Brickellia
''Brickellia'' is a North American genus of about 100 to 110 species of plants in the family Asteraceae, known commonly as brickellbushes. They are found in Canada, the United States, Mexico, and Central America. Many species are native to the American southwest, especially Texas. ''Brickellia'' is among the more basal lineages of the Eupatorieae and should not be assigned to a subtribe pending further research. They are mostly woody perennial shrubs. Some species have a very strong pleasant scent, while others smell distasteful. All contain high amounts of essential oils. Germacrene D, a natural insecticide, is found in '' B. veronicifolia'' and probably other species, if not all. Despite their chemical defenses, brickellbushes are food for caterpillars of certain Lepidoptera. These include the noctuid moths ''Schinia trifascia'', ''Schinia oleagina'', which is known only from ''Brickellia'', ''Schinia buta'', which is only known from '' B. californica'', and ''Schinia gr ...

Germacrene
Germacrenes are a class of volatile organic hydrocarbons, specifically, sesquiterpenes. Germacrenes are typically produced in a number of plant species for their antimicrobial and insecticidal properties, though they also play a role as insect pheromones. Two prominent molecules are germacrene A and germacrene D. Structures Germacrene has five isomers.

Polemoniaceae
The Polemoniaceae (Jacob's-ladder or phlox family) are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversity in western North America. Only one genus (''Polemonium'') is found in Europe, and two (''Phlox'' and ''Polemonium'') in Asia, where they are confined to cool temperate to arctic regions; both genera also occur more widely in North America, suggesting relatively recent colonization of the Old World from North America. The family can be distinguished from most other eudicot families by the ovary made up of three fused carpels (usually with three chambers, but with one chamber in some species). The members of the family have five sepals, five petals fused, and five stamens that alternate with the lobes of the corolla. For decades, most sources used a classification of the family published by Grant in 1959, but new evidence, including mol ...

Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noctuidae
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae. Description Adult: Most noctuid adults have drab wings, but some subfamilies, such as Acronictinae and Agaristinae, are very colorful, especially those from tropical regions (e.g. ''Baorisa hieroglyphica''). They are characterized by a structure in the metathorax called the nodular sclerite or epaulette ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
