Putoidae
Putoidae is a family of scale insects commonly known as giant mealybugs or putoids. There is probably a single genus, ''Puto'', containing about sixty species. The genus name ''Macrocerococcus'' has also been used but it is now considered to be a synonym of ''Puto''. The genus ''Puto'' was formerly classified as a member of the Pseudococcidae; however, it so significantly differed from the rest of the Pseudococcidae that it was accorded its own family Putoidae. Hosts Giant mealybugs occur on a wide range of hosts, each species having its own specific host. Host plants commonly include conifers, grasses and various woody shrubs. All parts of the plant can be infested. Description The adult female is oval and up to five millimetres long and concealed by tufts of powdery white wax. If the wax is removed, two longitudinal black stripes can be seen on the upper surface of the body and the wax glands are large and conspicuous. The legs and antennae are well developed and a dark colour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale Insects
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Pseudococcidae
Mealybugs are insects in the family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Many species are considered pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector for several plant diseases. Some ants live in symbiotic relationships with them, protecting them from predators and feeding off the honeydew which they excrete. Description Mealybugs are sexually dimorphic: females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Since mealybugs (as well as all other Hemiptera) are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. However, male mealybugs do exhibit a radical change during their life cycle, changing from wingless, ovoid nymphs to wasp-like flying adults. Mealybug females feed on plant sap, nor ...

Zoologische Mededelingen
''Zoologische Mededelingen'' was a peer-reviewed open access scientific journal publishing papers and monographs on animal systematics. The publisher was the National Museum of Natural History Naturalis in the Netherlands. The first issue appeared in 1915, as the official journal of Naturalis' predecessor, the Rijks Museum van Natuurlijke Historie. Earlier, the museum published ''Muséum d'Histoire Naturelle des Pays-Bas'' (volumes I-XIV, 1862-1908) and ''Notes from the Leyden Museum'' (volumes I-XXXVI, 1879-1914), which mainly covered the fauna of the Netherlands and the former Dutch colonies. ''Zoologische Mededelingen'' was indexed in ''The Zoological Record'' and ''BIOSIS''. A complete backlist of published volumes is presented on the institutional repository of Naturalis. The last article was published in 2014 and the journal was merged into the ''European Journal of Taxonomy The ''European Journal of Taxonomy'' is a peer-reviewed open access scientific journal for descrip ...

Victor Antoine Signoret
Victor Antoine Signoret (6 April 1816, Paris – 3 April 1889, Paris) was a French pharmacologist, physician and entomologist. In 1845 Signoret gained his doctorate in pharmacology at the University of Paris. His thesis was entitled ''De l'Arsenic considéré sous ses divers points de vue''. Pharmacology made him a wealthy man and he made many collecting trips mainly in Europe but also in Asia Minor. His very important collection is in the Naturhistorisches Museum, Vienna, Austria although there is significant material in La Specola museum in Florence. Signoret worked on Hemiptera, and is considered to be one of the first great students of Coccoidea ( mealybugs and scale insects). He established methods for the preparation of slides for the examination of mealybug morphology. He wrote over 80 papers, including a ''Revision du groupe des Cydnides'' (1881–1884) and he was a Member of the Entomological Society of France, as well as an honour Fellow of the Entomological Soc ...

Annals Of The Entomological Society Of America
Annals ( la, annāles, from , "year") are a concise historical record in which events are arranged chronologically, year by year, although the term is also used loosely for any historical record. Scope The nature of the distinction between annals and history is a subject based on divisions established by the ancient Romans. Verrius Flaccus is quoted by Aulus Gellius as stating that the etymology of ''history'' (from Greek , , equated with Latin , "to inquire in person") properly restricts it to primary sources such as Thucydides's which have come from the author's own observations, while annals record the events of earlier times arranged according to years. White distinguishes annals from chronicles, which organize their events by topics such as the reigns of kings, and from histories, which aim to present and conclude a narrative implying the moral importance of the events recorded. Generally speaking, annalists record events drily, leaving the entries unexplained and equally we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...
