Anchylorhynchus
''Anchylorhynchus'' is a genus of weevils belonging the family Curculionidae and subfamily Curculioninae. It currently includes 25 described species distributed from Panama to Argentina. Members of the genus are pollinators of palms in the genera '' Syagrus'', ''Oenocarpus'' and ''Butia'', with adults living in inflorescences and larvae feeding on developing fruits. The first instar larvae of ''Anchylorhynchus'' have an unusual morphology, being specialized on killing other larvae infesting the palm fruits. Adult morphology ''Anchylorhynchus'' can be readily distinguished from other Derelomini by a number of features. The body is round, convex, and densely covered by scales varying from yellow to black. The rostrum is flattened dorso-verntrally at the apex, and exhibits 2-7 longitudinal grooves from the base of the rostrum to the insertion of antennae. The antennal funicle (segments excluding the first and the club) has only six segments, as opposed to seven segments in other ...

Curculioninae
The beetle subfamily Curculioninae is part of the weevil family Curculionidae. It contains over 23,500 described species in 2,200 genera, and is therefore the largest weevil subfamily. Given that the beetle order (Coleoptera) contains about one-quarter of all known organisms, the Curculioninae represent one of the – if not ''the'' – most successful radiations of terrestrial Metazoa. Many weevils of this group are commonly known as flower weevils or acorn and nut weevils, after a food commonly eaten by Curculioninae larvae and imagines — the reproductive organs of plants. Systematics This large subfamily is divided into around 30 tribes. Delimitation of the Curculioninae is fairly robust considering its enormous size; there is some dispute, however, in their exact boundary with the Molytinae. The Phrynixini and Trypetidini are also included in the Curculioninae by some authors, but more often they are considered Molytinae; conversely, the Itini are usuall ...

Carl Johan Schönherr
Carl Johan Schönherr (10 June 1772 – 28 March 1848) was a Swedish entomologist who revised the taxonomy of beetles, including weevils. Born in Stockholm, Schönherr was son of a German immigrant who had established himself as a silk manufacturer. At the age of nineteen, he took over the business together with his mother and developed it into a considerable size, with about 200 workers. In 1805, he entered partnership with Erik Lundgren, and in 1811 he sold the business to him, while retiring to his manor Sparresäter in Lerdala outside Skara in Västergötland, where he died in 1848. Schönherr had taken an interest in entomology since the age of twelve and was later further stimulated through his friendship with Gustaf Johan Billberg, his brother-in-law from his second marriage.Bengt Ehnström, "Schönherr, Carl Johan", ''Svenskt biografiskt lexikon'', vol. 31, p. 755. He was an eminent coleopterist co-operating with Carl Henrik Boheman and Leonard Gyllenhaal. Schönherr w ...

Syagrus Coronata
''Syagrus coronata'', commonly known as the ouricury palm, aricuri palm, or licuri palm, is a species of palm tree that is native to eastern Brazil, ranging from the southern part of the state of Pernambuco, into the state of Bahia, south to the Jequitinhonha River in the state of Minas Gerais. The tree can live for 30-150 years, though most only live for 8-10 years on average. It plays an important role in the diets of tropical seasonally dry forest animals. Description ''Syagrus coronata'' reaches tall with a crown of semi-plumose leaves. The blooms are bright yellow, and the plants bear fruit for most of the year. Ecological importance Licuri palm nuts are the main food source of Lear's macaw, making up around 95% of their diet. These nuts can grow to be one inch (2.5 cm) in width. Threats The destruction of small seedlings by cattle poses a threat to the plants, primarily through the destruction of concentrated groves. Those groves are vital to Lear's macaw. Uses '' ...

