Aspidiotus is a genus of armoured scale insects. [1] It includes several agricultural and horticultural pests.
A. destructor was originally blamed for a massive die-off of coconut trees in the Philippines which began about 2009. It has been involved previously in die-offs in Indonesia. In July 2014, following a detailed morphological review, scientists announced that instead A. rigidus, was to blame. A. rigidus has few natural predators in the Philippines which leads to the surging infestation. [2]
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.
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.
The silverleaf whitefly is one of several species of whitefly that are currently important agricultural pests. A review in 2011 concluded that the silverleaf whitefly is actually a species complex containing at least 40 morphologically indistinguishable species.
Charles Valentine Riley was a British-born American entomologist and artist. He was one of the first individuals to use biological pest control and authored over 2,400 publications. He convinced Congress to create the United States Entomological Commission and was among the founders of the American Association of Economic Entomologists.
Pseudococcus viburni is a close relative of the grape mealybug and a pest of the vineyards around the world.
Coccus is a genus of scale insects in the family Coccidae. Several species, such as Coccus viridis, a major pest of coffee, are major agricultural pests. The type species is Coccus hesperidumLinnaeus.
Encarsia is a large genus of minute parasitic wasps of the family Aphelinidae. The genus is very diverse with currently about 400 described species and worldwide distribution. The number of existing species is expected to be several times higher because many species are still undescribed. Encarsia is a very complex genus, with specimens showing both inter- and intra-specific variations, making morphological classification difficult.
Morganella is a genus of scale insects in the family Diaspididae. Morganella longispina is the type species.
Aulacaspis, is a scale insect genus in the family Diaspididae. The type species is Aulacaspis rosae.
Leucaspidini is a tribe of armored scale insects.
Furcaspidina is a subtribe of armored scale insects, traditionally regarded as part of the Aspidiotini. While the subtribe Furcaspidina was not mentioned in Takagi's 2002 study, the Aspidiotini were not deemed as problematical as the Diaspidini and Lepidosaphidini. In 2006, Williams reduced the Furcaspidina to a single genus, with about twenty-eight species. Andersen in 2009 suggested that the Furcaspidina belonged in an expanded subfamily of Diaspidinae; however, additional analysis suggests that the furcaspids are better placed in a distinct, but laterally equivalent subfamily to the Diaspidinae, possibly together with the gymnaspids which Borchsenius placed in the Aspidiotinae subfamily.
Augulaspidina is a subtribe of armored scale insects. It was not confirmed by Takagi's 2002 study.
Kuwanaspidina is a subtribe of armored scale insects. They feed on bamboo.
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.
Parlatoria is a genus of scales and mealybugs in the family Diaspididae. There are at least 60 described species in Parlatoria.
Cryptognatha nodiceps, known generally as the coconut scale predator or sugarcane scale predator, is a species of lady beetle in the family Coccinellidae; it is found in the Caribbean region, North America, and Oceania, having been introduced to various countries in an attempt to provide biological pest control of the coconut scale.
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 many parts of the world, including Europe.
Aleurodicus cocois, commonly known as the coconut whitefly, is a species of whitefly in the family Aleyrodidae; it feeds on coconut and other palm trees in South America and the Caribbean region.
Chilocorus subindicus, is a species of lady beetle found in India, Sri Lanka and Maldives.
