeds by sucking sap from plants in a number of plant families, but is mostly known for being a pest of citrus.
Hemiberlesia lataniae, the latania or palm scale, is a species of armored scale insect in the family Diaspididae. It was first described by the French entomologist Victor Antoine Signoret in 1869 using Latania lontaroides, a species of palm tree endemic to Réunion as its host; since then, it has been found on avocado trees growing in South Africa, Australia, Israel, the United States, and on a range of other plants in many parts of the world.
Chilocorus nigritus, sometimes referred to as the Malaysian ladybird beetle, is a species of lady beetle in the family Coccinellidae. It is native to SE Asia, but has been introduced for use in biological pest control in Hawaii and any parts of the world, including Europe.
Saissetia oleae is a scale insect in the family Coccidae. It is considered one of the three main phytophagous parasites of the olive tree, together with the olive fruit fly and the olive moth. Although it is a common parasite which occurs most often in olive trees, it is a polyphagous species, also attacking citrus trees as well as various ornamental shrubs such as oleanders, pittosporums and euonymus.
Quadraspidiotus juglansregiae, commonly known as the walnut scale, is a species of armoured scale insect in the family Diaspididae. It is native to North America where it feeds on a wide range of ornamental and forest trees and bushes.
Parlatoria blanchardi, the date palm scale, is a species of armored scale insect in the family Diaspididae. It is a widespread and serious pest of palms, both date palms and ornamental species.
