Coridius Janus
''Coridius janus'', sometimes known as the red pumpkin bug, is a species of bug in the family Dinidoridae. It feeds by sucking on the sap on soft parts of plants especially in the cucurbit family and causes damage to crops. The species was originally described in the genus ''Cimex'' by Fabricius and later placed in the genus ''Aspongopus''. The antenna is five segmented with the third segment longer than the first which is shorter than all other segments, the body outline is oval. The scutellum is short and has a rounded apex. The proboscis tip extends past the coxae of the first pair of legs. They are yellowish to orange red in colour with a black stripe on the anterior pronotal edge sometimes broke in the middle. The basal half of the scutellum and the membrane of the forewing is also black. The species is widely distributed in tropical South and Southeast Asia but has spread to other parts of the world. ''Coridius janus'' has been used in numerous physiological and anatomic s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinidoridae
The Dinidoridae are a small family of insects comprising about a hundred species in sixteen genera in the Hemipteran suborder Heteroptera, the "true bugs".Lis, Jerzy A; Lis; Pawel; Ziaja, Dariusz J; Kocorek, Anna. Systematic position of Dinidoridae within the superfamily Pentatomoidea (Hemiptera: Heteroptera) revealed by the Bayesian phylogenetic analysis of the mitochondrial 12S and 16S rDNA sequences. Zootaxa 3423: 61–68 (2012) ISSN 1175-5334 As a group the family does not have any common name. Until the late 19th century they were generally regarded as a subfamily of the Pentatomidae. Description Most members of the family Dinidoridae are large and robust in build; the bodies of some species may exceed 27 mm in length. In shape they are ovoid to oblong. The head and pronotum have lateral keels. The scutellum is moderately short and blunt, typically some 50% of the abdominal length. The antennae have four or five segments, with at least two of the subapical segmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Red Pumpkin Bugs (within The Family Of Pentatomidae; Shield Bugs Or Stink Bugs) Captured At Noon
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century ...

Undecane
Undecane (also known as hendecane) is a liquid alkane hydrocarbon with the chemical formula CH3(CH2)9CH3. It is used as a mild sex attractant for various types of moths and cockroaches, and an alert signal for a variety of ants.Hölldobler B, Wilson EO (1990). ''The Ants''. Harvard University Press. , p. 287 It has 159 isomers. Undecane may also be used as an internal standard in gas chromatography when working with other hydrocarbons. Since the boiling point of undecane (196 °C) is well known, it may be used as a comparison for retention times in a gas chromatograph for molecules whose structure has been freshly elucidated. For example, if one is working with a 50 m crosslinked methyl silicone capillary column with an oven temperature increasing slowly, beginning around 60 °C, an 11-carbon molecule like undecane may be used as an internal standard to be compared with the retention times of other 10-, 11-, or 12- carbon molecules, depending on their structures.
