Gelechiid Moth
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 While these figures are certainly outdated, due to the many revisions to superfamily Gelechioidea and new descriptions of twirler moths, they still serve to show the enormous biodiversity contained in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 import ...

Dichomeris Ligulella
The palmerworm (''Dichomeris ligulella'') is a moth of the family Gelechiidae. It is found in eastern North America. 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 of ... is 15–18 mm. Adults are on wing from April to October. There is one generation per year. The larvae feed on apple, hackberry, hazel and oak. The larvae skeletonize leaves and fold or roll them during feeding. It is occasionally responsible for widespread defoliation of hardwood species. Outbreaks rarely last more than one or two years and usually occur during unusually hot and dry springs.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Tecia Solanivora
''Tecia solanivora'', the Central American potato tuberworm, Guatemalan tuber moth, or Guatemalan potato moth, is a moth in the family Gelechiidae. It was described by Povolný in 1973. It is found from Guatemala, through Central America (Costa Rica, El Salvador, Honduras, Nicaragua, Panama) to South America, where it has been recorded from Colombia, Ecuador, Venezuela and Peru. It has also been introduced on the Canary Islands and mainland Spain. The Guatemalan tuber moth, in sufficiently large infestations, can lead to a complete yield loss. Although there is natural variation in the tolerance of potato varieties to feeding by Guatemalan tuber moths, higher tolerance is associated with decreased yield in the absence of infestation. In some potato varieties, notably Pastusa Suprema, infestation of a small number of tubers on each plant can cause uninfested tubers on the infested plants to become larger, leading to increased yield (up to around 20%). Changes in photosynthesis and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sitotroga Cerealella
The Angoumois grain moth (''Sitotroga cerealella'') is a species of the Gelechiidae moth family, commonly referred to as the "rice grain moth". It is most abundant in the temperate or tropical climates of India, China, South Africa, Indonesia, Malaysia, Japan, Egypt and Nigeria, with its location of origin being currently unknown. It is most commonly associated as a pest of field and stored cereal grains as they burrow within the kernel grains of crop plants, rendering them unusable for human consumption. By laying eggs between the grains themselves and hatching at a later time, often during the processing, transportation or storage stages, the moth can be transported to households or countries presently free of Angoumois grain moth infestations. Thus, constant protection against the Angoumois grain moth is required for grain up till the time of consumption. Naming Its common name refers to Angoumois, the pre-revolutionary province of France from which it was first scientificall ...

Phthorimaea Operculella
''Phthorimaea operculella'', also known as the potato tuber moth or tobacco splitworm, is a moth of the family Gelechiidae. It is an oligophagous insect that feeds on the plant family Solanaceae and is especially known for being a major pest of potato crops. Currently farmers utilize insecticides, parasites, and sprinkler irrigation in order to prevent ''P. operculella'' from infesting their croplands. The potato tuber moth also has a rare oviposition process where the ovipositor contains sensors that pick up on chemical signals given off by the host plant. Therefore, the adult female moth only needs to be within the vicinity of a host plant to lay her eggs. Description The potato tuber moth has a body length of about 10mm and a wingspan of about 12mm. Adult moths have a narrow, light brown body with grayish-brown wings containing a variety of small dark spots. The moth contains two sets of wings, both having frayed edges. Females are distinguished from males by having a black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectinophora Gossypiella
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 tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales.

Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fecund
Fecundity is defined in two ways; in human demography, it is the potential for reproduction of a recorded population as opposed to a sole organism, while in population biology, it is considered similar to fertility, the natural capability to produce offspring, measured by the number of gametes (eggs), seed set, or asexual propagules. Superfecundity refers to an organism's ability to store another organism's sperm (after copulation) and fertilize its own eggs from that store after a period of time, essentially making it appear as though fertilization occurred without sperm (i.e. parthenogenesis). Human demography Human demography considers only human fecundity, at its culturally differing rates, while population biology studies all organisms. The term ''fecundity'' in population biology is often used to describe the rate of offspring production after one time step (often annual). In this sense, fecundity may include both birth rates and survival of young to that time step. Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
