Francis Polkinghorne Pascoe
Francis Polkinghorne Pascoe (1 September 1813 – 20 June 1893) was an English entomologist mainly interested in beetles. Biography He was born in Penzance, Cornwall and trained at St. Bartholomew's Hospital, London. Appointed surgeon in the Navy he served on Australian, West Indian and Mediterranean stations. He married a Miss Mary Glasson of Cornwall and settled at Trewhiddle near St Austell where his wife's property produced china clay. Widowed in 1851 he settled in London devoting himself to natural history and entomology in particular. The results of collecting trips to Europe, North Africa and the Lower Amazons were poor and Pascoe worked mainly on insects collected by others. His entomological papers listed and described species collected by Alfred Russel Wallace (in ''Longicornia Malayana''), Robert Templeton and other assiduous collectors but not prolific writers on systematic entomology. He became a Fellow of the Entomological Society in 1854, was president fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Screw Trigonopterus
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigonopterus Oblongus, Lateral Aspect On Thorax Of Weevil (Curculionidae)
''Trigonopterus'' is a genus of flightless weevils placed in the Cryptorhynchinae of Curculionidae. It is distributed in Australia, Indonesia and Melanesia. About 90 species had been formally described until March 2013, when a single paper more than doubled this number, agreeing with previous studies and a systematic barcoding study that many more species have yet to be described. As of October 2021, there were 480 described species. The center of its diversity appears to be New Guinea where 51 or more species can be found in a single locality. Many of them are very similar to each other, but male genital characters and DNA barcoding allow a safe identification. In January 2016, a paper was published that revised the Australian species within this genus. That paper described 24 new species and indicated the potential for more research into undescribed Australian species within this genus. In April 2016, a paper was published that described four new species in this genus from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weevil
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than in length, and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae (the true weevils). It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil (''Stegobium paniceum''), which belongs to the family Ptinidae. Many weevils are considered pests because of their ability to damage and kill crops. The grain or wheat weevil (''Sitophilus granarius'') damages stored grain, as does the maize weevil (''Sitophilus zeamais'') among others. The boll weevil (''Anthonomus grandis'') attacks cotton crops; it lays its eggs inside cotton bolls and the larvae eat their way ou ...

Papua (province)
Papua is a province of Indonesia, comprising the northern coast of Western New Guinea together with island groups in Cenderawasih Bay to the west. It roughly follows the borders of Papuan customary region of Tabi Saireri. It is bordered by the sovereign state of Papua New Guinea to the east, the Pacific Ocean to the north, Cenderawasih Bay to the west, and the provinces of Central Papua and Highland Papua to the south. The province also shares maritime boundaries with Palau in the Pacific. Following the splitting off of twenty regencies to create the three new provinces of Central Papua, Highland Papua, and South Papua on 30 June 2022, the residual province is divided into eight regencies (''kabupaten'') and one city (''kota''), the latter being the provincial capital of Jayapura. The province has a large potential in natural resources, such as gold, nickel, petroleum, etc. Papua, along with four other Papuan provinces, has a higher degree of autonomy level compared to ...

Biological Screw Joint
The biological screw joint is a naturally occurring form of the screw joint, a mechanical device that combines rotational movement with single-axis translation. Alexander Riedel of the State Museum of Natural History Karlsruhe and Thomas van de Kamp of the Karlsruhe Institute of Technology discovered it in specimens of '' Trigonopterus oblongus'', a weevil found in Papua. Discovery Anatomical examination was made for specimens of the weevil species '' Trigonopterus oblongus'', provided by the Karlsruhe State Museum of Natural History, using a microtomograph at the Institute of Synchrotron Radiation (ANKA) of Karlsruhe Institute of Technology. The analysis revealed that the weevils had a nut-and- screw system for the hip- leg joint. Mechanism The mechanism has been described as "rotational movement combined with a single-axis translation". The arthropod hip–leg joint consists of two parts – the coxa (or the hip) and the trochanter (or the head of the arthropod leg fem ...

Beetles Of Asia
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exosk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Of Indonesia
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