Gregório Bondar
Gregório Gregorievitch Bondar (1881 – 1959) was a Ukrainian-Brazilian agronomist and entomologist that greatly contributed to Brazilian Entomology. In honor of his contributions, an agricultural research station was created in Belmonte, Bahia and named after him. Biography Early life Bondar was born to a family of farmers who owned 5 hectares of land in the village of Malaia Buromca, district of Zolotonosha. There he attended elementary school, graduating in 1892. In 1894, his family emigrated to the department of Yeniseysk, in Siberia. There he has worked for a year as a farmer, being later appointed as a clerk for the municipality. In 1896, he moved to Kansk, where he worked as a clerk at the police department. In 1899, he quit his job and went back to school in Krasnoyarsk, graduating in 1902. Between 1902 and 1905, he worked as Elementary School teacher in Yeniseysk. Imprisonment and first migration to Brazil In 1905, Bondar was drafted by the military to fight in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Entomological Society Of Stettin
The Entomological Society of Stettin (german: Entomologischer Verein zu Stettin) or Stettin Entomological Society, based in Stettin (Szczecin), was one of the leading entomological societies of the 19th century. Most German entomologists were members, as were many from England, Sweden, Italy, France, and Spain. The society had very large collections and a very comprehensive library. This first German entomological society was formed in 1839. Following the death at age 39 of its first and short-lived president, Dr. Wilhelm Ludwig Ewald Schmidt, Carl August Dohrn (1806-1892), a lifelong resident of the then Prussian town of Stettin, became its second president. He was elected at an anniversary meeting on 5 November 1843. Having acted as secretary of the society for the previous four years, he continued in this role, and that of president, for the next forty. Under Dohrn's presidency the society became as important as the entomological societies of London and Paris. As in these count ...

Euterpe Edulis
''Euterpe edulis'', commonly known as juçara, jussara (an archaic alternative spelling), açaí-do-sul or palmiteiro, is a palm species in the genus '' Euterpe''. It is now predominantly used for hearts of palm. It is closely related to the açaí palm, the açaí palm has differences though ('' Euterpe oleracea''), a species cultivated for its fruit and superior hearts of palm. The larvae of '' Caligo brasiliensis'' are reported to feed on ''E. edulis''. Although it was formerly widely harvested in Brazil for hearts of palm, it is now uncommon in the wild and no longer harvested commercially due to past over harvesting.This endangering of the species could cause it to fall extinct.

Oviposition In Anchylorhynchus Eriospathae
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ti ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cannibal Weevil Larva
Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. Human cannibalism is well documented, both in ancient and in recent times. The rate of cannibalism increases in nutritionally poor environments as individuals turn to members of their own species as an additional food source.Elgar, M.A. & Crespi, B.J. (1992) ''Cannibalism: ecology and evolution among diverse taxa'', Oxford University Press, Oxford ngland New York. Cannibalism regulates population numbers, whereby resources such as food, shelter and territory become more readily available with the decrease of potential competition. Although it may benefit the individual, it has been shown that the presence of cannibalism decreases the expected survival rate of the whole population and increases the risk of consuming a relative. Other negative effects may include the increased ri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Insect Morphology
Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata) (head, thorax, and abdomen), have three pairs of legs, and mouthparts located ''outside'' of the head capsule. It is this position of the mouthparts which divides them from their closest relatives, the non-insect hexapods, which includes Protura, Diplura, and Collembola. There is enormous variation in body structure amongst insect species. Individuals can range from 0.3 mm (fairyflies) to 30 cm across ( great owlet moth); have no eyes or many; well-developed wings or none; and legs modified for running, jumping, swimming, or even digging. These modifications allow insects to occupy almost every ecological niche on the planet, except the deep ...

Metathorax
The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs. Its principal sclerites ( exoskeletal plates) are the metanotum (dorsal), the metasternum (ventral), and the metapleuron (lateral) on each side. The metathorax is the segment that bears the hindwings in most winged insects, though sometimes these may be reduced or modified, as in the flies (Diptera), in which they are reduced to form halteres, or flightless, as in beetles (Coleoptera), in which they may be completely absent even though forewings are still present. All adult insects possess legs on the metathorax. In most groups of insects, the metanotum is reduced relative to the mesonotum. In the suborder Apocrita of the Hymenoptera, the first abdominal segment is fused to the metathorax, and is then called the propodeum.
