Cassida Viridis Schildkäfer (Chrysomelidae)
''Cassida'' is a large Old World genus of tortoise beetles in the subfamily Cassidinae. The natural history of Cassida sphaerula in South Africa is a typical life cycle. Several species of ''Cassida'' are important agricultural pests, in particular ''Cassida vittata, C. vittata'' and ''Cassida nebulosa, C. nebulosa'' on sugar beet and spinach. The thistle tortoise beetle (''Cassida rubiginosa'') has been used as a biological control agent against Canada thistle. The genus name is derived from Latin ''Cassis'' for a metal helmet. There are at least 430 described species in ''Cassida''. This genus contains the most species of all Cassidinae. Larvae build shields with their feces and exuviae, a widespread pattern of tortoise beetles.Chaboo, C.S., S. Adam, K. Nishida, L. Schletzbaum. 2023.

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biological Control Agent
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insects play an important part in limiting the densities of potential pests. Biological control agents such as these include predators, parasitoids, pathogens, and comp ...

Thistle Tortoise Beetle
The thistle tortoise beetle (''Cassida rubiginosa'') is a species of beetle in the subfamily Cassidinae (tortoise beetles) and the genus ''Cassida.'' The thistle tortoise beetle can be recognized by its green, rounded back and it can be found on thistle plants in many regions of North America and Europe. The thistle tortioise beetle was first discovered in 1902 in Lévis, Quebec. In 1931, Nellie F. Paterson was the first to document the mature larva. Later, the instar larva of this species was first recorded in 2004 by Jolanta Świętojańska. The thistle tortoise beetle exhibits multiple defense behaviors, such as a flexible shield, providing a barrier against the mandibles of predators, and an excretion that protects the eggs as well. Its ability to massively consume and damage Thistle, thistle plants has also made this beetle a well known biological control agent in many countries, including the United States, Canada, and Switzerland. However, in some cases, the impact of these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sugar Beet
A sugar beet is a plant whose root contains a high concentration of sucrose and that is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet (''Beta vulgaris''). Together with other beet cultivars, such as beetroot and chard, it belongs to the subspecies ''Beta vulgaris'' subsp. ''vulgaris'' but classified as ''var. saccharifera''. Its closest wild relative is the sea beet (''Beta vulgaris'' subsp. ''maritima''). Sugar beets are grown in climates that are too cold for sugarcane. In 2020, Russia, the United States, Germany, France and Turkey were the world's five largest sugar beet producers. In 2010–2011, Europe, and North America except Arctic territories failed to supply the overall domestic demand for sugar and were all net importers of sugar. The US harvested of sugar beets in 2008. In 2009, sugar beets accounted for 20% of the world's sugar production and nearly 30% by 2013. Sugarcane accounts for most ...

Agricultural Pest
A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; wolves, snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food; beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats and cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' (Latin; the English title is ''A General System of Nature'') is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassidinae
The Cassidinae (tortoise and leaf-mining beetles) are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra. Description The "cassidoids" have a rounded outline with the edges of the pronotum and elytra expanded, spreading out to cover the legs and head. They are often colourful and metallic, with ornate sculpturing; a few species have the ability to change colour due to water movements within the translucent cuticle. All members of the subfamily have the mouthparts reduced into a cavity in the head capsule, the legs have four segmented tarsi. The hispoids have larvae that are ecological diverse as leaf miners or cryptic exophagous feeders, while the cassidoids feed freely externally ...
