Pectinophora
''Pectinophora'' is a genus of moths in the family Gelechiidae. Perhaps the best known species is the pink bollworm, ''Pectinophora gossypiella'' (Saunders). ''P. gossypiella'' is one of the world's most destructive insect pests that causes terrible damage to cotton bolls. The larvae (caterpillars) bore into the bolls, causing them to fall or the blossoms to fail to open. The larvae tunnel through the immature lint and into the seeds eating them. As a result the lint may be unpickable or so stunted as to greatly lower the yield and grade. The yield of oil from the seeds is greatly reduced. Double seeds are found when the cotton is gained, two partly eaten seeds being fastened together. Species Species of this genus include: *'' Pectinophora endema'' Common, 1958 (from Australia) *'' Pectinophora fusculella'' (Pagenstecher, 1900) (from New Guinea) *''Pectinophora gossypiella'' (Saunders 1844) (paleotropical distribution) - pink bollworm *''Pectinophora scutigera ''Pectinophora ...

Pink Bollworm
The pink bollworm (''Pectinophora gossypiella''; es, lagarta rosada) is an insect known for being a pest in cotton farming. The adult is a small, thin, gray moth with fringed wings. The larva is a dull white caterpillar with eight pairs of legs with conspicuous pink banding along its dorsum. The larva reaches one half inch in length. The female moth lays eggs in a cotton boll, and when the larvae emerge from the eggs, they inflict damage through feeding. They chew through the cotton lint to feed on the seeds. Since cotton is used for both fiber and seed oil, the damage is twofold. Their disruption of the protective tissue around the boll is a portal of entry for other insects and fungi. The pink bollworm is native to Asia, but has become an invasive species in most of the world's cotton-growing regions. It reached the cotton belt in the southern United States by the 1920s. It was a major pest in the cotton fields of the southern California deserts. The USDA announced in 2018 that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectinophora Endema
''Pectinophora endema'' is a moth of the family Gelechiidae. It was described by Ian Francis Bell Common in 1958. It is found in Australia, where it has been recorded from Queensland and New South Wales. The larvae have been recorded feeding on the seed capsules of ''Hibiscus'' species, including '' Hibiscus divaricatus'', ''Hibiscus heterophyllus ''Hibiscus heterophyllus'', commonly known as native rosella or toilet paper bush, is a flowering plant in the family Malvaceae. It a shrub or small tree with white, pale pink or yellow flowers with a dark red centre and grows in New South Wale ...'' and '' Hibiscus diversifolius''. Pupation takes place in the fruit of this host plant. The larvae are bright red. References Moths described in 1958 Pexicopiini {{Apatetrinae-stub ...

Pectinophora Scutigera
''Pectinophora scutigera'', the Queensland pink bollworm or pinkspotted bollworm, is a moth of the family Gelechiidae. It was described by Holdaway in 1926 from Australia, where it occurs in coastal and central Queensland. It has also been recorded from Hawaii, New Guinea, Micronesia and New Caledonia.F.W.Willams (1944: 106) Adults are very similar to ''Pectinophora gossypiella'' and can only be separated with certainty by an examination of the genitalia. The larvae feed on ''Gossypium'' species, ''Hibiscus tiliaceus'' and ''Thespesia populnea ''Thespesia populnea'', commonly known as the portia tree (), Pacific rosewood, Indian tulip tree, or milo, among other names, is a species of flowering plant belonging to the mallow family, Malvaceae.

Pectinophora Fusculella
''Pectinophora fusculella'' is a moth of the family Gelechiidae. It was described by Arnold Pagenstecher in 1900. It is found on the Bismarck Archipelago. The wingspan The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan ... is 25–28 mm. The forewings are shining chestnut-brown with ill-defined groups of scales, forming medial and postmedial bands. The hindwings are lighter brown.

Gelechiidae
The Gelechiidae are a family of moths commonly referred to as twirler moths or gelechiid moths. They are the namesake family of the huge and little-studied superfamily Gelechioidea, and the family's taxonomy has been subject to considerable dispute. These are generally very small moths with narrow, fringed wings. The larvae of most species feed internally on various parts of their host plants, sometimes causing galls. Douglas-fir (''Pseudotsuga'') is a host plant common to many species of the family, particularly of the genus '' Chionodes'', which as a result is more diverse in North America than usual for Gelechioidea. By the late 20th century, over 900 genera with altogether more than 4,500 species were placed here, with about 650 genera known from North America alone. While these figures are certainly outdated, due to the many revisions to superfamily Gelechioidea and new descriptions of twirler moths, they still serve to show the enormous biodiversity contained in this ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus '' Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants date ...

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.
