Cydia Saltitans
''Cydia saltitans'' or jumping bean moth is a moth from Mexico that is most widely known as its larva, where it inhabits the carpels of seeds from several related shrubby trees, mainly '' Sebastiania pavoniana'' or '' Sapium biloculare'' ( syn. ''Pleradenophora bilocularis''). These seeds are commonly known as Mexican jumping beans. The moth lays the egg on the young capsule. The hatched larva gnaws into the fruit, which closes the minute hole during its growth. The larva attaches itself to the capsule with many silken threads by hooks on its anal and four hind abdominal prolegs. When the fruit is warmed, for instance by being held in the palm of the hand, the larva twitches, pulling on the threads and causing the characteristic hop. "Jump" is often an exaggeration, but the beans nonetheless do move around quite a bit. The larva may live for months inside the fruit with periods of inactivity. It eats away the seed inside the capsule, making a hollow for itself. If the fruit i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Codling Moth
The codling moth (''Cydia pomonella'') is a member of the Lepidopteran family Tortricidae. They are major pests to agricultural crops, mainly fruits such as apples and pears. Because the larvae are not able to feed on leaves, they are highly dependent on fruits as a food source and thus have a significant impact on crops. The caterpillars bore into fruit and stop it from growing, which leads to premature ripening. Various means of control, including chemical, biological, and preventive, have been implemented. This moth has a widespread distribution, being found on six continents. Adaptive behavior such as diapause and multiple generations per breeding season have allowed this moth to persist even during years of bad climatic conditions. Geographic distribution Although the geographic origin of codling moths is unclear, there are theories of these moths originating from either Europe or the Mediterranean. Scholars believe that the codling moths were introduced to the Americas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Noctuid Moth
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae. Description Adult: Most noctuid adults have drab wings, but some subfamilies, such as Acronictinae and Agaristinae, are very colorful, especially those from tropical regions (e.g. '' Baorisa hieroglyphica''). They are characterized by a structure in the metathorax called the nodular sclerite or epaulette, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexican Jumping Bean
Mexican jumping beans (also known as ' in Spanish) are seed pods that have been inhabited by the larva of a small moth (''Cydia saltitans'') and are native to Mexico. The "bean" is usually tan to brown. They are from the shrub '' Sebastiania pavoniana'', often also referred to as "jumping bean". However, they are not related to actual beans (legume plants), but rather to spurges. The beans are considered non-toxic but are not generally eaten. In the spring, when the shrub is flowering, moths lay their eggs on the shrub’s hanging seedpods. When the eggs hatch, tiny larvae bore into the immature green pods and begin to devour the seeds. The pods ripen, fall to the ground and separate into three smaller segments, and those segments are called Mexican jumping beans. As the tiny larvae inside curl up and uncurl, they hit the capsule’s wall with their heads – and the bean jumps. It’s been observed that they move more as temperatures rise, the larva eats away the inside of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sebastiania
''Sebastiania'' is a genus of flowering plants in the family Euphorbiaceae first described in 1821. It is native to North and South America from Arizona and the West Indies south to Uruguay.Webster, G. L. & M.J. Huft. 1988. Revised synopsis of Panamanian Euphorbiaceae. Ann. Missouri Bot. Gard. 75(3): 1087–1144 Species Kew's Plants of the World Online accepts 60 species in the genus ''Sebastiania''. Many species formerly included in this genus are now placed in genera such as '' Actinostemon'', '' Bonania'', '' Chrysanthellum'', ''Dendrocousinsia'', ''Ditaxis'', ''Ditrysinia'', '' Gymnanthes'', '' Microstachys'', ''Phyllanthus'', ''Sapium ''Sapium'' is a genus of flowering plants in the family Euphorbiaceae.

Coextinction
Coextinction and cothreatened refer to the phenomena of the loss or decline of a host species resulting in the loss or endangerment of an other species that depends on it, potentially leading to cascading effects across trophic levels. The term originated by the authors Stork and Lyal (1993) and was originally used to explain the extinction of parasitic insects following the loss of their specific hosts. The term is now used to describe the loss of any interacting species, including competition with their counterpart, and specialist herbivores with their food source. Coextinction is especially common when a keystone species goes extinct. Causes The most frequently cited example is that of the extinct passenger pigeon and its parasitic bird lice ''Columbicola extinctus'' and ''Campanulotes defectus''. Recently, ''C. extinctus'' was rediscovered on the band-tailed pigeon, and ''C. defectus'' was found to be a likely case of misidentification of the existing '' Campanulotes flavus''. ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Islands
The Hawaiian Islands ( haw, Nā Mokupuni o Hawai‘i) are an archipelago of eight major islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some from the island of Hawaii in the south to northernmost Kure Atoll. Formerly the group was known to Europeans and Americans as the Sandwich Islands, a name that James Cook chose in honor of the 4th Earl of Sandwich, the then First Lord of the Admiralty. Cook came across the islands by chance when crossing the Pacific Ocean on his Third Voyage in 1778, on board HMS ''Resolution''; he was later killed on the islands on a return visit. The contemporary name of the islands, dating from the 1840s, is derived from the name of the largest island, Hawaii Island. Hawaii sits on the Pacific Plate and is the only U.S. state that is not geographically connected to North America. It is part of the Polynesia subregion of Oceania. The state of Hawaii occupies the archipelago almost in its entirety (includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Weed
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Biological Pest Control
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. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
