Euops Tibialis
''Euops'' is a genus of the leaf-rolling weevils (family Attelabidae) containing more than 300 species. It is spread over most tropical and subtropical regions but is missing from America. The centre of its radiation is New Guinea and Australia where it is the only representative of the subfamily Attelabinae. Females of ''Euops'' have mycangia in the space between metathorax and abdomen. Leaf rolls prepared for oviposition are inoculated with spores from these mycangia. Moreover, the leaf-rolls are treated by the female using abdominal setose brushes that in most species apply secretions of unknown function. The fungus growing on a thus treated leaf-roll does not improve its nutritional value but may play a role as an antagonist of other microbes potentially harmful to the weevil larva A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Johan Schönherr
Carl Johan Schönherr (10 June 1772 – 28 March 1848) was a Swedish people, Swedish entomologist who revised the Taxonomy (biology), taxonomy of beetles, including weevils by examining all the descriptions of beetles since the time of Linnaeus. He began with an examination of the Charles De Geer, Charles de Geer collection which had been handed to the Swedish Academy of Sciences in 1778. He introduced the system of using a red label to mark historical specimens that had served as the basis of De Geer's descriptions. This continues to be a standard practice in entomological collections today for Holotype, holotypes. Life and work 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. Schönherr had taken an interest in entomology, a contemporary trend inspired by Emanuel Swedenborg, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attelabidae
The Attelabidae is a widespread family of weevils. They are among the primitive weevils, because of their straight antennae, which are inserted near the base of the rostrum. The prothorax is much narrower than the base of the elytra on the abdomen. Attelabidae and the related family Rhynchitidae are known commonly as the leaf-rolling weevils.Legalov, A. A. (2004)New data of the leaf-rolling weevils (Coleoptera: Rhynchitidae, Attelabidae) of the world fauna with description of 35 new taxons.''Baltic Journal of Coleopterology'' 4(1) 63-88. Rhynchitidae may be treated as subfamily Rhynchitinae of the Attelabidae. Some members of this family have long necks and may be called giraffe weevils, particularly '' Trachelophorus giraffa''. A few species are minor agricultural pests. The larvae of Rhynchitinae feed in flower buds, fruits, and terminal shoots, or are leaf miners. The subfamily Attelabinae are the true leaf rollers. The female cuts slits into leaves to deposit her eggs, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Mainland Australia, Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the perceived resemblance of the indigenous peoples of the island to those in the Guinea (region), African region of Guinea. The eastern half of the island is the major land mass of the nation of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doctor Of Philosophy
A Doctor of Philosophy (PhD, DPhil; or ) is a terminal degree that usually denotes the highest level of academic achievement in a given discipline and is awarded following a course of Postgraduate education, graduate study and original research. The name of the degree is most often abbreviated PhD (or, at times, as Ph.D. in North American English, North America), pronounced as three separate letters ( ). The University of Oxford uses the alternative abbreviation "DPhil". PhDs are awarded for programs across the whole breadth of academic fields. Since it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and, in some cases, defend their work before a panel of other experts in the field. In many fields, the completion of a PhD is typically required for employment as a university professor, researcher, or scientist. Definition In the context o ...

Ludwig Maximilian University Of Munich
The Ludwig Maximilian University of Munich (simply University of Munich, LMU or LMU Munich; ) is a public university, public research university in Munich, Bavaria, Germany. Originally established as the University of Ingolstadt in 1472 by Duke Ludwig IX of Bavaria-Landshut, it is Germany's List of universities in Germany, sixth-oldest university in continuous operation. In 1800, the university was moved from Ingolstadt to Landshut by King Maximilian I Joseph of Bavaria when the city was threatened by the French, before being transferred to its present-day location in Munich in 1826 by King Ludwig I of Bavaria. In 1802, the university was officially named Ludwig-Maximilians-Universität by King Maximilian I of Bavaria in honor of himself and Ludwig IX. LMU is currently the second-largest university in Germany in terms of student population; in the 2023/24 winter semester, the university had a total of 52,972 matriculated students. Of these, 10,138 were freshmen, while internati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycangium
The term mycangium (pl., mycangia) is used in biology for special structures on the body of an animal that are adapted for the transport of symbiotic fungi (usually in spore form). This is seen in many xylophagous insects (e.g. horntails and bark beetles), which apparently derive much of their nutrition from the digestion of various fungi that are growing amidst the wood fibers. In some cases, as in ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae), the fungi are the sole food, and the excavations in the wood are simply to make a suitable microenvironment for the fungus to grow. In other cases (e.g., the southern pine beetle, '' Dendroctonus frontalis''), wood tissue is the main food, and fungi weaken the defense response from the host plant. Some species of phoretic mites that ride on the beetles, have their own type of mycangium, but for historical reasons, mite taxonomists use the term acarinarium. Apart from riding on the beetles, the mites live together ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Abdomen
The abdomen (colloquially called the gut, belly, tummy, midriff, tucky, or stomach) is the front part of the torso between the thorax (chest) and pelvis in humans and in other vertebrates. The area occupied by the abdomen is called the abdominal cavity. In arthropods, it is the posterior (anatomy), posterior tagma (biology), tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between Lumbar vertebrae, L5 and Vertebra#Sacrum, S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body cavity enclosed by the abdominal muscles, at the front an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oviposition
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 , 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 tissues of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
