Iridomyrmecin
Iridomyrmecin is a defensive chemical, classified as an iridoid, isolated from ants of the genus ''Iridomyrmex''. It has also evolved into a sex pheromone in wasps such as ''Leptopilina'', with host species using the smell of iridomyrmecin as a way of detecting the presence of the parasitoid wasps. Iridomyrmecin is also found in a variety of plants including ''Actinidia polygama ''Actinidia polygama'' (also known as , silver vine, , and cat powder) is a species of kiwifruit in the Actinidiaceae family.

Iridoid
Iridoids are a type of monoterpenoids in the general form of cyclopentanopyran, found in a wide variety of plants and some animals. They are biosynthetically derived from 8-oxogeranial. Iridoids are typically found in plants as glycosides, most often bound to glucose. The chemical structure is exemplified by iridomyrmecin, a defensive chemical produced by the ant genus ''Iridomyrmex'', for which iridoids are named. Structurally, they are bicyclic ''cis''-fused cyclopentane-pyrans. Cleavage of a bond in the cyclopentane ring gives rise to a subclass known as ''secoiridoids'', such as oleuropein and amarogentin. Occurrence The iridoids produced by plants act primarily as a defense against herbivores or against infection by microorganisms. The variable checkerspot butterfly also contains iridoids obtained through its diet which act as a defense against avian predators. To humans and other mammals, iridoids are often characterized by a deterrent bitter taste. Aucubin and catal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iridomyrmex
''Iridomyrmex'' is a genus of ants called rainbow ants (referring to their blue-green iridescent sheen) first described by Austrian entomologist Gustav Mayr in 1862. He placed the genus in the subfamily Dolichoderinae of the family Formicidae. It has 79 described species and five fossil species. Most of these ants are native to Australia; others are found in Asia and Oceania, and they have been introduced to Brazil, New Zealand, and the United Arab Emirates. Fossil species are known from China, France, and the United States. These ants are known to be an ecologically dominant and important group of ants, but they are sometimes regarded as pests because they disturb soil and enter human houses. Farmers in rural Australia place animal carcasses on meat ant ('' I. purpureus'') mounds as a method of disposing of them; meat ants consume the carcass and reduce it to bones in a matter of weeks. Meat ants also engage in ritualised fighting, which helps prevent casualties and solve te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptopilina
''Leptopilina'' is a genus of parasitoid wasp in the family Figitidae. The genus is best known for the three Drosophila parasitoids ''Leptopilina boulardi'', ''Leptopilina heterotoma'' and ''Leptopilina clavipes,'' used to study host-parasite immune interactions. The venom released by L. heterotoma during oviposition contains virus-like particles that delay host larval development and suppress the host cellular immune response. There is no evidence that these virus-like particles are the products of viral DNA as described in other parasitoid taxa. '' L. japonica'' is a parasitoid of ''Drosophila suzukii'' which is an important pest in fruit production. First captured in November 2020 as bycatch from a ''Vespa mandarinia'' trap in Washington State Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinidia Polygama
''Actinidia polygama'' (also known as , silver vine, , and cat powder) is a species of kiwifruit in the Actinidiaceae family. It grows in the mountainous areas of Korea, Japan and China at elevations between . Silver vine can reach up to high at maturity. It is a deciduous climber and tolerates temperatures down to . The petiole leaves are silver and white in color and long and wide. These colorful markings make the plant identifiable from afar, until the flowering season when the leaves turn completely green. The flowering season lasts from late June to early July, in which the plant bears white flowers about in diameter. The longevity of an individual flower is 2–3 days, when the plant also starts to develop small, yellow to yellow-red, egg-shaped, fleshy, and multiseeded fruits, which mature from September to October. The fruit is about wide and long. The inside of the fruit resembles the common kiwifruit, but it is orange in color rather than green. The silver vine ...

Cat Pheromone
A cat pheromone is a chemical molecule, or compound, that is used by cats and other felids for communication. These pheromones are produced and detected specifically by the body systems of cats and evoke certain behavioural responses. The name of the pheromone that calms a cat is Apaisins. Cat pheromones are commonly released through the action of scent rubbing. As such, one of the main proposed functions of pheromone release is to allow the cat to familiarize itself with its surroundings and other individuals, both in the newborn and adult stages of life. Specific cat pheromones that have been chemically identified include the feline facial pheromones F1-F5, the feline appeasing pheromone, and MMB in urine, most of which are associated with distinct feline behaviours. Some of these chemical makeups have been synthetically reproduced and may be used by cat owners or veterinary professionals looking to change problematic or stress-induced behaviours. Production and detection The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactones
Lactones are cyclic carboxylic esters, containing a 1-oxacycloalkan-2-one structure (), or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring. Lactones are formed by intramolecular esterification of the corresponding hydroxycarboxylic acids, which takes place spontaneously when the ring that is formed is five- or six-membered. Lactones with three- or four-membered rings (α-lactones and β-lactones) are very reactive, making their isolation difficult. Special methods are normally required for the laboratory synthesis of small-ring lactones as well as those that contain rings larger than six-membered. Nomenclature Lactones are usually named according to the precursor acid molecule (''aceto'' = 2 carbon atoms, ''propio'' = 3, ''butyro'' = 4, ''valero'' = 5, ''capro'' = 6, etc.), with a ''-lactone'' suffix and a Greek letter prefix that specifies the number of carbon atoms in the heterocycle — that is, the distance between the relevant -OH ...
