Archips Cerasivorana
''Archips cerasivorana'', the ugly-nest caterpillar moth, is a species of moth of the family Tortricidae. The caterpillars of this species are known to create nests by tying the leaves of their host plant together. Within the nests, they live and feed off the leaves that have been tied together. The larvae are brownish or greenish yellow with a shiny dark brown head. Larvae can be found from May to July. The species overwinters as an egg, and pupation takes place within the nest. Caterpillars are seen to follow one another in trails, a behavior prompted by the release of signaling pheromones from their spinnerets. ''A. cerasivorana'' is found throughout North America, as far north as Alaska and as far south as North Carolina. The wingspan is 20–25 mm. The forewings are dull orange marked with irregular dark brownish spots. The hindwings are yellow with orange shading. Adults can be found from July to September in one generation per year.

Asa Fitch
Asa Fitch (February 24, 1809 – April 8, 1879) was a natural historian and entomologist from Salem, New York. His early studies were of both natural history and medicine, which he studied at the newly formed Rensselaer Polytechnic Institute, graduating in 1827. However, in 1838 he decided to start studying agriculture and entomology. In 1838 he began to collect and study insects for New York state. In 1854 he became the first professional entomologist of New York State Agricultural Society (commissioned by the State of New York). This made him the first occupational entomologist in the United States. His vast studies of many insects helped scientists to solve some of the problems of crop damage caused by insects. Many of his notebooks are now the property of the Smithsonian Institution. Fitch also discovered the rodent botfly ''Cuterebra emasculator'' in 1856. He died April 8, 1879, in Salem, New York. The Martin–Fitch House and Asa Fitch Jr. Laboratory was added to the Nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instars
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 ...

Bacillus Thuringiensis
''Bacillus thuringiensis'' (or Bt) is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide. ''B. thuringiensis'' also occurs naturally in the gut of caterpillars of various types of moths and butterflies, as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, and flour mills and grain-storage facilities. It has also been observed to parasitize other moths such as ''Cadra calidella''—in laboratory experiments working with ''C. calidella'', many of the moths were diseased due to this parasite. During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called delta endotoxins, that have insecticidal action. This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes, such as Bt corn. Many crystal-producing Bt strains, though, do not have insecticidal properties. The subspecies ''israelensis'' is commonly used for control of mosq ...

Spinneret (spider)
A spinneret is a silk-spinning organ of a spider or the larva of an insect. Some adult insects also have spinnerets, such as those borne on the forelegs of Embioptera. Spinnerets are usually on the underside of a spider's opisthosoma, and are typically segmented. While most spiders have six spinnerets, some have two, four, or eight. They can move both independently and in concert. Most spinnerets are not simple structures with a single orifice producing a single thread, but complex structures of many microscopic spigots, each producing one filament. This produces the necessary orientation of the protein molecules, without which the silk would be weak and useless. Spigots can be singular or found in groups, which also permits spiders to combine multiple filaments in different ways to produce many kinds of silk for various purposes. Spinneret morphology can help arachnologists identify the taxon of a specimen and the specific morphology of a spigot can determine its use as well ...

Pheromones
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). Pheromones ...

Tent
A tent () is a shelter consisting of sheets of fabric or other material draped over, attached to a frame of poles or a supporting rope. While smaller tents may be free-standing or attached to the ground, large tents are usually anchored using guy ropes tied to stakes or tent pegs. First used as portable homes by nomads, tents are now more often used for recreational camping and as temporary shelters. Tents range in size from " bivouac" structures, just big enough for one person to sleep in, up to huge circus tents capable of seating thousands of people. Tents for recreational camping fall into two categories. Tents intended to be carried by backpackers are the smallest and lightest type. Small tents may be sufficiently light that they can be carried for long distances on a touring bicycle, a boat, or when backpacking. The second type are larger, heavier tents which are usually carried in a car or other vehicle. Depending on tent size and the experience of the person or people in ...

Eclosion
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosis ...

Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities.

Chokecherry
''Prunus virginiana'', commonly called bitter-berry, chokecherry, Virginia bird cherry, and western chokecherry (also black chokecherry for ''P. virginiana'' var. ''demissa''), is a species of bird cherry (''Prunus'' subgenus ''Padus'') native to North America. Description Chokecherry is a suckering shrub or small tree growing to tall, rarely to and exceptionally with a trunk as thick as . The leaves are oval, long and wide, with a serrated margin. The stems rarely exceed in length. The flowers are produced in racemes long in late spring (well after leaf emergence), eventually growing up to 15 cm. They are across. The fruits (drupes) are about in diameter, range in color from bright red to black, and possess a very astringent taste, being both somewhat sour and somewhat bitter. They get darker and marginally sweeter as they ripen. They each contain a large stone. Chemistry Chokecherries are very high in antioxidant pigment compounds, such as anthocyanins ...
