Elcysma Westwoodi
''Elcysma westwoodi'' (often spelled ''Elcysma westwoodii''), commonly known as the white-tailed zygaenid moth, is a species of moth in the burnet moth family Zygaenidae. It has a Palaearctic distribution, being found in Japan, the Korean Peninsula, China, and the Russian Far East. The species was first described by Samuel Constantinus Snellen van Vollenhoven in 1863 as ''Agalope westwoodii''. The white-tailed zygaenid is particularly known for its status as an agricultural pest for members of the family Rosaceae, and has been described as the most damaging pest for '' Prunus yedoensis'' trees. Studies have been conducted on the potential for the use of endoparasites in mitigating the extent of damage on crop trees. ''Elcysma westwoodi'' is known as ウスバツバメ, ''usuba-tsubame'' in the Japanese language. The Japanese common name alludes to the swallow, of which the moth's hindwings resemble the tails of. In Korean, it is known as 벚나무모시나방, ''beojnamumosi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Claspers
In biology, a clasper is a male anatomical structure found in some groups of animals, used in mating. Male cartilaginous fish have claspers formed from the posterior portion of their pelvic fin which serve to channel semen into the female's cloaca during mating. The act of mating in some fish including sharks usually includes one of the claspers raised to allow water into the siphon through a specific orifice. The clasper is then inserted into the cloaca, where it opens like an umbrella to anchor its position. The siphon then begins to contract, expelling water and sperm. The claspers of many shark species have spines or hooks, which may hold them in place during copulation. Male chimaeras have cephalic claspers (tenacula) on their heads, which are thought to aid in holding the female during mating. In entomology, it is a structure in male insects that is used to hold the female during copulation (see Lepidoptera genitalia for more). See also *Sexual coercion among animals ...

Cerambycid
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short (e.g., '' Neandra brunnea'') and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns. Description Other than the typical long antennal length, the most consistently distinctive feature of the family is that the antennal sockets are located on low tubercles on the face; other beetles with long antennae lack these tubercles, and cerambycids with short antennae still possess them. They otherwise vary greatly in size, shap ... [...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 '' 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 th ...

Sexual Selection
Sexual selection is a mode of natural selection in which members of one biological sex choose mates of the other sex to mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex (intrasexual selection). These two forms of selection mean that some individuals have greater reproductive success than others within a population, for example because they are more attractive or prefer more attractive partners to produce offspring. Successful males benefit from frequent mating and monopolizing access to one or more fertile females. Females can maximise the return on the energy they invest in reproduction by selecting and mating with the best males. The concept was first articulated by Charles Darwin who wrote of a "second agency" other than natural selection, in which competition between mate candidates could lead to speciation. The theory was given a mathematical basis by Ronald Fisher in the early 20th century. Sexual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olfaction
The sense of smell, or olfaction, is the special sense through which smells (or odors) are perceived. The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste. In humans, it occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system. Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion. There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease. History of study Early scientific study of the sense of smell includes the extensive doctoral dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheromones
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are '' alarm pheromones'', ''food trail pheromones'', '' sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). Pher ...

Voltinism
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. nort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monandrous
In botanical terms, monandrous simply means to have a single stamen. In orchids A distinction between monandrous and other flowers is particularly relevant in the classification of orchids. The monandrous orchids form a clade consisting of the subfamilies Orchidoideae, Vanilloideae, and Epidendroideae. The other subfamilies, Apostasioideae and Cypripedioideae, have at least two stamens. In animals In animals, a monandrous system occurs when females have one mate at a time. For example, a female speckled wood butterfly will typically only mate once within her short lifetime. This is also common in certain bee species, like ''Bombus terrestris'' and '' Bombus pratorum'', where a female will only mate with one male during her nuptial flight and use the sperm reserves for the rest of her life. This is also seen in a few species of stingless bees, like '' Plebeia remota'', where the males will attempt to mate with the queen as she tries to leave the nest, but only one male w ...

Sclerotin
Sclerotin is a component of the cuticle of various Arthropoda, most familiarly insects. It is formed by cross-linking members of particular classes of protein molecules, a biochemical process called sclerotization, a form of tanning in which quinones are enzymatically introduced into the cuticle, and react with terminal and lysine-related amino groups in the proteins to form strong links between the molecules.Chapman, R.F. (1969) ''The Insects: Structure and Function''. Elsevier, New York. Chapter 22.37 - "Expansion of the new cuticle is brought to an end by the onset of tanning" The resulting material increases the rigidity of an insect's chitinous exoskeleton. It is particularly prominent in the thicker, armoured parts of insect and arachnid integument, such as in the biting mouthparts and sclerites of scorpions and beetles. As it matures, freshly formed sclerotin becomes a hard, horn-like substance with a range of yellow-brown colors. As animals adapted to life on land, increa ...
