Vespa Luctuosa
''Vespa luctuosa'' is a species of hornet which is endemic (ecology), endemic to the Philippines. The main subspecies is ''Vespa luctuosa luctuosa'' (primarily native to Luzon, Luzon island). Other known subspecies include ''Vespa luctuosa luzonensis'' (primarily native to the Visayas, including Leyte, Leyte island and Samar Island) and ''Vespa luctuosa negrosensis'' (native to Negros island). ''Vespa luctuosa'' is known for its potent venom. Venom characteristics The venom of ''Vespa luctuosa'' has the highest recorded toxicity to mice of any wasp species tested. The of the venom is 1.6 mg/kg. The toxicity (measured against mice) per weight of ''Vespa luctuosa'' venom is higher than that of the larger Asian giant hornet (''Vespa mandarinia''), which has an LD50 of 4.0 mg/kg, but which is responsible for many more human deaths than ''Vespa luctuosa'' due to the considerably larger volume of venom injected per sting. In addition to being the most venomous known wasp, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cebu City
Cebu City, officially the City of Cebu, is a Cities of the Philippines#Legal classification, highly urbanized city in the Central Visayas region of the Philippines. According to the 2020 census, it has a population of 964,169 people, making it the sixth-most populated city in the nation and the most populous in the Visayas and the Central Visayas Region. It serves as the capital of Cebu wherein it is geographically situated and grouped under the province by the Philippine Statistics Authority, but is one of three cities (together with Lapu-Lapu City, Lapu-Lapu and Mandaue) that are administratively independent of the provincial government and also the largest city within that province.

Pogonomyrmex
''Pogonomyrmex'' is a genus of harvester ants, occurring primarily in the deserts of North, Central, and South America, with three endemic species from Haiti.Cole, A.C. 1968. Pogonomyrmex Harvester Ants: a study of the genus in North America. University of Tennessee Press, Knoxville, TN. Description The genus name originated from the Greek language and refers to a beard-like structure, the psammophore, below the head (Greek πώγων/''pōgōn'', "beard" + μύρμηξ/''murmēx'', "ant"), which can be found in most species of the subgenus '' sensu stricto''. The psammophore is used for gathering small seeds, helping to increase the efficiency of transportation of fine sand and pebbles during nest construction, or to carry eggs. However, this structure is missing in species of the subgenus ''Ephebomyrmex'' (Greek ἔφηβος/''ephēbos'', "beardless lad"), and these species generally have smaller individuals and colonies. Venom ''Pogonomyrmex'' (''sensu stricto'') workers ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of The Philippines
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becom ...

Insects Of The Philippines
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of Asia
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they reach adulthood. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vespidae
The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as '' Polistes fuscatus'', '' Vespa orientalis'', and ''Vespula germanica'') and many solitary wasps. Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter. New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, while others are notable predators of pest insect species, and a f ...

Hematuria
Hematuria or haematuria is defined as the presence of blood or red blood cells in the urine. "Gross hematuria" occurs when urine appears red, brown, or tea-colored due to the presence of blood. Hematuria may also be subtle and only detectable with a microscope or laboratory test. Blood that enters and mixes with the urine can come from any location within the urinary system, including the kidney, ureter, urinary bladder, urethra, and in men, the prostate. Common causes of hematuria include urinary tract infection (UTI), kidney stones, viral illness, trauma, bladder cancer, and exercise. These causes are grouped into glomerular and non-glomerular causes, depending on the involvement of the glomerulus of the kidney. But not all red urine is hematuria. Other substances such as certain medications and some foods (e.g. blackberries, beets, food dyes) can cause urine to appear red. Menstruation in women may also cause the appearance of hematuria and may result in a positive urine dips ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanosis
Cyanosis is the change of Tissue (biology), tissue color to a bluish-purple hue, as a result of decrease in the amount of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. Cyanosis is apparent usually in the Tissue (biology), body tissues covered with thin skin, including the mucous membranes, lips, nail beds, and ear lobes. Some medications may cause discoloration such as medications containing amiodarone or silver. Furthermore, mongolian spots, large birthmarks, and the consumption of food products with blue or purple dyes can also result in the bluish skin tissue discoloration and may be mistaken for cyanosis. Appropriate physical examination and history taking is a crucial part to diagnose cyanosis. Management of cyanosis involves treating the main cause, as cyanosis is not a disease, but rather a symptom. Cyanosis is further classified into central cyanosis and peripheral cyanosis. Pathophysiology The mechanism behind cyanosis is different dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convulsions
A convulsion is a medical condition where the body muscles contract and relax rapidly and repeatedly, resulting in uncontrolled shaking. Because epileptic seizures typically include convulsions, the term ''convulsion'' is often used as a synonym for ''seizure''. However, not all epileptic seizures result in convulsions, and not all convulsions are caused by epileptic seizures. Non-epileptic convulsions have no relation with epilepsy, and are caused by non-epileptic seizures. Convulsions can be caused by epilepsy, infections (including a severe form of listeriosis which is caused by eating food contaminated by Listeria monocytogenes), brain trauma, or other medical conditions. They can also occur from an electric shock or improperly enriched air for scuba diving. The word ''fit'' is sometimes used to mean a convulsion or epileptic seizure. Signs and symptoms A person having a convulsion may experience several different symptoms, such as a brief blackout, confusion, drooling, l ...

Pogonomyrmex Maricopa
''Pogonomyrmex maricopa'', the Maricopa harvester ant, is one of the most common species of harvester ant found in the U.S. state of Arizona, but it is also known from California, Colorado, New Mexico, Nevada, Texas and Utah, and the Mexican states of Baja California, Chihuahua, Sinaloa and Sonora. Its venom is believed to be the most toxic insect venom in the world. Their nest mounds are likely to incorporate rocks and gravel. The ants construct cemented caps on the sand mound nests in a fine sand dune area. The caps are approximately 60% calcium carbonate that is transported from the underlying calcium carbonate layers, and protect the nest structure from being eroded away during high-wind periods. Partial erosion of the cemented caps adds calcium carbonate to the sand dune soils. Venom and attack method The toxicity of the venom of the Maricopa harvester ant is well known. Its LD50 value is 0.12 mg/kg (injected intravenously in mice); 12 stings can kill a 2-kg rat. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asian Giant Hornet
The Asian giant hornet (''Vespa mandarinia''), also known as the northern giant hornet, and the Japanese giant hornet, is the world's largest hornet. It is native to temperate and tropical East Asia, South Asia, mainland Southeast Asia, and parts of the Russian Far East. It was also found in the Pacific Northwest of North America in late 2019, with a few more additional sightings in 2020, and nests found in 2021, prompting concern that it could become an invasive species, but in December 2024, the hornets were announced to have been eradicated from the region, as well as from the rest of the United States.New York Times: Asian giant hornets prefer to live in low mountains and forests, while almost completely avoiding plains and high-altitude climates. ''V. mandarinia'' creates nests by digging, co-opting pre-existing tunnels dug by rodents, or occupying spaces near rotten pine roots. It feeds primarily on larger insects, colonies of other eusocial insects, tree sap, and honey fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
